Visa and Mastercard Expand Stablecoin Payment Partnerships

97d ago · Source: cryptonews

Visa and Mastercard have expanded direct partnerships with cryptocurrency firms to issue cards and settlement services using stablecoins, a development that aligns with a 2014 prediction about traditional payment companies working with Bitcoin startups.

In 2014, former Electronic Transactions Association CEO Jason Oxman said payment firms would accommodate new technologies based on consumer and merchant demand, not endorse any specific system. He added that the industry existed to facilitate electronic transactions, regardless of the technology used for those payments. At that time, BitPay became the first digital currency company to join the payments trade group.

Visa and Stripe‑owned Bridge announced in March a plan to roll out stablecoin‑linked Visa cards to more than 100 countries by the end of 2026, allowing users to spend stablecoin balances through Visa’s merchant network. Visa’s stablecoin settlement pilot, which now involves nine blockchains, reached a $7 billion annualized settlement volume in April. Mastercard’s Crypto Partner Program includes over 100 crypto companies, financial institutions and payment providers; Alchemy Pay joined the program in May to develop fiat‑onchain payment links. The industry focus has shifted from Bitcoin to stablecoins, with Visa, Mastercard and Coinbase supporting Open Standard, a consortium developing the Open USD stablecoin for business payments. BitPay obtained MiCA authorization in the Netherlands, enabling it to provide regulated crypto and stablecoin services across eligible EU markets.

The expansion of stablecoin payment infrastructure by major card networks suggests continued rollout of blockchain‑based payment options, though regulatory clarity remains a pending factor.

Michael Saylor Warns Bitcoin BIP‑110 Could Undermine Network Neutrality

97d ago · Source: coindesk

Michael Saylor, executive chairman and co‑founder of Strategy, warned on July 19, 2026 that Bitcoin Improvement Proposal 110 (BIP‑110) could threaten the network’s neutrality and create market uncertainty.

BIP‑110 proposes a one‑year soft fork that would temporarily limit arbitrary data stored on the Bitcoin blockchain and lower the miner‑signaling threshold required for consensus changes from 95% to 55%.

Saylor argued that the proposal would use consensus rules to restrict valid activity, potentially leading to a network split and weakening miner incentives. He said that fee markets and relay policies, rather than protocol changes, should address concerns about spam.

He noted his firm holds 843,775 BTC, valued at approximately $54.3 billion, making it the largest publicly listed bitcoin treasury, and said that altering consensus rules could discourage developers and reduce aggregate fee demand, thereby affecting miner security.

Saylor described the 55% threshold as overly aggressive and said that lowering the approval requirement could encourage disagreement and increase the chance of a fork.

He suggested that market‑based fees and individual relay policies are sufficient tools to manage data usage without changing the core consensus rules, emphasizing that Bitcoin needs guardians of neutrality rather than purity.

The proposal remains under discussion, and the community has not yet indicated whether the changes will be adopted.

Grayscale to Distribute Quarterly Cash Payouts from Ethereum and Solana Staking Rewards

97d ago · Source: cryptoslate

Grayscale plans to begin quarterly cash payouts of staking rewards from its Ethereum and Solana funds, with the first distribution expected around Aug. 7. The company said it will amend the trust agreements for the Grayscale Ethereum Staking ETF (ETHE) and the Grayscale Solana Staking ETF (GSOL) to convert staking rewards into cash at least once per quarter.

In SEC filings submitted on July 17, Grayscale outlined that the cash distributions would be made after expenses are covered and that the amount and timing of each payout would depend on the rewards actually earned during the relevant period. The filings note that the schedule sets a minimum frequency rather than a fixed payout date or amount.

The proposed structure would enable a like‑for‑like comparison of net cash returns, disclosed expense drag and timing between the two assets, and builds on an earlier cash distribution from ETHE in January that paid about $0.083 per share.

Under Revenue Procedure 2025‑31, qualifying grantor trusts may distribute net staking rewards in cash no less frequently than quarterly, and Grayscale’s agreements specify cash sales of the native assets before passing proceeds to shareholders. Holders would recognize staking rewards as taxable income when the trust receives them, and selling the assets to fund the payout may generate additional capital gains or losses.

The changes could enhance transparency for investors and affect fee competition among crypto ETF providers, though final approval from the SEC and holder‑specific tax consequences remain pending.

Japanese Logistics Firm AZ‑COM Maruwa Holdings Plans to Use JPYC Stablecoin for Driver Payments

97d ago · Source: cointelegraph

Japanese logistics firm AZ‑COM Maruwa Holdings plans to use the yen‑denominated stablecoin JPYC to pay about 2,300 business partners, including truck drivers. This would represent the first large‑scale corporate use of the token in Japan.

The company, which lists Amazon Japan as a major client, said the stablecoin would enable faster, fee‑free payments for fees and compensation to contractors.

According to Nikkei, JPYC would reduce payment processing time and eliminate transfer fees. AZ‑COM Maruwa is evaluating a partnership with JPYC Inc. and plans to invest more than 1 billion yen (about $6.2 million).

Co‑founder and CEO Noritaka Okabe said the firm will continue to integrate logistics and payment workflows using JPYC.

Sony Bank and JPYC are separately testing instant yen purchases for customer accounts.

The development could expand stablecoin usage in Japanese business payments.

Allbridge Core Pauses Cross-Chain Bridge After $1.65M Exploit

97d ago · Source: cointelegraph

Allbridge Core announced it has paused its cross-chain bridge following a security incident that resulted in the loss of $1.65 million from its Solana deployment, which occurred on Sunday.

The pause is the sixth attack on a cross-chain bridge since May, a trend that reflects the attractiveness of these platforms to attackers because they hold large pools of assets that back bridged tokens on destination blockchains.

According to a post on X, Allbridge said the protocol was paused as a precaution while it investigates; users with liquidity in the affected pools were advised to withdraw their assets immediately. On‑chain analysis indicated the attacker obtained a $1.12 million USDC flash loan from the Kamino platform, executed rapid USDC‑USDT swaps that distorted the stablecoin pool’s exchange rate, and then withdrew liquidity at manipulated rates, repaid the flash loan and retained the difference. The manipulation created a temporary arbitrage opportunity; the post asked participants who profited to consider returning the funds to help compensate affected liquidity providers.

The company has previously been targeted in a flash‑loan attack in April 2023 that drained $573,000 across the BNB Chain, and other recent bridge exploits include $1.7 million stolen from Taiko in June, a $4.67 million “infinite mint” attack on Secret Network, and attacks on Gravity Bridge, Verus Bridge and the Butter Network.

Allbridge has not disclosed the root cause of the current incident, and the timeline for resuming service remains unclear while the investigation proceeds.

Spot Bitcoin ETFs See $273 Million Inflow, Ending Eight-Week Outflow Streak

97d ago · Source: coindesk

U.S.-listed spot bitcoin exchange‑traded funds attracted $273 million in inflows over the two weeks ending July 20, ending an eight‑week outflow streak that totaled more than $8 billion, according to data from SoSoValue. Spot bitcoin ETFs are exchange‑traded funds that provide exposure to bitcoin without requiring investors to hold the underlying cryptocurrency, and they are listed on U.S. securities exchanges. The inflows consisted of $75.67 million in the week ended June 17 and $197.40 million the prior week, the firm reported. That amount is less than the smallest weekly outflow during the previous eight‑week decline, which was $226.84 million in the week ended June 18. Ecoinometrics described the flow balance as having improved and suggested that longer‑term inflows were reappearing, while a crypto analysis firm, BRN, advised that multi‑week positive trends would be needed to confirm a structural shift. Bitcoin’s price has hovered between $64,000 and $65,000 in recent days, having peaked above $126,000 in October 2025. Until weekly inflows consistently exceed recent outflows, the data do not indicate a definitive return of large‑scale institutional demand, and the current activity remains modest relative to the broader market movement.

Kraken Launches USD‑Settled Bitcoin and Ether Options

97d ago · Source: coindesk

Kraken has introduced USD‑settled options for bitcoin and ether on its Kraken Pro platform, initially available via request‑for‑quote to eligible international clients outside Europe, North America and Australia, with a European rollout planned later. The launch follows growing institutional interest in crypto derivatives and competition among exchanges, as derivatives dominate crypto trading volume while options remain a small segment dominated by venues such as Deribit, CME Group and Binance. Kraken's product is linear, USD‑settled and integrates with existing spot and futures accounts, offering portfolio margin by default and collateral in over 30 currencies, and includes educational tools to help traders understand calls, puts and multi‑leg strategies. Kraken's director of derivatives, Alexia Theodorou, said the firm views options as an underpenetrated market compared with traditional finance and that design, not demand, has limited adoption. The exchange plans to add a public order book, expand geographic coverage and support additional assets, with Europe as the next focus, leveraging existing regulatory permissions. The move reflects Kraken's broader strategy to evolve from a crypto exchange into a full‑service financial platform, though the impact on market size remains to be seen.

AZ‑COM Maruwa Holdings to Use JPYC Stablecoin for Payments to 2,300 Logistics Partners

97d ago · Source: cryptonews

Japanese logistics firm AZ‑COM Maruwa Holdings announced plans to use the yen‑backed JPYC stablecoin for payments to about 2,300 partner carriers and independent drivers, according to a Nikkei report. AZ‑COM Maruwa, which provides third‑party logistics, transportation, warehousing and delivery services, will invest ¥1 billion in JPYC and form a partnership with the stablecoin issuer. The rollout would extend the stablecoin beyond retail trials and limited crypto services into routine business payments across a large logistics network. The company said the partnership would cover outsourcing and other payments made to its network of transport partners, including individual truck drivers. It has not disclosed a detailed rollout schedule or explained how each partner will receive, hold or convert the tokens. Other pilots are already testing JPYC in Japan. Lawson plans to trial JPYC payments at a Tokyo convenience store in August using a point‑of‑sale system, and LINE NEXT intends to support JPYC through Unifi Pay, a stablecoin payment service slated for a third‑quarter launch. JPYC, launched on October 27 2025, maintains a one‑to‑one peg with the yen and holds reserve assets in Japanese government bonds and bank deposits. Regulators have required that most reserve proceeds be invested in government bonds. The scale of the planned payments would provide a significant test of whether a regulated yen‑backed stablecoin can function in everyday corporate settlement, though implementation details remain pending.

Bitcoin Climbs as Inflation Data Softens and Consumer Spending Holds Steady

97d ago · Source: cryptoslate

Bitcoin rose to about $64,700 after a June inflation report indicated headline consumer prices fell 0.4% month‑over‑month to an annual 3.5%, the biggest one‑month decline since 2020, largely because of lower energy costs; the price movement followed a 0.2% increase in June retail sales that was driven mainly by cheaper gasoline. The inflation report showed that the entire decline was due to falling energy prices, while core inflation, which excludes food and energy, stayed at 2.6% annually; retail sales data, which are not adjusted for inflation, showed a 0.2% rise in June, with gasoline stations posting the largest decline in sales since December 2022 because fuel prices fell during the ceasefire. When gasoline and automobile sales are excluded, retail sales increased 0.4%, and the measure used in gross domestic product calculations rose 0.5%, led by gains in online shopping and car dealers; real spending, adjusted for inflation, reached its highest level since early 2022; consumer spending has grown faster than personal income, prompting households to draw on savings or use credit; inflation expectations for the next year rose to 3.7%, the highest since 2023, driven by anticipated rises in medical expenses (9.4%) and rent (8.3%); industrial production was flat in June, with manufacturing output unchanged and durable goods production declining, while capacity utilization fell to 75.7%; the Federal Reserve kept its target rate between 3.50% and 3.75% and nine of its 18 officials indicated they expect at least one further rate increase this year, with market participants assigning a 50% to 63% probability of a September hike. Oil prices have risen more than 15% since the June ceasefire ended, suggesting that July inflation figures may show renewed upward pressure, while the combination of core inflation remaining unchanged, weak manufacturing growth, and consumer spending that outpaces income raises questions about the Fed’s ability to cut rates and the outlook for risk assets such as Bitcoin.

Cardano Activates Van Rossem Hard Fork, Moving to Protocol Version 11

97d ago · Source: cryptonews

Cardano’s mainnet activated the van Rossem hard fork on July 18, moving the network to Protocol Version 11.

The upgrade, the first decided through on‑chain governance, updates Plutus cost models and prepares the network for the Ouroboros Leios upgrade.

The proposal was ratified on July 13 by delegated representatives, stake pool operators and the Constitutional Committee, achieving 77.63% DRep and 52.7% SPO support.

The hard fork follows testing on Preview and Preprod networks and introduces cheaper smart‑contract operations.

Input Output said the upgrade lays the foundation for the Dijkstra era hard fork that will bring Ouroboros Leios, which aims to increase transaction throughput while preserving security.

Van Rossem marks the first Cardano hard fork executed under Voltaire on‑chain governance, replacing the earlier coordination model used by the founding development groups.

The community previously rejected a 7.8 million ADA request for the 2026 Cardano Summit, while treasury funds support ongoing work on Leios, Hydra and Mithril.

Development on Dijkstra and Leios continues, with no announced launch date, though the scaling upgrade is expected later in 2026.

Michael Saylor, executive chairman of Strategy, posted on X.com on Sunday detailing 110 reasons he believes Bitcoin Improvement Proposal 110 is a poor approach to limiting non‑monetary transactions on the Bitcoin network. BIP‑110, introduced in December 2025, seeks to curb ordinals inscriptions and other arbitrary data to preserve Bitcoin’s primary use as a peer‑to‑peer cash system. The proposal requires support from 55% of validating nodes over a block period; in the most recent period only 1% of blocks signaled support. The proposal was drafted by pseudonymous developer Dathon Ohm and endorsed by Ocean protocol founder Luke Dashjr, while Blockstream CEO Adam Back has voiced opposition. Daily ordinal inscriptions have fallen to fewer than 10,000 from a peak of over 400,000 in August 2023, according to Dune Analytics. Saylor’s 3,700‑word post, which received 879,000 views, 692 replies and 852 retweets by 12 p.m. ET on Sunday, stated that he shares the objective of keeping validation accessible and preserving affordable payments but disagrees with the remedy. He emphasized that the critique targets the proposal, not the individuals behind it, and called for vigorous disagreement without mistaking allies for enemies. The debate mirrors the blocksize discussions of 2015‑2017, and the proposal includes a temporary one‑year limit that would not invalidate fee‑paying transactions beyond that period. The proposal must achieve the 55% node threshold to activate, and no such activation has occurred to date.

South Korea Reports 40 Cases of Crypto Market Manipulation Since 2024 Law Took Effect

97d ago · Source: cryptonews

South Korean financial authorities have opened more than 40 investigations into alleged cryptocurrency market manipulation and other unfair trading under the Virtual Asset User Protection Act, which took effect on July 19, 2024. The law marked its second anniversary on July 19, 2026. Lee Eog-won, chair of the Financial Services Commission, said the cases involved suspected manipulation, wash trading and other fraudulent activities. More than 30 cases were referred to investigative agencies and 25 individuals were identified as suspects. Lee said average unlawful gains per case reached about 1.4 billion Korean won, roughly $940,000. He added that regulators will strengthen AI‑based surveillance and monitoring systems, focusing on high‑risk areas.

The Virtual Asset User Protection Act requires virtual asset service providers to keep customer holdings separate from company assets and to deposit user funds with banks. It also gives regulators authority to inspect providers and to act against insider trading, wash trading and market manipulation. South Korean officials have used those powers in recent enforcement actions, including two cases referred to prosecutors earlier this month. One case involved a trader accused of acquiring close to half of a token’s circulating supply before selling into rising demand. Regulators have warned about sharp price and volume movements linked to low‑liquidity tokens. The Financial Intelligence Unit referred about 40 unregistered crypto operators to law enforcement in June and warned users about risks from platforms operating outside the registration system. The government is also moving to extend state asset management rules to cover digital assets beyond real estate.

Regulators have not released a complete public list of the 40‑plus cases or the status of each referral. As the two‑year milestone passes, officials say they will continue to improve AI‑driven surveillance and monitoring to protect crypto market participants.

Zcash to Activate Ironwood Hard Fork on July 28 Seal Orchard Pool

97d ago · Source: cryptonews

Zcash will activate its Ironwood hard fork on July 28, retiring the Orchard shielded pool and introducing a corrected pool based on the NU6.3 upgrade. According to Zcash founder Zooko Wilcox, the upgrade addresses a flaw discovered by security researcher Taylor Hornby on May 29 that could permit creation of counterfeit ZEC without public record. The bug allowed an attacker to generate additional ZEC within the Orchard pool while concealing the transaction. The Ironwood upgrade, also known as NU6.3, will activate at block 3,428,143 and will seal the old Orchard pool, preventing further transfers except through a turnstile that limits withdrawals to the amount originally deposited. After activation, users will no longer be able to send or receive ZEC within the Orchard pool; funds must be moved to the new pool before the upgrade takes effect. Exchanges and wallet providers are expected to update their software, which may result in temporary suspensions of deposits, withdrawals, or other services. The Zcash team said the network believes the flaw was unlikely to have been exploited, but the privacy of the Orchard pool means that past exploitation cannot be proven with absolute certainty. An AI‑assisted review using Anthropic’s Mythos system found no additional serious vulnerabilities after the original issue was disclosed, and developers are pursuing independent audits and formal verification of the updated cryptographic system. The hard fork does not identify or freeze individual counterfeit coins; its purpose is to prevent any hypothetical excess supply from entering wider circulation. Zcash has moved away from its legacy zcashd client, and providers still completing that migration may require additional time to support Ironwood fully. Users are advised to ensure their wallets support the new pool before the July 28 activation.

MetaMask Source Code Access Granted North Korea‑Linked Contractor for One Month

97d ago · Source: cryptoslate

Consensys halted MetaMask code releases in April after discovering that a contractor with ties to North Korea had accessed the repository from March 9. The contractor was engaged through a third‑party provider and worked on MetaMask code until access was cut off. Consensys said its investigation found no evidence of asset misappropriation, malicious code deployment, or impact on user safety. General Counsel Matt Corva said the company identified the threat quickly, terminated the contractor’s access, launched a comprehensive investigation, and notified law enforcement. An internal alert in April instructed staff to suspend product releases pending the investigation and told staff not to interact with the consultant. Consensys said it characterized the service‑provider relationship as reputable and noted that it has reviewed its third‑party service practices to ensure the same rigorous standards applied to employees also cover outside relationships. The incident highlighted gaps in contractor access controls, prompting Consensys to reinforce requirements such as verified identification, multi‑interview screening, hardware authentication, IP and location verification, reference checks, and limited access to critical systems. The FBI has warned that North Korean IT workers have used similar remote‑work setups to copy code repositories. Guidance from the UK National Cyber Security Centre recommends attributing repository activity, reviewing all production‑bound changes, applying extra scrutiny to external contributions, and revoking access quickly when it is no longer required. Consensys said it will retain a predefined way to halt changes while suspicious access is investigated, underscoring the need for continuous monitoring of contractor privileges.

US Agencies Miss Stablecoin Rulemaking Deadline under GENIUS Act

97d ago · Source: cointelegraph

US regulatory agencies missed the Saturday deadline for issuing final rules under the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, which was signed into law on July 18, 2025. While several agencies published proposed rules and solicited public comment during the past year, none completed the final rulemaking process before the deadline, according to tracking data from law firm Chapman and crypto investment firm Paradigm. The agencies that missed the deadline include the Department of the Treasury, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, the Federal Reserve Board, and the National Credit Union Administration. The Treasury issued four proposed rule packages covering implementation standards, interstate regulatory similarity, registration of foreign issuers, and anti‑money‑laundering compliance, while the OCC issued two proposals addressing nationally chartered payment stablecoin issuers and supervisory expectations. The FDIC issued one proposal for FDIC‑supervised institutions that issue payment stablecoins, focusing on reserve management and operational standards. The NCUA proposed rules allowing federally insured credit unions to participate in stablecoin issuance, and federal banking agencies jointly released an interagency implementation rule to align supervisory expectations. The absence of final regulations creates uncertainty for stablecoin issuers and market participants, according to industry analysts. On the one‑year anniversary of the law, Anchorage Digital urged Congress to pass the Digital Asset Market Clarity Act (CLARITY), which would extend regulatory framework concepts to the broader digital asset sector. The CLARITY Act cleared the Senate Banking Committee in May and has been discussed in letters from state banking associations that seek clearer guidance on stablecoin yield provisions. The agencies have not set a new timeline for final rule issuance, and the industry awaits further legislative or regulatory action.

Cardano activated its Van Rossem hard fork on Saturday, moving the mainnet to protocol version 11, a step intended to reduce smart contract execution costs and prepare for the Ouroboros Leios scalability upgrade. The upgrade represents the first governance‑driven hard fork in Cardano’s history, distinguishing it from earlier updates that were coordinated directly by Input Output, the firm that designed the blockchain. Onchain data from Cardanoscan show the network transitioned from version 10 in epoch 643 to version 11 in epoch 644. In a weekly development report, Input Output said the upgrade includes Plutus improvements, a revised Plutus cost model, and sets the foundation for the upcoming Dijkstra era hard fork that will introduce Ouroboros Leios. Ouroboros Leios is a scaling proposal for the Ouroboros proof‑of‑stake consensus, projected to launch in late 2026 and aims to increase transactions per second while preserving security guarantees. The change marks a milestone in Cardano’s roadmap, though the full impact of the upgrade and the timing of the Leios rollout remain to be seen.

Bitcoin Holds $64,000 as Oil Rises to One-Month High and AI Selloff Persists

97d ago · Source: coindesk

Bitcoin hovered near $64,200 on Monday, showing little change, while Brent crude rose 4% to $91.42 a barrel, its highest level since June, as U.S. and Iranian strikes widened beyond military targets. The price increase raised inflation concerns and prompted expectations that the Federal Reserve may hold rates steady, putting pressure on risk assets such as cryptocurrencies. Simultaneously, Moonshot AI’s Kimi K3 model, a Chinese open‑weight language model that led a prominent coding benchmark, triggered a selloff in semiconductor stocks that weighed on the broader market and contributed to a modest decline in crypto prices.

Bitcoin remained roughly flat on the day and was up about 3% for the week, with roughly $18 billion of trading volume. Ether gained 5% to $1,860, marking its strongest weekly performance among major cryptocurrencies, while XRP stayed at $1.09, Solana at $76, BNB at $565 and dogecoin near $0.07. Hyperliquid’s HYPE dropped 10% to $60, extending a week‑long decline without a specific catalyst beyond the overall risk‑off tone.

Equity markets showed mixed reactions: South Korea’s Kospi fell 3.5% as traders returned from a holiday, while U.S. futures steadied with the Nasdaq 100 up 0.5%.

Analysts noted that the week’s focus will be on corporate earnings rather than macro data, as no major U.S. economic releases are scheduled. Alphabet is set to report earnings on Tuesday, Tesla on Wednesday and Intel on Thursday; their results may clarify whether the recent volatility in AI‑related chip stocks and the miner‑to‑AI investment trend still has support.

The balance between oil‑driven inflation worries and the effect of the Chinese AI model on technology stocks remains unresolved as the market awaits earnings reports.

Project Eleven Develops Zero-Knowledge Proof to Recover Quantum-Vulnerable Bitcoin

97d ago · Source: coindesk

Project Eleven said it has built a zero‑knowledge proof system that could enable recovery of bitcoin held in addresses made vulnerable by the BIP‑361 proposal, including the roughly 1.1 million BTC linked to Satoshi Nakamoto.

BIP‑361, published in April by Jameson Lopp and five co‑authors, would block new deposits to quantum‑vulnerable addresses after three years and freeze existing coins after five years, affecting more than a third of bitcoin’s total supply.

The system creates a proof that a user knows the seed material above an address in a hierarchical derivation tree, binds the proof to a migration transaction, and does not reveal the seed. Benchmarks show proof generation of 243 ms on a four‑core MacBook Air, verification of 40 ms, and memory usage of about 2 GB, with no GPU required; the author reports the proof runs 16 times faster than prior work and up to 60 times faster when the one‑time setup is excluded.

Quantum computers could derive private keys from public keys using Shor’s algorithm, rendering signatures meaningless after a theoretical “Q‑Day”. More than 34 % of bitcoin resides in addresses whose public keys are exposed.

The prototype is unaudited, supports three address types, and does not yet recover any coins on a live network. Lopp has said he dislikes BIP‑361 because it conflicts with the principle of permanent ownership, and the main objection is that freezing coins appears to violate that promise; a functional recovery proof would turn the freeze into a lock rather than a burn.

Since the recovery relies on a derivation tree introduced by BIP‑32 in February 2012, it cannot be applied to Satoshi’s coins or to wallets created before that date, and the proposal still awaits consensus changes before it could protect any coins.

Eight Steam Games Linked to Crypto Malware Campaign Infected Thousands of Devices and Stole Funds

97d ago · Source: cryptoslate

The FBI is seeking potential victims of an eight‑game malware campaign that infected roughly 8,000 Steam accounts, accessed about 80 cryptocurrency wallets and resulted in the theft of at least $220,000, according to a federal complaint unsealed on July 14.

The case illustrates how compromised software distribution platforms can expose wallet credentials before a user even opens a wallet, prompting the agency to issue a notice to anyone who downloaded the implicated titles between May 2024 and January 2026.

The complaint alleges that the campaign, promoted through Discord, Telegram, X and LinkedIn, used bots to target users with large crypto holdings and encouraged them to install games such as BlockBlasters, Chemia, Dashverse, DashFPS, Lampy, Lunara, PirateFi and Tokenova. Once installed, the malware captured private data, credentials and, in some instances, authorized transactions that drained wallet balances. The FBI’s onboarding documentation for Steam states that initial game builds are vetted, but updates can be deployed without additional review, a gap the alleged actors may have exploited. Local 10 reported that agents arrested 21‑year‑old Zyaire Dontaevious Zamarion Wilkins on July 14 and charged him with financing and procuring the malware and assisting in its distribution. Investigators traced Bitcoin payments from a compromised wallet to the service Bitrefill, which was used to purchase more than 150 digital gift cards, primarily for Uber Eats; a subpoena to Uber then linked those cards to an account with delivery addresses tied to Wilkins. The FBI’s notice indicates that PirateFi was available on Steam from February 6 to February 12, 2025 and contained the Vidar infostealer, which can steal credentials, session cookies and wallet information.

The incident underscores that wallet security depends on multiple layers beyond software distribution, and that on‑chain transaction trails can aid investigations until funds are converted through off‑ramps such as gift‑card services; the case remains under investigation.

Circle President Defends USDC Strategy Amid Competitor Pressure and Stock Decline

97d ago · Source: cryptonews

Circle President Heath Tarbert said the company remains focused on building long‑term financial infrastructure after its shares fell 17.5 % to $62.63 following the launch of Open USD, a new stablecoin supported by a consortium of payment and financial firms.

USDC, which had about $73 billion in circulation and operated on 34 blockchains, is described by Circle as the largest regulated stablecoin with the highest transaction volume.

Open USD was launched by Open Standard, a group that includes Visa, Mastercard, Stripe, BlackRock, BNY, and Coinbase, and allows partners to mint and redeem the token without fees while sharing reserve earnings after a management charge.

Circle received final OCC approval on July 10 to create Circle National Trust, a regulated entity that will initially provide digital‑asset custody, with USDC reserve management planned for a later stage.

Tarbert said management is playing a long game and argued that the stock’s performance should improve if Circle successfully expands its internet‑based financial platform.

Analysts have expressed concern that Open USD’s revenue‑sharing model could pressure Circle’s margins and reduce distribution costs.

JPMorgan lowered its earnings forecasts for Circle and Coinbase after a new revenue‑sharing agreement linked to USDC balances on Hyperliquid, citing the potential for lower reserve income.

Mizuho reduced its price target for Circle to $50, saying Open USD’s structure could erode profit margins.

Circle continues to expand regulated infrastructure despite the share decline, with the newly approved trust bank expected to support broader institutional use of its digital‑asset services.

Whether the competitive pressure from Open USD will affect Circle’s long‑term revenue sharing and stock valuation remains to be seen.

Allbridge Core paused its cross‑chain stablecoin protocol after a security incident on Solana that resulted in an estimated $1.65 million loss, according to PeckShield. The exploit involved a $1.12 million USDC flash loan from Kamino that the attacker used to manipulate the USDC/USDT liquidity pool on Allbridge Core, creating a temporary arbitrage opportunity. Onchain Lens reported that the attacker performed rapid swaps to alter pool balances, withdrew liquidity at distorted rates, and repaid the flash loan within the same transaction. The stolen assets were transferred from Solana to Ethereum via the bridge. Allbridge urged liquidity providers to withdraw their funds while the investigation continued and asked anyone who profited from the arbitrage to consider returning funds to a recovery address. The incident follows a prior April 2023 exploit on the BNB Chain that caused about $573,000 in losses, of which roughly $465,000 was recovered after a white‑hat reward. Other recent cross‑chain attacks include a May Verus‑Ethereum bridge loss exceeding $11.5 million and a Transit Finance exploit of about $1.88 million. Allbridge has not set a reopening date and has not released a technical report, stating that the pause is precautionary while the investigation proceeds.

South Korea Initiates Sanctions Proceedings Against Dunamu Over Upbit Wallet Breach

97d ago · Source: cryptonews

South Korea’s Financial Supervisory Service opened formal sanctions proceedings against Dunamu, the operator of the Upbit cryptocurrency exchange, following a November 2025 wallet breach that affected Solana‑based assets. The breach, which early estimates placed at about $36 million, was later valued by Korean authorities at 44.5 billion won (approximately $32 million). Upbit reimbursed customers, restored wallet services, and moved assets to cold storage while the regulator examined compliance with the Virtual Asset User Protection Act. The FSS issued an inspection opinion letter to Dunamu, giving the company an opportunity to respond before any penalty is imposed. Current law does not prescribe specific sanctions for hacking or system failures, creating uncertainty over the potential severity of the measures. The regulator will review Dunamu’s response and may refer the case to the sanctions review committee, the Securities and Futures Commission and the Financial Services Commission for further action. Upbit previously faced a 35.2 billion won fine for anti‑money‑laundering and customer verification failures; a court later canceled a partial suspension of that sanction due to legal basis issues. The latest breach occurs amid broader regulatory scrutiny of cryptocurrency platforms in South Korea, where the government is considering additional rules to address hacking and technology failures in upcoming digital asset legislation. Dunamu is also engaged in a delayed share swap with Naver Financial, which has been postponed to December 31 pending regulatory approvals; the current inspection does not block the transaction but subjects the company to multiple layers of review. The FSS has not announced a proposed sanction level, and Dunamu may contest the inspection findings before a final decision is made.

US Stock-Bond Correlation Turns Positive as Treasury Yields Rise, Bitcoin Faces Pressure

97d ago · Source: cryptoslate

The two‑month rolling correlation between the S&P 500 and the 10‑year Treasury yield was -0.69 in 2026, the lowest reading since 1996, according to UBS. That level indicates that stocks and bonds are moving together more often than they have in three decades.

Historically, the inverse relationship between equities and Treasuries provided a buffer when stocks declined, a dynamic that underpinned many investment products and shaped portfolio allocations for two decades. The correlation began to weaken around 2020 and has remained negative through 2026, a shift driven by rising inflation volatility rather than a single change in inflation levels.

The 30‑year Treasury yield rose above 5% for the first time since 2007 and hovered near 5.1% as of July 16. A $25 billion auction of new 30‑year bonds cleared above 5% earlier in the year, the first such sale in 18 years. US fiscal deficits are projected to widen from about 5.8% of GDP in 2026 to 6.7% by 2036, with net interest payments increasing as a share of the economy.

Foreign demand for US debt has thinned. Japanese investors sold $29.6 billion of US government, agency and local authority debt in the first quarter of 2026, the largest net sale since 2022, as domestic yields became more attractive. Japan’s 10‑year yield rose above levels last seen in 1997, and Germany’s 10‑year Bund reached 15‑year highs, reflecting a broader withdrawal of global demand.

Investors have shifted toward short‑dated, low‑duration assets such as cash and bills, which carry minimal interest‑rate risk. The sell‑off in the long end of the curve has raised yields and tightened liquidity, supporting the dollar while pressuring assets that rely on duration.

Bitcoin has become as sensitive to macro conditions as the dollar and gold. Its price tends to rise when real yields fall, the dollar weakens, or financial conditions ease. A rally in Treasuries that lowers yields can therefore support Bitcoin, whereas a sustained rise in yields compresses the equity risk premium and raises the opportunity cost of holding a non‑yielding asset.

Societe Generale research suggests that a 10‑year yield around 4.5% marks a threshold where the relationship between yields and equities turns hostile. Below that level, rising yields and rising stocks can coexist; above it, higher yields tend to drag equities down. Goldman Sachs reached a similar conclusion, noting that the rise in yields has compressed the equity risk premium to a level where investors receive limited compensation for bearing stock risk.

Regulators in Washington have struggled to sustain a bid for Bitcoin this year, as macro‑driven yield pressure outweighs crypto‑specific developments.

The current environment removes a traditional floor beneath risk assets. If inflation volatility subsides and growth risk becomes the dominant market driver again, the historic inverse correlation may re‑emerge, potentially restoring a safe haven for equities and reducing Bitcoin’s exposure to Treasury yield movements.

South Korean Regulator Begins Sanctions Process Against Dunamu Over $36 Million Upbit Hack

97d ago · Source: cointelegraph

South Korean financial regulator began a sanctions procedure against Dunamu, the operator of crypto exchange Upbit, after a $36 million hack of the platform in November 2025.

The Financial Supervisory Service sent an inspection opinion letter to Dunamu, giving the company an opportunity to respond before any proposed sanctions are announced, according to Yonhap News. Upbit faced criticism for delaying its public notice of the breach, which occurred at 4:42 a.m. KST on November 27 and was not disclosed until later that day after a Naver Financial merger event.

The regulator is reviewing whether Upbit violated the Virtual Asset User Protection Act, which does not currently contain specific sanctions for cyberattacks. Upbit initially froze about 2.3 billion won (≈ $1.5 million) in assets and pledged to reimburse affected customers from its balance sheet. The exchange subsequently overhauled its wallet architecture and migrated assets from compromised wallets. In December 2025 it launched an on‑chain tracking service, the Onchain AI Tracer System, to follow the movement of stolen funds. Upbit ranks third among crypto spot exchanges on CoinMarketCap and reported a 24‑hour trading volume of $478.56 million.

The regulator plans to amend the Digital Asset Basic Act to add sanctions and compensation provisions for hacks and system failures.

The sanctions process remains pending, and the outcome will determine any further regulatory action against Upbit.

South Korea Probes 30 Unfair Trading Cases in Crypto Market Over Two Years

97d ago · Source: cointelegraph

South Korea’s financial authorities investigated more than 40 cases of unfair trading and crypto fraud between July 2024 and June 2026, referring 30 cases to investigative agencies and identifying 25 suspects, according to a statement from Financial Services Commission Chair Lee Eog‑won. The probe was launched under the Virtual Asset User Protection Act, enacted in July 2024 to bring the cryptocurrency market within a regulatory framework and to protect users by requiring virtual asset service providers to keep client deposits separate from corporate holdings and to store those assets in banks. The legislation targets illicit activities such as insider trading, wash trading and market manipulation and expands the Financial Services Commission’s authority to supervise and inspect virtual asset service providers. Lee said the enforcement reflects two years of regulatory integration and noted that the average unlawful gain per case was roughly 1.4 billion Korean won ($940,000). He added that the commission will continue to enhance market surveillance using artificial intelligence and respond proactively to high‑risk areas. The investigation remains ongoing as authorities monitor compliance within the virtual asset ecosystem.

GENIUS Act Marks One Year as U.S. Moves to Regulate Stablecoins

97d ago · Source: coindesk

President Donald Trump signed the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act into law on July 19, 2025, establishing the first federal framework for stablecoin regulation. A year later, agencies continue to develop detailed rules.

The law instructs the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation and other agencies to define how stablecoin issuers must manage reserves, governance and operational matters, leaving specific requirements to be drafted.

In an emailed statement, Crypto Council for Innovation chief executive Ji Hun Kim described the legislation as a landmark moment and said that agencies, institutions and innovators are building on a clearer foundation as stablecoins move toward greater mainstream use. Proposed regulations would require stablecoin issuers to conduct know‑your‑customer checks comparable to those required of traditional financial firms. The FDIC released a list of 144 questions concerning custody, capital and liquidity standards, while the OCC issued a separate proposal in February outlining its interpretation of the statute. Implementation of the final rules is expected after several months of comment periods.

Senate leaders Cynthia Lummis and Bernie Moreno briefed Trump on the related Digital Asset Market Clarity Act on Thursday, though no public summary of the meeting was released. Lawmakers have raised concerns about an ethics provision that would bar senior officials from profiting from crypto ventures; a bipartisan consensus on this issue has not yet emerged. Senator Elizabeth Warren has asked Trump to provide a financial disclosure covering the first half of 2026, noting that his 2025 disclosure reported more than $1.4 billion in crypto‑related earnings and that the filing deadline for the 2026 report is May 15, 2027. A House Financial Services subcommittee held a hearing on Friday in which Chair Bryan Steil said Congress aims to replace enforcement‑driven regulation with clear rules for digital assets, emphasizing the historic role of U.S. financial innovation.

The legislative and regulatory process remains ongoing, and the timeline for final rules and the passage of the Clarity Act is still uncertain.

UK Extends Criminal Liability to Crypto Firms over Iran's IRGC Designation

97d ago · Source: cryptoslate

The United Kingdom added Iran's Islamic Revolutionary Guard Corps (IRGC) to Schedule 6A of the National Security Act 2023, creating a new criminal offense under Section 17C. The provision can impose up to 14 years in prison and a fine on any person who obtains, accepts, or retains a benefit from the designated body while knowing, or reasonably ought to have known, the source of the benefit.

The law, which does not mention crypto assets explicitly, applies to money or anything of value supplied directly or indirectly, including through companies, exchanges, custodians, payment processors, and other intermediaries. Liability hinges on the connection between the benefit and the IRGC and on the recipient’s knowledge at the time of the transaction.

Crypto firms that receive, hold, or facilitate value must therefore track wallet attributions, the timing of knowledge acquisition, and whether the benefit can be linked to the IRGC. While the legislation does not make an Iran‑linked payment automatically criminal, it adds a separate potential liability that may arise weeks or months after a transfer is settled on the blockchain.

The statute preserves exemptions for ordinary business considerations and humanitarian activity, and it does not create a blanket ban on Iranian crypto transactions. Firms are advised to maintain detailed evidentiary records of attribution, confidence levels, and response actions to address potential Section 17C exposure.

Bitcoin Treads Near $52,900 Low as Sellers Tire and Demand Remains Weak

97d ago · Source: cryptoslate

Bitcoin fell about 18% to near $52,900, a level that analysts consider a key support test after sellers showed signs of fatigue. The recent buyer cost basis stands near $69,000, while the realized price, based on on‑chain data, is about $52,891. A sustained move above $69,000 would indicate a higher low, whereas a break below $52,891 could expose the broader market to net unrealized loss. Glassnode reported that long‑term holder loss realization accounted for 43% of total realized value on July 8, and its entity‑adjusted long‑term‑holder realized‑loss series turned down for the first time since its cycle peak. The entity‑adjusted series had peaked near $280 million per day, the highest reading since December 2022. Spot Bitcoin ETFs returned to net inflows in early July, according to a Glassnode market pulse dated July 13, though weekly data showed redemptions slowing and inflows remaining limited. Trading volume contracted and spot cumulative volume delta turned negative during the recovery, the same report noted. The market now appears to be in a phase where sellers are easing before buyers have fully arrived, leaving the possibility of a higher low contingent on price and demand confirmation. Whether Bitcoin can hold above the recent buyer cost basis will determine if the market stabilizes or resumes decline.

Wall Street Private Credit Exposure Grows Amid BDC Losses

97d ago · Source: cryptoslate

A Reuters analysis of 53 publicly traded business development companies found that 28 posted losses in the first quarter of 2026, up from 12 a year earlier, as profit margins fell to negative $7.6 million per company.

Business development companies, or BDCs, are publicly traded funds that lend to mid‑sized firms unable to obtain bank loans and distribute most earnings as dividends. The analysis combined standardized financial data from S&P Global Market Intelligence and covered the period through March 2026.

The average annual profit declined from positive $26 million to negative $7.6 million, driven by loan markdowns and higher borrowing costs. Net investment income reported by BDCs can mask debt expense and valuation changes, and payment‑in‑kind financing accounted for about 8.1 percent of interest and dividend income in 2025, double the share before 2020. Off‑balance‑sheet borrowings through joint ventures and special‑purpose entities rose 94 percent in 2025 and the first quarter of 2026, moving leverage beyond headline balance sheets.

JPMorgan Chase, Citigroup, Bank of America and Wells Fargo collectively hold more than $128 billion in private credit exposure, with JPMorgan alone at roughly $50 billion and Wells Fargo’s financials‑except‑banks portfolio at $210.2 billion, including $36.2 billion in direct private credit loans.

Direct‑lending volume in the United States fell about 55 percent quarter over quarter, from $74.67 billion to $33.59 billion, while private debt issuance totaled $87.2 billion through May 2026, down 24.6 percent from the same period in 2025. Investor redemptions exceeded $20.8 billion in the first quarter, with managers approving less than half of the requests and limiting withdrawals to 5 percent of net asset value for many funds.

While private credit stress does not directly set Bitcoin prices, tighter bank funding lines reduce loan supply, curb corporate financing and buyout activity, and diminish risk appetite, which can depress crypto valuations. Bitcoin traded near $63,900 in mid‑July 2025, about 38 percent lower than a year earlier, as credit market concerns grew.

Regulators note that hidden leverage in private credit remains difficult to measure, and the contrast between bank confidence and mounting BDC losses suggests that systemic risk could emerge if funding lines tighten.
