GIWA has rejected claims that its mainnet RPC endpoint was leaked, stating that the Ethereum Layer 2 network has not yet launched a mainnet. The project clarified that its mainnet remains under development, making any leak of a live mainnet RPC impossible. Official documentation lists only GIWA Sepolia testnet RPC endpoints, while the mainnet infrastructure is still being built. GIWA runs on the OP Stack and relies on Ethereum as its settlement layer, with a one-second block time and a 60 million gas limit per block. The network does not currently issue a native token; transaction fees are paid in ETH, though stablecoin-based fees may be introduced later via a Paymaster system. Upbit partnered with Optimism to construct GIWA using the OP Stack under a self-managed OP Enterprise model, granting Upbit control over its own infrastructure while receiving technical support from Optimism. The project’s website labels GIWA Wallet and its planned stablecoin ecosystem as “Coming Soon,” and developers are directed to use the Sepolia testnet for testing, which offers a public RPC endpoint at sepolia-rpc.giwa.io and a Flashblocks test endpoint for faster preconfirmation. Both endpoints are rate limited and intended for development. GIWA’s smart contract documentation shows deployed contracts on Sepolia but marks the mainnet section as under development, and a separate Flashblocks document lists the mainnet endpoint as “Coming soon.” The clarification follows social-media assertions of a leaked mainnet RPC, which GIWA did not specify or verify. No evidence was provided indicating that the Sepolia testnet RPC was compromised. The project urged users to “DYOR” and remain vigilant against misinformation and scams prior to launch. GIWA’s technical specifications include compatibility with Ethereum Virtual Machine tools, support for Solidity development, and a sequencer for block ordering, while Ethereum provides the underlying Layer 1 settlement. The network’s current design does not include a native token, and its FAQ states that ETH serves as the base asset for fees. Upbit’s involvement in GIWA was first disclosed earlier in 2026, positioning the project as part of Dunamu’s broader push into blockchain infrastructure beyond its exchange operations. Several other South Korean firms previously linked to stablecoin initiatives have similarly denied formal commitments. GIWA’s present statement focuses narrowly on the RPC leak claim, reaffirming that no mainnet has launched and that all mainnet-related endpoints remain unpublished. Developers may operate their own nodes or use the free Sepolia RPC endpoint, though the project recommends external node services for future production workloads. The project’s public materials continue to indicate that mainnet features are “under development” or “coming soon,” with no announced launch date.
