MANTRA Chain resumed block production after deploying version 8.4.0 to address a vulnerability in its Cosmos‑EVM module that had halted the network for about 30 hours. The network restarted at approximately 5:30 a.m. UTC on August 22. The mainnet had been stopped on August 20 after developers detected an exploit in an upstream dependency, which froze transactions, staking, bridges and other functions. Two MANTRA‑managed wallets were identified as affected, but user balances remained unchanged and no token holder action was required. Developers traced the issue to the Cosmos‑EVM component, built the patch, and coordinated upgrades of validators, node operators, RPC services and archive nodes before initiating the restart. Block production returned at about 5:30 a.m. UTC, roughly 30 hours after the last recorded block at 11:13 p.m. UTC on August 20. Public RPC and EVM endpoints became operational, while explorers and indexers lagged as they processed post‑restart data; the testnet DuKong remained offline. MANTRA said a complete post‑incident report would be released in the coming days. During the outage the MANTRA token fell from approximately $0.005060 to a low of $0.004126, a decline of about 18.5%, with trading volume rising near 600% to $24 million. The project stated the price movement was not confirmed to be linked to the attack. The incident drew attention to a separate vulnerability disclosed by Cosmos Labs in March 2026 concerning the ICS20 precompile, which had caused an estimated $7 million loss on another EVM chain; MANTRA participated in the earlier investigation but has not indicated that the August incident used the same flaw. In June 2025 Inveniam Capital Partners announced a $20 million strategic investment in MANTRA and its affiliated entities. The network focuses on tokenized real‑world assets and continues its institutional partnerships.
