Meter.io has suspended bridge operations and urged users to stop transacting after an attacker exploited a block-validation vulnerability on its mainnet, minting approximately $2.3 million of unbacked wrapped MTRG on BNB Chain. BlockAid said some of the tokens were sold through PancakeSwap and that the initial phase involved about two transactions. Meter said the attack began on September 23 at 18:14 and also enabled the creation of worthless MTR and MTRG, with some proceeds transferred to other networks. Transactions after block 100731417 may not qualify for recovery, while the asset-recovery method remains undecided. The team is coordinating with exchanges, security firms and law enforcement to track and freeze funds, and has offered a 10% reward if the attacker returns the assets within 72 hours. The incident follows a separate 2022 Meter Passport exploit that Meter estimated caused about $4.25 million in losses across four networks.
