According to Hyperbridge's official disclosure, the loss from the Token Gateway vulnerability incident has been revised from an initial estimate of $237,000 to approximately $2.5 million, with the increase mainly coming from losses in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum.

The attacker extracted about 245 ETH from the relevant contracts and then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOT and selling them into a thinly traded market. Currently, some of the stolen funds have been traced on-chain to Binance, and Hyperbridge is collaborating with Binance's compliance team and law enforcement agencies for an investigation.

Native DOT of Polkadot and products like Intent Gateway are unaffected, while the Token Gateway and the bridged DOT contracts on the four affected EVM chains remain suspended. The MMR verification logic patch is undergoing external audit, and the bridging functionality will be restored after the audit is completed.
