Hyperbridge announced on its X platform that the losses from the Token Gateway vulnerability incident on April 13th have been revised from the initial estimate of $237,000 to approximately $2.5 million. The increase primarily stems from losses in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum. The attackers extracted approximately 245 ETH from the relevant contracts and then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOTs and selling them. Some of the stolen funds have been traced to Binance, and Hyperbridge is collaborating with Binance's compliance team and law enforcement agencies on the investigation. Polkadot's native DOT and Intent Gateway products are unaffected, while the Token Gateway and bridged DOT contracts on the four affected EVM chains remain suspended. The MMR verification logic patch is currently undergoing external auditing.
