Map Protocol/Butter Network cross-chain bridge was attacked on Ethereum and BSC, resulting in a loss of approximately $110,000

According to Blockaid monitoring, the Map Protocol/Butter Network cross-chain bridge has been attacked on Ethereum and BSC. The attacker tricked the Butter Bridge V3.1 contract into directly minting approximately 100 trillion MAPO tokens to a newly created EOA address, which is about 480 million times the legitimate supply of 208 million tokens. Additionally, according to DeFi community YAM monitoring, the attacker has currently profited approximately 52.2 ETH (about $110,000). In response, MAP Protocol stated that the team is aware of the situation and is coordinating with external security partners to investigate and contain the issue. The bridging between MAPO ERC-20 and MAPO mainnet has been suspended. Please do not trade MAPO ERC-20 tokens on Uniswap at this time. During the event mitigation period, the liquidity pool remains at risk.

Butter Network responded that ButterSwap has been suspended, and the team is coordinating with external security partners for the investigation. Pending transactions will be processed after security is restored. User funds are not at risk, and all affected transactions will be fully processed after recovery.
