ME News, May 21 (UTC+8), according to Blockaid monitoring, the Map Protocol/Butter Network cross-chain bridge was attacked on Ethereum and BSC. The attacker tricked the Butter Bridge V3.1 contract into directly minting approximately 1000 trillion MAPO tokens to a newly created EOA address, about 4.8 million times the legitimate supply of 208 million tokens. Additionally, according to DeFi community YAM monitoring, the attacker has so far profited about 52.2 ETH (approximately $110k). In response, MAP Protocol stated that the team has been informed of the incident and is coordinating with external security partners for investigation and containment. The bridge between MAPO ERC-20 and the MAPO mainnet has been suspended. Please do not trade MAPO ERC-20 tokens on Uniswap for now. There is still risk to the liquidity pool during mitigation measures. Butter Network responded that ButterSwap has been paused, and the team is coordinating with external security partners for investigation. Pending transactions will be processed after safe recovery. User funds are not at risk, and all affected transactions will be fully processed after recovery. (Source: PANews)
