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

CoinFeed reported on May 21 that, 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, roughly 4.8 million times the legitimate supply of 208 million tokens. Furthermore, according to the DeFi community YAM, the attacker has already profited approximately 52.2 ETH (about $110,000). In response, MAP Protocol stated that the team is aware of the incident and is coordinating with external security partners to investigate and contain it. The bridge between MAPO ERC-20 and the MAPO mainnet has been suspended. Do not trade MAPO ERC-20 tokens on Uniswap at this time.
