Map Protocol token plummets 96% after a quadrillion token mint exploit

Map Protocol's native token, MAPO, experienced a 96% price drop following an exploit on the Butter Network cross-chain bridge. An attacker leveraged a Solidity contract vulnerability to mint a quadrillion tokens, far exceeding the legitimate supply. The perpetrator dumped approximately one billion tokens into Uniswap liquidity pools, extracting about $180,000 in ETH. In response, Map Protocol paused its mainnet and initiated a migration plan, stating that tokens held by the attacker will be invalidated in future asset snapshots. No private keys were compromised; the exploit was attributed to a failure in validating retry messages within the bridge protocol.
