On January 8th, Truebit Protocol suffered a critical exploit through an integer overflow vulnerability in its Purchase contract. The attacker leveraged the flaw to mint TRU tokens at nearly zero cost, subsequently draining approximately 8,535 ETH (roughly $26.44M) from the protocol. Security researchers pinpointed the root cause as improper overflow protection in the contract logic. This incident underscores the importance of rigorous code audits and overflow safeguards in smart contract development, especially for protocols handling substantial value. The affected users and the broader community are monitoring the situation closely as details continue to emerge.
