Summary

Truebit is an Ethereum-based protocol for verifiable off-chain computation, co-founded by mathematician Jason Teutsch and Solidity creator Christian Reitwiessner. On January 8, 2026, an integer overflow vulnerability in a five-year-old, closed-source legacy Purchase contract was exploited, draining 8,535 ETH (approximately $26.44 million) and causing the TRU token to collapse by over 99.9%; the attacker subsequently laundered all stolen funds through Tornado Cash.
