Incident Overview
The WAX Multi-Chain Bridge (spanning WAX, Solana, and Ethereum) was exploited due to a smart contract logic flaw. The eth.token::withdraw function failed to enforce max_fee ≥ 0 before debiting; the attacker set a negative max_fee equal to -quantity, zeroing the debit while still generating a full withdrawal log and bridge records. This triggered corresponding asset releases on Solana and Ethereum, resulting in a loss of approximately $90,500. Officials confirmed the issue was limited to a bridge contract (stablecoins affected; WAXP and the main chain unaffected) and paused bridge processing.
