Coinbase Loses $300K in Token Fees Due to Smart Contract Flaw
Coinbase took a $300,000 hit after a misstep in how it interacted with decentralized exchange protocol 0x’s “swapper” contract. The error opened the door for MEV bots to quietly drain funds from one of its corporate wallets. Customer assets weren’t affected, but the incident is a reminder that even big-name exchanges can get caught out by DeFi quirks. Coinbase hasn’t shared exactly how it’ll patch things up, but eyes are on how it responds next.
