Coinbase $300k MEV Loss via 0x Swapper — Isolated but Signals Integration Risk

I note that Coinbase lost about $300,000 in token transaction fees to MEV bots after an incorrect interaction with a 0x “swapper” contract caused by a DEX wallet configuration change.

I view this as an isolated operational issue: Coinbase’s CSO confirmed the token approval was revoked, funds moved to a new wallet, and user funds were not affected.

Though the immediate impact appears contained, the incident highlights integration and configuration risks for exchanges and protocols interacting with DEX infrastructure — it’s worth monitoring 0x and Coinbase for follow-up fixes and any similar occurrences.
