TREE NEWS update: An MEV bot called “Yoink” front-ran an attacker attempting to exploit a custom Safe module and captured the stolen rsETH, valued at $7.7 million, before Kelp temporarily froze the receiving address. The bot intercepted the funds ahead of the exploiter, and the receiving address was subsequently frozen by Kelp.
MEV Bot Front-Runs Exploiter, Captures $7.7M in rsETH Before Kelp Freezes Address
This episode highlights how MEV infrastructure can act as an unintended circuit breaker during live exploits, with a bot effectively seizing funds faster than the protocol's own response. The outcome also shows that freezing a receiving address is a blunt, reactive tool: it can lock assets, but it does not resolve who ultimately holds or controls them. The open question is whether such front-running becomes a routine feature of exploit response, and how protocols weigh temporary freezes against the operational and legal complications they create.
