just one more AA EIP bro i swear just one more AA EIP and that will fix wallets no. instead the Ethereum ecosystem must make some decisions for its wallet users, enforce them in an EIP (instead of "infinite garden, anyone can build anything") and build actually good UX / DX.

⛑ $512K rescued by Defimon after infinite approvals were granted to @squidrouter multicall The SquidMulticall contract's run() function allows anyone to execute arbitrary external calls with no access control. A wallet 0xacc0 mistakenly approved the multicall contract instead of the router contract and did it across multiple chains. It didn't take a long time before first attack - a MEV-bot called run() with a crafted Call struct that executed transferFrom() on the WETH contract, transferring just 1 WETH from a victim. In fact the victim user had around $800K approved to the mulitcall contract on various chains. After we detected the first attack our whitehat bot identified the vulnerable cross-chain approvals and managed to rescue around $512K. We contacted the person via Blockscan chat and returned all the rescued funds. We learnt that it was an operational mistake: "we were supposed to only approve to the Squid router address". Although some funds were lost, 0xacc0 was happy that the majority of the funds was rescued! First attack: bscscan.com/tx/0x81d0c429e… Victim: bscscan.com/address/0xaCc0… SquidMulticall: bscscan.com/address/0xaD6C… Rescued funds consolidation address: debank.com/profile/0xF50D…

I've seen this somewhere before 👀 Jokes aside, I do think hub/spoke architecture is the right direction for a lending protocol to capture wide range of existing and future use-cases and access more granular risk controls. Good call.
