Insane story... Some guy tried to buy $50M of $AAVE on his phone, like 3% of the total supply, tapped through warnings, ended up with only $40K of AAVE. Block builder made off with ~$40M, Aave refunds $600K of fees. Net result, AAVE token is down. 💀

I'm not following the article. What exactly are they claiming here? It seems like they claim that the UI stated a number 1% higher than what the user got. Who cares? Main thing it seems is that there were no other solvers competing on this order, akin to the MakerDAO COVID auctions. That's bad, and demands explanation. But even if the optimal route was used, there was only $7M worth of AAVE in standing liquidity anywhere. So instead of -99.8%, their swap would result in -86%. Clearly whatever happened here is multiple levels of confusing. Even the most robust routing algorithm should have shown this user that any trade of this kind would be catastrophically bad for them. I'm sure all of us have seen this kind of thing many, many times testing numbers in a UI and seeing what happens when the liquidity is just absent.

Whoops, Titan
