A set of challenges to hack implementations of DeFi in Ethereum.
Created by @tinchoabbate
There's a lending pool offering quite expensive flash loans of Ether, which has 1000 ETH in balance.
You also see that a user has deployed a contract with 10 ETH in balance, capable of interacting with the lending pool and receiveing flash loans of ETH.
Drain all ETH funds from the user's contract. Doing it in a single transaction is a big plus ;)
