Live Coding Session

Talkat ETHDenver 2021 · 2021-02-05..02-12· [ethereum, smart-contracts]
slides:none on file

Live coding walks through Aave v2 flash loans with a live transaction trace (a 25,760 USDC flash loan), shows the flow: lendingPool.flashLoan → receiver contract → Uniswap swap → repay, and explains WETH unwrap and ERC20 approvals. Demo code uses Tenderly and Remix for debugging and deployment, plus a GitHub repo and a fake-arbitrage contract funded with 0.2 ETH bounty that returns principal+9 bps. The demo transaction executes successfully and the exercise invites reproducing or exploiting a deliberate backdoor to win the 0.2 ETH.
