Flashloan

Now, you’ll create a Flash Loan Contract that enables users to borrow funds instantly and repay them within a single transaction. Divided into three tasks, you’ll learn how to build flash loans, execute arbitrage strategies between DEXs, and aggregate loans from multiple providers (Aave, Uniswap, and your contract).

Flashloan MVP

Create a flash-loan contract that:

• Lets users deposit and withdraw any type of funds (tokens and ETH)
• Has a flashLoan(address[] _tokens, uint256[] _amounts) that allows anyone to get the funds and repay them with a 0.001% extra

Arbitrage Test

Flashloan Aggregator

Create another contract that flash-loans from multiple flash-loan providers.

i.e. flash-loan 100M (70M from uniswapV2, 20M from aave, 10M from your flash-loan contract)
