erc3156's Introduction

ERC20 Flash

This project is the reference implementation the ERC 3156 Flash Loan standard.

This project also implements ERC-3156 wrappers for the flash loan functionality of dYdX, Aave, Uniswap and Yield.

Contracts deployed

Kovan

Use FlashBorrower to kick the tires. You can give to the flashBorrow function the address of an ERC3156 compliant lender (such as any of the wrappers in this repo), the address of a supported ERC20 token (which for wrappers depends on the underlying lender such as Aave) and a loan value. Upon execution a flash loan will happen, which you can examine in etherscan.io or tenderly.co. You will need to have transferred to FlashBorrower enough of the ERC20 being borrowed beforehand to pay for the fees.

Tested currencies

The flash loans have been tested with the ERC20 tokens below, but should work for any tokens that the underlying lenders make available.
