Testing 1inch swaps

This project demonstrates how to test 1inch swaps locally using ethers v6 in a basic Hardhat project.

Overview

This project contains a single script that will do the following on a local fork of Mainnet:

• Move WETH from a large holder to a local wallet
• Approve the 1inch v6 router to spend the local wallet's WETH
• Swap WETH for USDC through the 1inch v6 router

Setup

Install the project

npm install

Run a local fork of Mainnet from your terminal (Infura or Alchemy are good RPC options)

npx hardhat node --fork <mainnet_rpc_url>

With your local fork running, open up a second terminal and run the following from the root directory of the project:

npx hardhat run scripts/1inchSwap.js --network localhost

This second terminal will connect to your local hardhat fork of Mainnet and simulate the swap
