0x API mainnet forking Hardhat example

This project demonstrates how you can use Hardhat to fork the Ethereum mainnet and run tests on your private fork using quotes from using production Ethereum 0x API.

Getting started

1. Clone the repo, and then run npm install.
2. Copy .env.example to .env and add your own RPC_URL
3. The example test is located in test/index.ts and can be executed with npx hardhat test

After running npx hardhat test you should see an output similar to this, confirming that your mainnet quote was successfully executed on your private fork
