permit2-matcha

A headless prototype of how Matcha will use the 0x API & permit2 smart contracts to swap erc20 tokens.

The purpose of this repo is to serve as a guide when integrating the api/v2/permit2 standard transaction flow into Matcha. If successful, the script will grant the permit2 contract on mainnet an infinite allowance to transfer your WETH tokens.

Requirements

• Bun (v1.1.0+)
• An Ethereum private key

Usage

1. Create an .env file:

cp .env.example .env

2. Add your Etheruem private keys & 0x production API key to it.
3. Install dependencies

bun install

4. Run the script

bun run start
