About

This repository provides instructions on how to deploy your smart contract to the WVM testnet using Forge. It focuses on the Arweave precompiles (0x17, 0x18) to provide a tutorial on how to read and write data to Arweave from the EVM smart contract interface.

Example deploy address for Merged Precompiles 0x69420

0x9fb0F63B569f9FD8718Bbb2856a4b6F2458C2d70

Prerequisites

• Foundry installed
• Your smart contract ready for deployment
