Foundry

Foundry is a smart contract development toolchain.

With Foundry you can manage your dependencies, compile your project, run tests, deploy smart contracts, and interact with the chain from the command-line and via Solidity scripts.

Check out the Foundry Book to get started with using Foundry with Base.

Using Foundry with Base

Foundry supports Base out-of-the-box.

Just provide the Base RPC URL and Chain ID when deploying and verifying your contracts.
