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.
Deploying a smart contract
forge create ... --rpc-url=https://goerli.base.org/
Verifying a smart contract
forge verify-contract ... --chain-id 84531
