FAQPage Schema

How do I build and test Solidity smart contracts with Foundry?▼

Foundry provides Forge for building and testing Solidity contracts. Initialize a project with `forge init`, write tests in `*.t.sol` files, then run `forge test` to execute unit, fuzz, and invariant tests with deterministic, fast execution.

Can I deploy and verify smart contracts using Foundry scripts?▼

Yes. Foundry supports script-driven deployments through `*.s.sol` files and `forge script` commands. Execute scripts with `--broadcast` to deploy contracts on-chain and verify them automatically.

What's the difference between Forge, Cast, and Anvil in Foundry?▼

Forge compiles and tests Solidity contracts. Cast interacts with on-chain data and sends transactions for debugging. Anvil provides a local EVM node for testing and development without external dependencies.

How do I configure Foundry projects and manage dependencies?▼

Foundry uses `foundry.toml` for project configuration, including compiler settings, dependencies, and test parameters. This replaces traditional configuration files and integrates all project setup in one place.

Do I need prior experience with Solidity to use Foundry?▼

Basic Solidity knowledge is helpful but not required. Foundry's documentation and test patterns guide you through contract development. Start with `forge init` and examples to learn incrementally.

Can Foundry test contracts against live Ethereum state?▼

Yes. Forge supports fork testing, allowing you to run tests against mainnet or testnet state. This validates contract behavior in realistic network conditions without deploying to live networks.
