What problem it solves

Ethereum application development requires tooling to build, test and deploy Solidity contracts, interact with EVM chains, and run a local development node. Foundry groups these capabilities into a set of separate tools so a developer can cover the whole workflow without stitching together unrelated utilities.

Key features

• Forge for contract development — Forge is the tool for building, testing, fuzzing, debugging and deploying Solidity contracts, including a project initializer and a language server mode.

  Source: crates/forge, README

• Cast for chain interaction — Cast interacts with EVM smart contracts, sends transactions and fetches chain data, including balance and block-number queries against a live RPC endpoint.

  Source: crates/cast, README

• Anvil local development node — Anvil is a local Ethereum development node that can fork a remote chain, so contracts can be exercised against mainnet state locally.

  Source: README, crates/anvil, crates/anvil/core

• Chisel Solidity REPL — Chisel provides a Solidity REPL for quick interaction with the language, shipped as its own crate within the workspace.

  Source: README, crates/chisel

• Solidity editor integration — The `forge lsp` command opens a Solidity project in a VS Code Extension Development Host with the bundled Solidity extension, or serves other editors over stdio.

Quick start

Copied verbatim from the project's README.

curl -L https://foundry.paradigm.xyz | bash
foundryup

forge init counter && cd counter
forge build
forge test

anvil --fork-url https://eth.merkle.io

Who it may suit

Inference: may suit Solidity developers who want a single toolkit for contract testing, chain interaction and local node work, and contributors looking to work on a multi-crate Rust workspace.

Topics to discuss

• How should the division of responsibilities between Forge, Cast, Anvil and Chisel evolve as new Ethereum tooling needs appear?

• What workflows would you most like the language server and linting integration to cover beyond the current forge lsp setup?

• Which areas of the workspace would you prioritise for new contributors, and what documentation gaps should be closed first?
