Foundry

Foundry is a comprehensive smart contract development toolchain that provides everything needed for Ethereum development. The framework consists of three core tools that work seamlessly together.

Forge handles the complete development lifecycle - building, testing, debugging, deploying, and verifying smart contracts. It manages dependencies automatically and provides robust testing capabilities for contract validation.

Anvil serves as your local development node that fully complies with Ethereum specifications. It creates a fresh blockchain environment with pre-funded accounts for testing, supports mainnet forking for realistic testing scenarios, and allows state loading and dumping for development workflows.

Cast functions as a command-line interface for blockchain interaction. It enables direct contract function calls, transaction sending, and JSON-RPC method execution without requiring additional tools or interfaces.

Key features include:

• Fast compilation and testing with optimized performance
• Dependency management for seamless project organization
• Local blockchain simulation with Anvil for isolated testing
• Command-line blockchain interaction via Cast
• Mainnet forking capabilities for realistic development environments
• Contract verification and deployment automation

The toolkit is designed for developers who prefer command-line workflows and need reliable, fast tools for smart contract development on Ethereum and EVM-compatible networks.
