Foundry is a powerful and comprehensive tool for building, testing, and deploying smart contracts. It's a popular choice for developers of decentralized applications.
The installation process is simple and straightforward. Use the provided curl command to download and execute the Foundry installer script.
curl -L https://foundry.paradigm.xyz | bash
Foundry provides a simple command to initialize a new project with basic configuration and folder structure.
Initializes a new Foundry project in the current directory.
Overwrites an existing project if one already exists in the current directory.
Foundry uses a configuration file, foundry.toml, to customize the project's behavior, such as setting the Solidity compiler version and specifying formatting rules.
\[profile.default]
solc_version = "0.8.17"
Install Solidity extension
Add settings to VS Code
Run command to automatically format code
Forge provides a convenient script for deploying contracts to a blockchain network. This approach simplifies the deployment process and ensures consistent execution.
Deploy a contract using a forge script
Specifies the URL of the blockchain network to connect to
Enables interactive mode for confirmations and inputs during deployment
Foundry scripts are powerful tools for automating interactions with smart contracts, enabling tasks like deployment, testing, and data manipulation.
Import forge-std for essential functions and utilities
Use vm.startBroadcast() and vm.stopBroadcast() to manage transaction execution
Run scripts using the forge script command with options for specifying the network, broadcasting transactions, and providing private keys
Foundry offers a command-line interface (CLI) for interacting with deployed contracts, allowing for sending transactions and retrieving data.
Sends a transaction to a contract function
Executes a contract function without sending a transaction
Provides tools for data conversion and manipulation
Foundry automates the compilation process, ensuring that the Solidity code is compiled into bytecode ready for deployment on the blockchain.
Compiles all Solidity contracts in the project
Foundry provides a comprehensive testing framework that simplifies the process of writing and executing tests for smart contracts, enhancing code quality and reliability.
Create test files in the test directory, inheriting from the Test contract
Use setup, success, and fail tests, as well as event checks
Utilize functions like vm.prank(), vm.deal(), and vm.warp() for advanced testing scenarios
Use the forge test command with various options for filtering tests, controlling verbosity, and enabling advanced features
Foundry integrates well with popular third-party libraries, simplifying development and enabling developers to leverage pre-built components for common functionalities.
