Foundry on Rootstock

Foundry is a smart contract development toolchain, and user-friendly development environment for writing and testing smart contracts in Solidity. It manages dependencies, compiles, run tests, deploy contracts and allows for interaction with EVM-compatible chains using a command-line tool called Forge.

Why use Foundry?

Forge is ideal for advanced smart contract analysis, auditing, and for fast execution of smart contract tests.

hardhat-foundry plugin

Use the hardhat-foundry plugin to have your Foundry project work alongside Hardhat.

Here are some reason why you may prefer Foundry:

1. Local Networks: It provides a local blockchain environment using the anvil tool, allowing developers to deploy contracts, run tests, and debug code. It can also be used to fork other EVM compatible networks.

2. Advanced Testing: Forge comes with a number of advanced testing methods including:

   • Fuzz testing
   • Invariant testing
   • Differential testing
   • Symbolic Execution
   • Mutation Testing

3. Advanced Debugging: Forge allows for advanced debugging using an interactive debugger.

The debugger terminal is divided into four quadrants:

• Quadrant 1
  • The opcodes in the debugging session, with the current opcode highlighted. Additionally, the address of the current account, the program counter and the accumulated gas usage is also displayed.
• Quadrant 2
  • The current stack, as well as the size of the stack
• Quadrant 3
  • The source view.
• Quadrant 4
  • The current memory of the EVM.
