Solidity Debugger for Visual Studio Code

Simbolik is a Solidity debugger for Foundry projects. It allows you to step through your Solidity code line by line, set breakpoints and inspect variables.

Quick Start

On first use Simbolik may ask for GitHub access. Alternatively, you can provide a Simbolik API key, read more.

Simbolik follows a zero-configuration approach where possible and falls back to configuration-as-code where needed. For simple smart contracts, you can start debugging with just a single click on the ▷ Debug-button.

For complex smart contracts, you set up your debugging session similarly to a Foundry unit test: You first define a setUp function to initialize your contracts, and then provide a test function. If the test function is public and does not have parameters, the ▷ Debug-button shows up, read more.
