ModuleKit

A development kit for building and testing smart account modules.

ModuleKit allows you to:

• Easily build smart account modules with interfaces for:
  • Validators
  • Executors
  • Hooks
• Unit test your modules using a dedicated helper library
• Integration test your modules using different modular ERC-4337 accounts and a helper library that abstracts away the complexity

In-depth documentation is available at docs.rhinestone.wtf.

The ModuleKit is in active development and is subject to breaking changes. If you spot a bug, please take out an issue and we will fix it as soon as we can.
