Summary

Optimism is rewarding builders, from a pool of 5,000 OP, who help grow the Supersim repo!

Supersim is an open source tool: The Local Multi-L2 Development Environment.

Experiment with Superchain Interop using Supersim, the lightweight tool to simulate the Superchain locally.

With Supersim, you can simulate entire cross-chain application flows, intricate message passing infrastructure, and OP Stack specific logic with one command.

Locally observe cross-chain interactions and iterate on multi-chain apps.

How it works

Merge PRs to address issues in the Supersim repository to earn rewards.

Earn 200 OP for a PR addressing an issue labeled as good first issue and/or help wanted.

For those more adventurous, earn 200 to 500 OP for merging a PR addressing a new issue. Create an issue in the repository detailing your proposed contribution before starting work. The contribution must be substantial, more than typos/syntax fixes. OP will respond to new issues and then let you know if a PR would be accepted! Here are high priority additional desired features:

• Additional examples (see /examples/tic-tac-toe) showcasing projects to build with Supersim
• Improvements and additions to documentation
• Additional integrations (see /integrations/hyperlane) showcasing services that can be run locally alongside Supersim to provide an even better local development experience
