OpenZeppelin cross-chain environments

:warning: :wrench: This repository is experimental and may not be actively maintained in the future.

This repository is an effort toward improving the testing of cross-chain contracts and applications. It contains ressources to easily spin-up local test environments.

For now only optimism is supported. We hope to soon offer test frameworks for other scalability solutions.

Optimism

Start the environment

npm run optimism:start

Check status

The optimism containers need to go through a configuration step. It takes some time (1~2 min) before the environment is ready for running tests. You can check the current status or activelly wait for it to be ready using the following commands:

npm run optimism:check

npm run optimism:wait

Stop the environment

npm run optimism:start

Upcoming networks

We hope to soon include support for:

• Arbitrum
• Gnosis Chain
• Loopring
• Polygon
• zkSync

If you are an expert in any of these, external contributions to expand this repository are welcome!
