Migration Notice
Please note the Chainbridge-Core repo will be migrated to Sygma-Core as part of ongoing work to update the codebase. See Sygma to learn more.
Chainbridge-Core was born from and built to improve the maintainability and modularity of the existing version of ChainBridge. The fundamental distinction between the two is that Chainbridge-Core is more of a framework rather than a stand-alone application.
Project still in deep beta
Table of Contents
Installation
Refer to the installation guide for assistance with installing the ChainBridge binary.
Usage
Since ChainBridge-Core is a library it will require writing some code to get it running.
You can find some examples here.
The deployment scripts of this version uses the V2.1.3 solidity scripts from https://github.com/ChainSafe/sygma-solidity/tree/v2.1.3
Local Setup
This section allows developers with a way to quickly and with minimal effort stand-up a local development environment in order to test out functionality of the ChainBridge.
Example
The example developer setup can be run with the make example command which will create a 3 relayer setup with 2 EVM networks with already preconfigured ERC20, ERC721 and Generic handlers and appropriate assets.
^ this command will execute a shell script that contains instructions for running two EVM chains via Docker (docker-compose). Note: this entire process will likely take a few minutes to run.
You can also review our Local Setup Guide for a more detailed example of setting up a local development environment manually.
Contributing
Chainbridge-core is a open project and welcomes contributions of all kinds: code, docs, and more. If you wish to submit more complex changes, please check up with the core devs first on our Discord Server (look for CHAINBRIDGE category) or submit an issue on the repo to ensure those changes are in line with the general philoshophy of the project or get some early feedback.
When implementing a change:
- Adhere to the standard Go formatting guidelines, e.g. Effective Go. Run
go fmt. - Stick to the idioms and patterns used in the codebase. Familiar-looking code has a higher chance of being accepted than eerie code. Pay attention to commonly used variable and parameter names, avoidance of naked returns, error handling patterns, etc.
- Comments: follow the advice on the Commentary section of Effective Go.
- Minimize code churn. Modify only what is strictly necessary. Well-encapsulated changesets will get a quicker response from maintainers.
- Lint your code with
golangci-lint(CI will reject your PR if unlinted). - Add tests.
- Title the PR in a meaningful way and describe the rationale and the thought process in the PR description.
- Write clean, thoughtful, and detailed commit messages.
If change entails an update that needs to be documented, please submit a PR to chainbridge-docs repo.
Submiting a PR
