🎈 Thanks for your help improving the project! We are so happy to have you!
No contribution is too small and all contributions are valued.
There are plenty of ways to contribute, in particular we appreciate support in the following areas:
- Reporting issues. For security issues see Security policy.
- Fixing and responding to existing issues. You can start off with those tagged "good first issue" which are meant as introductory issues for external contributors.
- Join Kroma Discord and answer the questions.
- Get involved in the protocol design process by proposing changes or new features or write parts of the spec yourself in the specs.
Note that we have a Code of Conduct, please follow it in all your interactions with the project.
🚨 Before making any non-trivial change, please first open an issue describing the change to solicit feedback and guidance. This will increase the likelihood of the PR getting merged.
In general, the smaller the diff the easier it will be for us to review quickly.
In order to contribute, fork the appropriate branch, for non-breaking changes to production that is dev
and
for the next release that is normally release/X.X.X
branch. (TODO: add a document about branching strategy)
Additionally, if you are writing a new feature, please ensure you add appropriate test cases.
Follow the Development Quick Start to set up your local development environment.
We recommend using the Conventional Commits format on commit messages.
Unless your PR is ready for immediate review and merging, please mark it as 'draft' (or simply do not open a PR yet).
Bonus: Add comments to the diff under the "Files Changed" tab on the PR page to clarify any sections where you think we might have questions about the approach taken.
We aim to provide a meaningful response to all PRs and issues from external contributors within 2 business days.
We use changesets to manage releases of our various packages.
You must include a changeset
file in your PR when making a change that would require a new package release.
Adding a changeset
file is easy:
- Navigate to the root of the monorepo.
- Run
yarn changeset
. You'll be prompted to select packages to include in the changeset. Use the arrow keys to move the cursor up and down, hit thespacebar
to select a package, and hitenter
to confirm your selection. Select all packages that require a new release as a result of your PR. - Once you hit
enter
you'll be prompted to decide whether your selected packages need amajor
,minor
, orpatch
release. We follow the Semantic Versioning scheme. Please avoid usingmajor
releases for any packages that are still in version0.y.z
. - Commit your changeset and push it into your PR. The changeset bot will notice your changeset file and leave a little comment to this effect on GitHub.
- Voilà, c'est fini!
We use the git rebase
command to keep our commit history tidy.
Rebasing is an easy way to make sure that each PR includes a series of clean commits with descriptive commit messages
See this tutorial for a detailed explanation of git rebase
and how you should use it to maintain a clean commit history.
You'll need the following:
Clone the repository and open it:
> git clone [email protected]:kroma-network/kroma.git
> cd kroma
Install node v16.16.0 with nvm
> nvm use
> yarn
foundry is used for some smart contract development in the monorepo. It is required to build the TypeScript packages and compile the smart contracts. Install foundry here.
To build all of the TypeScript packages, run:
> yarn build
Packages compiled when on one branch may not be compatible with packages on a different branch. You should recompile all packages whenever you move from one branch to another. Use the above commands to recompile the packages.
Before running tests: follow the above instructions to get everything built.
Run unit tests for all packages in parallel via:
> yarn test
To run unit tests for a specific package:
> cd packages/package-to-test
> yarn test
