Practical overview

When it fits

Use it when developing or integrating Solidity contracts for arbitration and dispute resolution, or when you need the repository's documented compile, lint and test scripts.

Who it is for

  • Solidity developers working on dispute-resolution applications.
  • Developers building arbitrable contracts connected to an arbitrator contract.
  • Teams creating test suites for applications that integrate Kleros contracts.

Documented uses

  • Install repository dependencies and compile the core contracts.
  • Lint or format Solidity and JavaScript project files.
  • Run the repository's Truffle tests.
  • Use the contracts as a basis for arbitration-related application and integration development.
Before you choose

Requirements & limits

The repository is public and MIT-licensed.

  • The documented setup uses Yarn, and the test command invokes Truffle tests.
  • The README points to ERC-792 documentation for developing arbitrable and arbitrator contracts.
  • The repository documents contract compilation and development scripts, not a complete deployment or arbitration-operation procedure.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install dependencies and compile Kleros contracts

Prepare the repository dependencies and compile its contracts using the documented Yarn scripts.

Before you start

  • A local Git client to clone the repository.
  • Yarn.

Steps

  1. Clone https://github.com/kleros/kleros.

  2. From the repository, run yarn to install dependencies.

  3. Run yarn run build to compile the contracts.

Expected outcome

The documented build command compiles the contracts.

Guide limitations

  • This procedure covers dependency installation and compilation only; it does not document deployment.

Run the repository's documented Truffle tests

Invoke the project's test suite after setting up its dependencies.

Before you start

  • A cloned Kleros repository.
  • Dependencies installed with yarn.

Steps

  1. Run yarn in the repository to install dependencies.

  2. Run yarn test to invoke the Truffle tests.

Expected outcome

The documented test command invokes the repository's Truffle test suite.

Guide limitations

  • The instructions do not describe test coverage, individual test cases or deployment.
