Before you choose

Requirements & limits

The repository is public, open source and not archived. It is licensed under GPL-3.0. The documented local workflow assumes Node.js version 10 or newer and Yarn.

  • The repository is specifically focused on Uniswap V2 core smart contracts rather than a general-purpose exchange application.
  • The documented workflow covers dependency installation, compilation and testing.
  • Ethereum, ERC-20, decentralized-exchange and smart-contract topics are identified in the repository metadata.
  • The available documentation does not cover deployment steps.

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

Set up and test the V2 Core contracts locally

Install the documented dependencies, compile the contracts and run the repository tests.

Before you start

  • Node.js version 10 or newer
  • Yarn

Steps

  1. Run yarn to install dependencies.

  2. Run yarn compile to compile the contracts.

  3. Run yarn test to run the tests.

Expected outcome

The documented local workflow installs dependencies, compiles the contracts and invokes the test suite.

Guide limitations

  • The documentation does not provide a deployment procedure.
  • The source does not document the test results or a specific runtime environment beyond Node.js version 10 or newer and Yarn.
