Get Started

For local development of nevermined-contracts you can either use Docker, or setup the development environment on your machine.

Docker

The simplest way to get started with is using the Nevermined Tools, a docker compose application to run all the Nevermined stack.

Public Network development

For deploying in a public network check ReleaseProcess.md first.

Local development

As a pre-requisite, you need:

• Node.js
• yarn

Clone the project and install all dependencies:

git clone [email protected]:nevermined-io/contracts.git
cd contracts/

Install dependencies:

yarn

Compile the solidity contracts:

yarn compile

In a new terminal, launch an Ethereum RPC client, e.g. hardhat:

npx hardhat node --port 18545

Switch back to your other terminal and deploy the contracts:

yarn deploy:external

For redeployment run this instead

yarn clean
yarn compile
yarn deploy:external

Upgrade contracts [optional]:

yarn upgrade:external

Testing

Run tests with yarn test, e.g.:

yarn test test/unit/agreements/AgreementStoreManager.Test.js

Code Linting

Linting is setup for JavaScript with ESLint & Solidity with Ethlint.

Code style is enforced through the CI test process, builds will fail if there're any linting errors.

yarn lint

Networks

When Nevermined contracts are deployed into different networks, the ABIs referring to the specific version deployed are copied into the Artifacts repository.

You can find more information about the this into the Release Process documentation.

For contracts older to v3.x please see the Legacy Artifacts Repository.
