Get Started

For quick installation of the contract ABIs:

npm i @oceanprotocol/contracts

Usage via Ocean Libraries

The ocean.js and ocean.py libraries wrap contracts in JavaScript and Python respectively. They each have quickstart guides.

Network Deployments

You can use an existing deployment of Ocean contracts, or do your own deployment for testing. Let's review each.

Use existing deployments

Ocean contracts are deployed to Rinkeby, Ethereum mainnet, and maybe more. Here are details.

Do your own deployment

To deploy to a local testnet:

• In a separate terminal, start the testnet: ganache-cli
• In your main terminal, run: npm run deploy

Alternatively, to deploy to rinkeby testnet:

• In your main terminal:

export MNEMONIC='YOUR MNEMONIC SHOULD BE HERE'

# If you are using remote test or Etherejm mainnet using Infura
export INFURA_TOKEN='GET INFURA_TOKEN FROM INFURA PLATFORM' 

npm run deploy:rinkeby

After deployment, check out the ./artifacts/address.json file. It contains the addresses of the deployed contracts. It will have been updated for the network you deployed to (e.g. development).

Local Development

For local development of contracts, set up the development environment on your machine as follows.

As a prerequisite, you need:

• Node.js v12+
• npm

Clone the project and install all dependencies:

git clone [e-mail]:oceanprotocol/ocean-contracts.git
cd ocean-contracts/

# install packages
npm i

# to compile contracts
npm run compile

Testing

Run tests with

# for unit tests
npm run test:unit

# for test coverage
npm run test:cover

Code Linting

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

# to check lint issues
npm run lint

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

Documentation

You can generate documentation using solidity-docgen. Here's how:

npm run doc:generate
