🏗 Installation

For quick installation of the contract ABIs:

Javascript/Typescript

yarn add @oceanprotocol/contracts

Python

pip3 install ocean-contracts

⚙️ Usage

By default, Python does not support importing json files directly, so it is recommended to use json-sempai package in order to automatically importing ABIs/json artifacts.

pip3 install json-sempai
# install the ocean-contracts package.

from jsonsempai import magic
from artifacts import address
address.mainnet
{'DTFactory': '0x57317f97E9EA49eBd19f7c9bB7c180b8cDcbDeB9', 'BFactory': '0xbe0083053744ECb871510C88dC0f6b77Da162706', 'FixedRateExchange': '0x608d05214E42722B94a54cF6114d4840FCfF84e1', 'Metadata': '0x1a4b70d8c9DcA47cD6D0Fb3c52BB8634CA1C0Fdf', 'Ocean': '0x967da4048cD07aB37855c090aAF366e4ce1b9F48'}

🏄 Quickstart

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, deploy locally, or deploy to a remote network. Let's review each.

Use existing deployments

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

Deploy Locally (Ganache)

• In a separate terminal, start the testnet: ganache-cli
• In your main terminal, run: yarn deploy
• Confirm: are "development" entries updated in addresses file ./artifacts/address.json?

Deploy to Remote (e.g. Rinkeby)

• 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'

yarn deploy:rinkeby

• Confirm: are "rinkeby" entries updated in addresses file ./artifacts/address.json?

🦑 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+
• yarn

Clone the project and install all dependencies:

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

# install packages
yarn

# to compile contracts
yarn compile

✨ Code Style

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

# to check lint issues
yarn lint

👩‍🔬 Testing

In a separate console:

ganache-cli

In main console:

# for unit tests
yarn test:unit

# for test coverage
yarn test:cover

Code style is enforced through the CI test process. Builds will fail if there are linting errors.
