Setup

Installation and System Requirements

To install, run the following:

npm install @celo/contractkit
// or
yarn add @celo/contractkit

You will need node version 10.0.0 or higher.

Initializing the Kit

To start working with ContractKit you need a kit instance and a valid net to connect with. In this example will use alfajores (you can read more about it here)

import { newKit } from '@celo/contractkit'
const kit = newKit('https://alfajores-forno.celo-testnet.org')

Go to the page about Forno for details about different connection types and network endpoints.

Initialize the Kit with your own node

If you are hosting your own node (you can follow this guide to run one) you can connect our ContractKit to it.

import { newKit } from '@celo/contractkit'
// define localUrl and port with the ones of your node
const kit = newKit(`${localUrl}:${port}`)

Same as Web3 we support WebSockets, RPC and connecting via IPC. For this last one you will have to initialize the kit with an instances of Web3 that has a valid IPC Provider

import Web3 from 'web3'
import { newKitFromWeb3 } from '@celo/contractkit'
const web3Instance: Web3 = new Web3(new Web3.providers.IpcProvider('/Users/myuser/Library/CeloNode/geth.ipc', net))
const kit = newKitFromWeb3(web3Instance)
