@erc725/erc725.js

Allows for interacting with ERC725Y compliant contracts on an EVM blockchain.

For more information see the Documentation.

Installation

npm install @erc725/erc725.js

import { ERC725 } from '@erc725/erc725.js';
// Or alternatively the default export
import ERC725 from '@erc725/erc725.js';

If you install it on the backend side, you may need to also install isomorphic-fetch.

Instantiation

You need to initialise the ERC725 object with a schema, a contract address, and an RPC URL.

const address = '0x0Dc07C77985fE31996Ed612F568eb441afe5768D';
const RPC_URL = 'https://rpc.testnet.lukso.network';
const config = {
  ipfsGateway: 'https://YOUR-IPFS-GATEWAY/ipfs/',
  gas: 20_000_000, // optional, default is 1_000_000
};

TypeScript

If you are using ES6 import statements in Node.js, make sure your file has a .mjs extension, or that your project is set up to support ES6 modules.
