@erc725/erc725.js

Allows to read, encode and decode data from ERC725Y compliant contracts using ERC725Y JSON schemas.

For more information see the Documentation.

Installation

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

npm install @erc725/erc725.js

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

Instantiation

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.

You can initialize 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

import { ERC725, ERC725JSONSchema } from '@erc725/erc725.js';

// Part of LSP3-Profile-Metadata Schema
