MUI Metablockchain SDK

JS SDK to interface with MetaMUI Metablockchain node.

Install

npm install mui-metablockchain-sdk

Usage

Network options

The best practice is to first create a websocket connection to the network you intend to connect with and then pass this object to all function calls. The available network options are local, dev, testnet, mainnet If no network is specified, the functions default to either dev or local. In future when multiple nodes are being hosted, the user will have to option to pass url of the node itself.

Example

• Create a DID and write on chain

const { connection, did, config } = require('mui-metablockchain-sdk');
const NETWORK = "dev";

async function create_new_did(){

const mnemonic = "//Bob";
const new_did = "sample";

// create the DID object
let did_obj = await did.generateDID(mnemonic, new_did, "");

//Use the validator account to sign did operation
const keyring = await config.initKeyring();
const sig_key_pair = await keyring.addFromUri('//Alice');

let provider = await connection.buildConnection(NETWORK);
let tx_hash = await did.storeDIDOnChain(did_obj, sig_key_pair, provider);

return tx_hash;
}
