TypeScript

import 'dotenv/config';
import { RWA, Chain, type SDKInit } from "@peaq-network/rwa";
import { JsonRpcProvider } from "ethers";

async function main() {
  // 0. Create RWA instance and get provider
  const provider = new JsonRpcProvider(process.env.HTTPS_BASE_URL);
  const init: SDKInit = { chainId: Chain.AGUNG, provider: provider };
  const rwa_sdk = new RWA(init);

  // 1. Get a known Machine NFT and tokenId
  const machineNft = "0x5Ca3db1f292f913DDdA8C5385E5391438665463c";
  const tokenId = "tokenId";

  // 2. Read DID document
  const result = await rwa_sdk.mnft.getMachineDid({
    machineNft,
    tokenId
  });
  console.log("Result", result);
}

main().catch((err) => {
  console.error(err);
  process.exit(1);
