Usage

TypeScript

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

async function main() {
  // 0. Create RWA instance and 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. Machine Controller
  const controller = new Wallet(process.env.ALICE_PRIVATE_KEY!, provider);

  // 2. Approve the vault for specific MNFT token IDs
  const result = await rwa_sdk.vault.nftApproval({
    machineController: controller,
    nft: "0x5Ca3db1f292f913DDdA8C5385E5391438665463c",
    vault: "0x907229D0A25A5Bb16F0ff3D890f38Eb4Ad52Ea1a",
    tokenIds: [
      "1262843802665614120367007478296348432923457422026",
      "880598419457374294774049460835571533031091411284"
    ]
  });
  console.log("Result", result);
}

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

JavaScript

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

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

  // 1. Machine Controller
  const controller = new Wallet(process.env.ALICE_PRIVATE_KEY, provider);

  // 2. Approve the vault for specific MNFT token IDs
  const result = await rwa_sdk.vault.nftApproval({
    machineController: controller,
    nft: "0x5Ca3db1f292f913DDdA8C5385E5391438665463c",
    vault: "0x907229D0A25A5Bb16F0ff3D890f38Eb4Ad52Ea1a",
    tokenIds: [
      "1262843802665614120367007478296348432923457422026",
      "880598419457374294774049460835571533031091411284"
    ]
  });
  console.log("Result", result);
}

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

Example outputs

Result {
  status: 'approved',
  nft: '0x5Ca3db1f292f913DDdA8C5385E5391438665463c',
  vault: '0x907229D0A25A5Bb16F0ff3D890f38Eb4Ad52Ea1a',
  newlyApprovedTokenIds: [
    '1262843802665614120367007478296348432923457422026',
    '880598419457374294774049460835571533031091411284'
  ],
  receipts: [
    TransactionReceipt { ... },
    TransactionReceipt { ... }
  ]
}

This approves specific token IDs, not setApprovalForAll.
