// import QUBIT Casper library
const { Casper } = require('@nest25/casper-lib');
// create a new Casper instance
const casper = new Casper();

// set testnet variables
const testPrivateKey = 'your-private-key';
const publicKey = '013a156a50fc6284ba436aedeaf96b55ac1a0c57ee9f8a46bf1c6518afe9b2f56c';
const RPC_API = 'https://rpc.testnet.casperlabs.io/rpc';

async function main() {
  // transfer NFT
  const result = await casper.transferNFT(
    RPC_API,
    testPrivateKey,
    872222,
    '017224493871278b24d2e9588b0ccc2f80e226aaff9b676ca00d031221bc73b61e',
