import { Provider } from "@project-serum/anchor"
import { Keypair, Connection, clusterApiUrl } from 'solana/web3js`;
import { tokenSwapProgram } from 'rly-js';

const walletKeyPair = Keypair.generate();
const provider = new Provider(new Connection(clusterApiUrl("devnet")), new NodeWallet(walletKeyPair), {});

const tokenSwap = await tokenSwapProgram(provider);
