async function createAMM(): Promise<void> {
  const client = new Client('wss://honeycluster.dev');
  await client.connect();

  const wallet = Wallet.fromSeed('s...');
  const prepared = await client.autofill({
    TransactionType: 'AMMCreate',
    Account: wallet.address,
    Amount: { currency: 'USD', issuer: 'r...issuer', value: '100' },
    Amount2: '100000000',
    TradingFee: 500,
  });
  const signed = wallet.sign(prepared);
  const res = await client.submitAndWait(signed.tx_blob);
  console.log(res);
  await client.disconnect();
}

createAMM().catch(console.error);
