LGTM

@0xmaayan , is there a better way to import this than using a relative path like this?

[0xmaayan]

You can import 'Type' and then use it 'Type.'

[junkil-park]

Applied. Thank you!

Great! A lot simpler :D

Would be nice to have alice and bob's balance tracked from before and after and then print out the gas fees so you can see that Alice's balance didn't change and Bob's did, in the same amount as the gas fees paid:

  const aliceBalanceBefore = await getBalance(alice);
  const bobBalanceBefore = await getBalance(bob);
  console.log(`Alice's balance: ${aliceBalanceBefore} octas`);
  console.log(`Bob's balance: ${bobBalanceBefore} octas`);
  
  // ... submit tx
  
  const response = await client.waitForTransactionWithResult(txnHash, { checkSuccess: true });
  const { gas_used, gas_unit_price } = response as any;
  
  // ... print token amt
  
  // Check that Alice did not pay the fee, but Bob did.
  const aliceBalanceAfter = await getBalance(alice);
  const bobBalanceAfter = await getBalance(bob);
  console.log(`Alice's balance: ${aliceBalanceAfter} octas`);
  console.log(`Bob's balance: ${bobBalanceAfter} octas`);

  console.log(
    "\n=== Check Bob and Alice's balance changes ===\n" +
      `Alice's balance change: ${aliceBalanceBefore - aliceBalanceAfter} octas\n` +
      `Bob's balance change: ${bobBalanceBefore - bobBalanceAfter} octas\n` +
      `The gas fees were: ${gas_used * gas_unit_price} octas`,
  );

  );

Thank you for the nice suggestion! I updated it to display the gas fee usage per transaction!
