Good day,

I implemented a function to send a specified amount of funds from one wallet to another.  
I added the calculation of fees and gas. Everything worked well when I sent the entire wallet balance.

However, when I sent only 50%, I encountered a situation where the remaining funds in the sender’s wallet disappeared.

After that, I compared the transaction generated by my method with the one created by the Fuel wallet.  
I discovered that my transaction lacks the `CHANGE` block, which contains the remaining wallet balance.

I would like to ask for your assistance:

1. What is the mistake in my code?

```auto

export async function transferWithFeeAdjustment(
    wallet: WalletUnlocked,
    destination: AddressLike,
    assetId: BytesLike,
    amountToSend: BN
): Promise<void> {
    const txRequest = new ScriptTransactionRequest();

    const resources = await wallet.getResourcesToSpend([
        { amount: amountToSend, assetId },
    ]);
    txRequest.addResources(resources);

    txRequest.addCoinOutput(destination, amountToSend, assetId);

    const chainInfo = wallet.provider.getChain();
    const minGas = txRequest.calculateMinGas(chainInfo);
    const maxGas = txRequest.calculateMaxGas(chainInfo, minGas);

    txRequest.maxFee = maxGas.mul(1.1);

    const txCost = await wallet.getTransactionCost(txRequest);

    const transactionFee = txCost.maxGas
    txRequest.gasLimit = transactionFee;

    if (amountToSend.lte(transactionFee)) {
        throw new Error(
            "Insufficient balance to cover transaction fee. Please add more funds."
        );
    }

    const adjustedAmount = amountToSend.sub(transactionFee);
    if (adjustedAmount.lte(new BN(0))) {
        throw new Error(
            "Insufficient amount after deducting transaction fee. Unable to proceed."
        );
    }

    txRequest.outputs = [];
    txRequest.addCoinOutput(destination, adjustedAmount, assetId);

    const response = await wallet.sendTransaction(txRequest);

     await retry(async () => {
        return await response.wait();
    }, 10);

    return Promise.resolve()
}

```

1. I found documentation on sending funds using a Predicate. Would it be better for me to use this method instead?

Hey @Antik21 👋

The following line will be your issue, as within the `addResources` method, we also add the associated change to the output.

```ts
txRequest.outputs = [];

```

* * *

I’d suggest to use the [`transfer`](https://docs.fuel.network/docs/fuels-ts/wallets/wallet-transferring/#example) or `createTransfer` function:

```ts
const response = await wallet.transfer(
  destination,
  amountToSend,
  assetId
);

```

This will return any unused coins from the transfer back the sender 🙂

You are right!  
Thk you!

Now i use

```auto
const response = await wallet.transfer(
        destination,
        adjustedAmount,
        assetId
    );

```

Istead of

```auto
 txRequest.outputs = [];
 txRequest.addCoinOutput(destination, adjustedAmount, assetId);
  const response = await wallet.sendTransaction(txRequest);

```
