This guide shows how to send a single transfer from your Highload Wallet v3.

## Objective [#objective]

By the end of this guide, you will:

* Send a single TON transfer from your Highload Wallet v3
* Understand how `query_id`, `created_at`, and [send modes](/llms/foundations/messages/modes/content.md) work

## Prerequisites [#prerequisites]

* Completed [wallet creation](/llms/standard/wallets/highload/v3/create/content.md) with funded balance and saved configuration in `.wallet.json`

## Step 1: Load wallet configuration [#step-1-load-wallet-configuration]

Load the wallet data and create the wallet instance:

```typescript
import { TonClient, internal, toNano } from '@ton/ton';
import { mnemonicToPrivateKey } from '@ton/crypto';
import { Cell, SendMode } from '@ton/core';
import { HighloadWalletV3 } from './wrappers/HighloadWalletV3';
import { HighloadQueryId } from './wrappers/HighloadQueryId';
import * as fs from 'fs';

// Load wallet data
const walletData = JSON.parse(fs.readFileSync('.wallet.json', 'utf-8'));
const mnemonic = walletData.mnemonic.split(' ');
const keyPair = await mnemonicToPrivateKey(mnemonic);

const CODE = Cell.fromBoc(Buffer.from('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', 'hex'))[0];

const client = new TonClient({
    endpoint: 'https://testnet.toncenter.com/api/v2/jsonRPC', // This is TESTNET endpoint
    // apiKey: 'your-api-key' // Optional: get from @tonapibot or @tontestnetapibot
});

const wallet = client.open(
    HighloadWalletV3.createFromConfig(
        {
            publicKey: keyPair.publicKey,
            subwalletId: walletData.subwalletId,
            timeout: walletData.timeout,
        },
        CODE
    )
);
```

## Step 2: Prepare the transfer message [#step-2-prepare-the-transfer-message]

Create an internal message with the transfer details:

```typescript
const internalMessage = internal({
    to: 'EQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAM9c', // Zero address (for testing)
    value: toNano('0.01'),
    bounce: false,
});
```

This example uses the zero address for testing. Replace it with your actual destination address.

<Callout type="caution">
  **No state-init support:** Highload Wallet v3 cannot send messages containing [`StateInit`](/llms/foundations/messages/deploy/content.md) using this method.

  If you need to deploy a contract (send a message with `StateInit`), use [batch transfers](/llms/standard/wallets/highload/v3/send-batch-transfers/content.md) with an action list instead. See [Limitations and constraints](/llms/standard/wallets/highload/v3/specification/content.md) in the specification for details.
</Callout>

## Step 3: Send the transfer [#step-3-send-the-transfer]

Send the transfer using the `sendExternalMessage` method:

```typescript
const createdAt = Math.floor(Date.now() / 1000) - 30; // 30 seconds ago
const queryId = new HighloadQueryId(); // Represents query_id as a seqno

await wallet.sendExternalMessage(keyPair.secretKey, {
    message: internalMessage,
    mode: SendMode.PAY_GAS_SEPARATELY,
    query_id: queryId,
    createdAt: createdAt,
    subwalletId: walletData.subwalletId,
    timeout: walletData.timeout,
});

console.log('Transfer sent');
```

<Callout type="note">
  **Automatic deployment:** If your wallet is in `uninit` status (has a balance but no code), it will automatically deploy when processing this external message. The wallet transitions to `active` status, and the transfer is executed in the same transaction.
</Callout>

### Parameter explanation [#parameter-explanation]

**`query_id`** — Unique identifier for replay protection:

* Each `query_id` can only be processed once within the protection window
* `HighloadQueryId` is a wrapper class that represents the composite `query_id` as a sequential counter
* Provides `getNext()` method to increment to the next unique ID
* Total range: 8,380,416 unique IDs
* See [Query ID structure](/llms/standard/wallets/highload/v3/specification/content.md) for details

**`createdAt`** — Message timestamp for expiration:

* Set to 30 seconds **before** current time: `Math.floor(Date.now() / 1000) - 30`
* Compensates for blockchain time lag (lite-servers use last block time, not current time)
* See [Timestamp validation](/llms/standard/wallets/highload/v3/specification/content.md) for why this is necessary

## Next steps [#next-steps]

Your wallet is fully operational. You can send multiple transfers in parallel or batch multiple messages in one transaction.

To verify that your message, see [How to verify message is processed](/llms/standard/wallets/highload/v3/verify-is-processed/content.md).
