# sendTransaction (TON)

# sendTransaction

Sends a custom TON transaction with arbitrary message payloads. This is useful for smart contract calls, multi-message transactions, and contract deployment.

## Usage

```javascript theme={"system"}
import { sendTransaction, isTonWalletAccount } from "@dynamic-labs-sdk/ton";
import { getPrimaryWalletAccount } from "@dynamic-labs-sdk/client";

const walletAccount = getPrimaryWalletAccount();

if (walletAccount && isTonWalletAccount(walletAccount)) {
  const { transactionHash } = await sendTransaction({
    walletAccount,
    request: {
      validUntil: Math.floor(Date.now() / 1000) + 60, // 60 seconds from now
      messages: [
        {
          address: "UQDrjaLahLkMB-hMCmkzOyBuHJ186Qg_CZQhrOhIPBr0oDkB",
          amount: "100000000", // 0.1 TON in nanotons
        },
      ],
    },
  });

  console.log("Transaction hash:", transactionHash);
}
```
