# sendRawTransaction

# sendRawTransaction

Sends a raw Bitcoin transaction using the mempool.space API. This is useful when you have a fully constructed and signed raw transaction that you want to broadcast to the network.

## Usage

```javascript theme={"system"}
import { sendRawTransaction, isBitcoinWalletAccount } from "@dynamic-labs-sdk/bitcoin";
import { getPrimaryWalletAccount } from "@dynamic-labs-sdk/client";

const walletAccount = getPrimaryWalletAccount();

if (walletAccount && isBitcoinWalletAccount(walletAccount)) {
  const { transactionId } = await sendRawTransaction({
    walletAccount,
    rawTransaction: "0100000001...", // Hex-encoded raw transaction
  });

  console.log("Transaction broadcast:", transactionId);
}
```

## Parameters

| Parameter        | Type                       | Description                                                             |
| ---------------- | -------------------------- | ----------------------------------------------------------------------- |
| `rawTransaction` | `string`                   | The raw transaction in hexadecimal format                               |
| `walletAccount`  | `BitcoinWalletAccount`     | The wallet account (used to determine network)                          |
| `client`         | `DynamicClient` (optional) | The Dynamic client instance. Only required when using multiple clients. |

## Returns

`Promise<{ transactionId: string }>` - A promise that resolves to an object containing the transaction ID.

## Errors

| Error                            | Description                               |

| `SendBitcoinRawTransactionError` | Thrown if the transaction broadcast fails |

## React

```tsx theme={"system"}
import { sendRawTransaction, isBitcoinWalletAccount } from '@dynamic-labs-sdk/bitcoin';
import { useGetWalletAccounts } from '@dynamic-labs-sdk/react-hooks';
import { useState } from 'react';

function BroadcastButton({ rawTransaction }) {
  const { data: walletAccounts = [] } = useGetWalletAccounts();
  const walletAccount = walletAccounts.find(isBitcoinWalletAccount);
  const [txId, setTxId] = useState('');

  const handleBroadcast = async () => {
    if (!walletAccount) return;
    const { transactionId } = await sendRawTransaction({ walletAccount, rawTransaction });
    setTxId(transactionId);
  };

  return (
    <div>
      <button onClick={handleBroadcast} disabled={!walletAccount}>Broadcast</button>
      {txId && <p>Transaction ID: {txId}</p>}
    </div>
  );
}
```
