# TransactionAccepted

Fires when a transaction is accepted into the node's mempool (before execution).

## Import

```ts
import { SseClient, EventName } from 'casper-js-sdk';
```

## Usage

```ts
sseClient.subscribe(EventName.TransactionAcceptedEventType, (raw) => {
  const result = raw.parseAsTransactionAcceptedEvent();
  if (result.err) return;

  const tx = result.val.transactionAccepted;

  const v1Hash = tx.getTransactionV1()?.hash.toHex();
  console.log('Accepted transaction hash:', v1Hash);
});
```

## Payload

The payload wraps either a `TransactionV1` or a legacy `Deploy`.

```ts
interface TransactionAcceptedPayload {
  getTransactionV1(): TransactionV1 | undefined;
  getDeploy(): Deploy | undefined;
}
```

## Notes

- This event fires before execution. A `TransactionAccepted` does **not** mean the transaction succeeded.
- Listen for [`TransactionProcessed`](/sse/transaction-processed) for the execution outcome.
