# Waiting for Confirmation

> Configure polling timeouts and handle transactions that take too long to land in a block

When you call `signAndBroadcast`, the client handles confirmation automatically:

1. The signed transaction is submitted via `broadcastTxSync` (CheckTx)
2. The client polls `getTx(txHash)` every 3 seconds (configurable)
3. Once the transaction appears in a block, the `DeliverTxResponse` is returned

## Configuring Timeouts

Control how long the client waits and how often it polls:

```typescript theme={"system"}
const client = await SigningStargateClient.connectWithSigner(
  "https://rpc.my-chain.network",
  wallet,
  {
    gasPrice: GasPrice.fromString("0.025uatom"),
    broadcastTimeoutMs: 120_000,
    broadcastPollIntervalMs: 5_000,
  },
);
```

| Option                    | Default        | Description                              |
| ------------------------- | -------------- | ---------------------------------------- |
| `broadcastTimeoutMs`      | `60_000` (60s) | Maximum time to wait for block inclusion |
| `broadcastPollIntervalMs` | `3_000` (3s)   | Interval between `getTx` polls           |

## Handling Timeouts

If the transaction is not included within the timeout, a `TimeoutError` is thrown. The transaction may still succeed — it could be sitting in the mempool:

```typescript theme={"system"}
import { TimeoutError } from "@cosmjs/stargate";

try {
  const result = await client.signAndBroadcast(senderAddress, [sendMsg], "auto");
} catch (error) {
  if (error instanceof TimeoutError) {
    const txHash = error.txId;
    const laterResult = await client.getTx(txHash);
  }
  throw error;
}
```

<Warning>
  A `TimeoutError` does **not** mean the transaction failed. The signed bytes were already submitted to the mempool. Always check with `getTx` before resubmitting, or you risk sending the transaction twice.
</Warning>
