### requiredSigner

```
requiredSigner: string;
```

Defined in: [atomiq-sdk/src/types/SwapExecutionAction.ts:213](https://github.com/atomiqlabs/atomiq-sdk/blob/786509324f7f09c427e9ccfe527d82e496f06af5/src/types/SwapExecutionAction.ts#L213)

The address of the signer that has to sign the transactions

***

### submitTransactions()

```
submitTransactions: (txs, abortSignal?, idempotent?) => Promise<string[]>;
```

Defined in: [atomiq-sdk/src/types/SwapExecutionAction.ts:209](https://github.com/atomiqlabs/atomiq-sdk/blob/786509324f7f09c427e9ccfe527d82e496f06af5/src/types/SwapExecutionAction.ts#L209)

Submits the signed transactions and waits for their confirmation

#### Parameters

| Parameter      | Type                                    |
| -------------- | --------------------------------------- |
| `txs`          | (`T`\[`"SignedTXType"`] \| `string`)\[] |
| `abortSignal?` | `AbortSignal`                           |
| `idempotent?`  | `boolean`                               |

#### Returns

`Promise`<`string`\[]>

#### Remarks

This might not do any validation on the submitted transactions, so returned txids are informational only and may not be persisted immediately. The swap may wait for an authoritative state transition before considering the submitted transactions accepted.

Make sure to only submit valid signed transactions obtained from this action object, and pass an AbortSignal if you need a timeout, otherwise this call can wait indefinitely when invalid transactions are submitted.
