# mina\_sendTransaction

{% hint style="info" %}
You need to create zk commond in zkApp first, then call Auro Wallet to sign and broadcast.
{% endhint %}

### Params

```typescript
interface SendTransactionArgs  {
    // only sign with auro wallet, auro-extension-wallet support from V2.2.16. 
    readonly onlySign?: boolean; 
    // custom nonce with auro wallet, auro-extension-wallet support from V2.3.0. 
    readonly nonce?: number; 
    // transaction is zk commond that create by contract.
    readonly transaction: string | object;
    // option. 
    readonly feePayer?: {
        // option. Auro Wallet also provide advance option to change fee.
        readonly fee?: number;
        // option.
        readonly memo?: string;
    };
}
```

### Result

```typescript
type SendTransactionHash = {
    // broadcast hash, you can query tx info by this hash.
    hash: string;
};

type SignedZkappCommand = {
    // results of JSON.stringify( signZkappCommand().data )
    signedData: string; 
};

type SendZkTransactionResult = SendTransactionResult | SignedZkappCommand

interface ProviderError extends Error {
    message: string; // error message.
    code: number; // error code.
    data?: unknown; // error body. 
}

Promise<SendTransactionResult | ProviderError>
```
