# Sign & Send a Transaction

A web application may create an unsigned transaction and request Adena to **sign and send the transaction** with the connected account via the `doContract` method. Upon receiving the request, Adena will prompt the user to approve the transaction. 

If the user approves the transaction, Adena will use the user's private key to sign the transaction to create a signed transaction and broadcast it immediately.

#### Code

```javascript
adena.DoContract({
    tx: {
        messages: [
            {
                type: "string",
                value: object
            },
            // you may add additional messages within the brackets
            ...
        ],
        memo?: string
    }, 
    isNotification?: boolean // default: true
)
```
