# Sign a Transaction

A web application may also request Adena to **create a signed transaction** via the `adena.SignTx` method. Upon receiving the request, Adena will prompt the user to sign the transaction.

If the user proceeds to sign the transaction, Adena will return the encoded transaction data on the console.

#### Code

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