### permitAndCall

Executes a permit and then performs an action in a single transaction.

```

#### Parameters

* `action` (bytes): The action to execute after the permit

// Execute permit and action in one transaction
await papayaContract.permitAndCall(permitData, actionData, {
  value: ethers.utils.parseEther("0.1")
});
```
