# UX enabling features

Firebird offers many features that allow developers to simplify the Web3 interaction processes and overcome a lot of user experience difficulties. Here are some top-notch features that the network is optimized for:

* **Signing Key** - Used in place of the private key, each signing key has an expiry time and a limited set of permissions. Hence, leaking has much less serious consequences. This more efficient signing process improves both application security and the UX safeguard of the keys.
* **Flexible Payer** - Applications can pay transaction fees for users in a decentralized manner. As a result, these apps can employ much more flexible monetization strategies, such as free, freemium, pay-to-unlock, and in-app-purchase models, so the onboarding becomes seamless.
* **Assets Inheritance** - The asset inheritance feature allows the user to set others as his inheritors. When the owner is inactive for a predefined period, one inheritor could activate the inheritance workflow to claim his inheritance rights.
