# Use Cases

Current use cases include:

* [lending-sdk](https://docs.protocolink.com/lending-sdk "mention"): supports mainstream lending protocols such as aave, compound, radiant, spark etc, and features such as leverage, deleverage, collateral swap, and zaps.
* [compound-kit](https://docs.protocolink.com/compound-kit "mention"): supports compound v3 and features such as leverage, deleverage, collateral swap, and zaps.

Potential use cases include:

* **Employing** [**flash loans**](https://docs.protocolink.com/use-cases/flash-loans) **to manage lending positions and execute liquidations**
* **Facilitating** [**zap-in and zap-out**](https://docs.protocolink.com/use-cases/zap-in-and-zap-out) **functionality for any token within your apps**
* **Developing a multi-send application for airdrops or asset transfers**
* **Build a DEX aggregator utilizing your own algorithm**
* **Creating an arbitrage bot**

Additionally, developers can add new protocols to the SDK (without smart contracts) if they are not already available.

## Creativity is Unlimited

By virtue of its composability, the blockchain provides you with the ability to accomplish tasks that are beyond the scope of the Web2 universe. You can use this feature to construct your own applications in a modular fashion, much like assembling Lego pieces. With our platform and your ingenuity, the potential for developing novel applications is endless.
