# Introduction

## What is WeissFi?

WeissFi is a **decentralized lending protocol** built on the **Sui blockchain**, allowing users to **borrow against their digital assets** with **user-defined interest rates**. Designed for **capital efficiency** and **transparency**, WeissFi reimagines on-chain lending by giving users complete control over their borrowing terms.

* **Optimized Liquidations** – Stability Pools protect users from sudden liquidations while ensuring fair collateral management.
* **Seamless On-Chain Borrowing** – Leveraging **Sui's high-speed, low-cost transactions**, WeissFi makes decentralized lending more **efficient and accessible**.
