# Overview

The Loopscale Protocol is a modular, order book–based lending protocol on Solana. The core Loopscale protocol is a powerful order book and matching engine. The design of the protocol is conceptually simple, creating an unbiased, extensible foundation for new financial products and markets.

The Loopscale Protocol additionally includes a series of risk and liquidity primitives to deliver the liquidity and simplicity expected by typical DeFi users. This modular, first-principles approach enables anyone to access the benefits of the Loopscale Protocol without sacrificing the scalability and flexibility of the core protocol.
