# Protocol Overview Ferro Protocol features liquidity pools, with each pool featuring a pair of tokens. Liquidity providers can deposit tokens into the pool, whereas traders could swap between the tokens. The protocol follows a **Hybrid Invariant Model**. This unique price curvature results in two benefits: 1. Effective maintenance of peg 2. More efficient trades at higher volumes --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
