# What is BrownFi?

BrownFi invents a novel pricing mechanism for spot AMM based on oracles, to offer high capital efficiency, flexible market making, and simple UX. The core concept of BrowmFi AMM employs an elastic parameterization of a Limit Orderbook (LOB).

Instead of operating like a traditional AMM (like Uniswap) that derives prices from bonding curves or pool depth, BrownFi acts more like an RFQ/PopAMM with oracle-based prices at a competitive rate but requiring very little capital. This brings BrownFi some advantages over other AMMs:

* High capital efficiency with effortless position management
* No out-of-range risk
* Dynamic market making from simple to complex strategies by tuning a set of parameters.

BrownFi is built on the same mathematical codebase as Uniswap V2, but extends it with oracle integration, skewness-based incentives, and - in V3 - asymmetric liquidity depth and bid-ask spread. Every version has been externally audited: V1 by [Verichain](https://github.com/verichains/public-audit-reports/blob/main/Verichains%20Public%20Audit%20Report%20-%20BrownFi%20AMM%20Smartcontracts%20-%20v1.0.pdf), V2 by [Certik](https://skynet.certik.com/projects/brownfi), and V3 by Zenith and Sherlock.
