# Documentation Overview
Curve is a **decentralized exchange (DEX) and automated market maker (AMM) on Ethereum and EVM-compatible sidechains/L2s**, designed for the **efficient trading of stablecoins and volatile assets**.

Additionally, Curve has launched its own stablecoin, **crvUSD**, and **Curve Lending**, both featuring a **unique liquidation mechanism** known as **LLAMMA**.

This documentation outlines the technical implementation of the core Curve protocol and related smart contracts. It may be useful for contributors to the Curve codebase, third-party integrators, or technically proficient users of the protocol.
