# BaseBeefyCurveStrategy

## Overview

The BaseBeefyCurveStrategy contract extends BaseBeefyStrategy to provide functionality for strategies that interact with both Beefy Finance and Curve protocols. It supplies underlying tokens into a Curve pool, then deposits the Curve LP tokens into a Beefy vault for additional yield.
