# What is YO? YO stands for Yield Optimizer. YO is a DeFi protocol that helps you easily boost your crypto earnings without the hassle. YO automatically moves funds across the best-performing pools no matter the blockchain, so you’re always getting the **highest risk-adjusted yield**. YO leverages [Exponential.fi's Risk Ratings](https://exponential.fi/learn/risk-rating) to smartly balance risks and reward—so you don’t have to spend time managing risk yourself. YO is fully decentralized, meaning you’re always in control of your assets from your own wallet. If you want a simple, secure way to earn more from your crypto, YO’s got you covered. --- # 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.
