# Introduction

### About YiFi Swap <a href="#r12" id="r12"></a>

**YiFi Swap is an non-custodial multi-rail swap aggregator.**

Each request is routed across on-chain DEXs, off-chain CEX exchange partners, and dedicated private routes. Depending on the rail selected, you can prioritize by best pricing, execution time, or on-chain privacy.

### Why use YiFi Swap&#x20;

* **Multi-chain liquidity**: Tap into deep liquidity across EVM, Solana, Tron, Bitcoin and 150+ chains. See Supported chains.
* **Non-custodial throughout.** Funds stay in the user's wallet on DEX routes, or pass one-to-one through an exchange partner on CEX and private routes. YiFi never holds them.
* **Monetization built in.** Earn a revenue share on every attributed swap, with a configurable fee and attribution by API key or referral ID. See Fees and Partner Portal.
* **Distribution beyond the web**. The same rails run in web, mobile, and Telegram surfaces, not only in the browser.
