# Exchange PolyDEX is an Automated Market Maker (AMM), and the Exchange is at the heart of PolyDEX. The PolyDEX Exchange offers several features that support decentralized trading: ### Swapping/Trading PolyDEX lets users trade without the need to go through a Centralized Exchange. Everything you do on PolyDEX is routed directly through your own wallet—no need to trust someone else with your coins! ### Liquidity Pools You can only swap tokens on PolyDEX if there is enough liquidity for those tokens. If nobody has added much liquidity for the token or tokens you want to swap, it will be difficult, expensive, or impossible to do so. Providing liquidity will get you PolyDEX-LP Tokens, which will earn you rewards in the form of trading fees for making sure there's always liquidity for the exchange to use. ### Yield Farming Yield farming lets users that are providing liquidity earn CNT and other tokens as rewards by locking their LP tokens into a Farm smart contract. The incentive is to balance out the risk of [impermanent loss](https://academy.binance.com/en/articles/impermanent-loss-explained) that comes along with locking in your liquidity. ### Initial Farm Offerings (IFOs) An Initial Farm Offering is an event that lets users access farms / pools for partner projects of PolyDEX in a separate dedicated page. This page also has the information about the project and their token. In most cases, farms / pools under IFO will give out multiple tokens as reward for staking in one type of token. This increases the chances of overall returns ( APR ) massively. --- # 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.
