GroFi Dex serves as the core Automated Market Maker (AMM) on U2U Chain, positioning itself as the leading decentralized exchange (DEX) on U2U Chain.

GroFi Dex offers various features to facilitate decentralized trading:

## Buy/Sell

[GroFi Dex ](https://testnet.grofidex.io/swap)enables users to trade directly, bypassing the need for a Centralized Exchange. Transactions on GroFi Dex are routed through users' own wallets, eliminating the necessity to rely on third parties with their coins.

## Liquidity Pools <a href="#liquidity-pools" id="liquidity-pools"></a>

You can only swap tokens on [GroFi Dex](https://testnet.grofidex.io/pair) upon the availability of enough liquidity. If there's insufficient liquidity for the desired tokens, swapping may become challenging, costly, or even unfeasible.&#x20;

By providing liquidity, users receive LP Tokens, entitling them to rewards in the form of trading fees, thereby ensuring consistent liquidity provision for the exchange.

## Yield Farming

Yield farming on [GroFi Dex](https://testnet.grofidex.io/farms) allows liquidity providers to earn U2U rewards by locking their LP tokens into a smart contract. This incentivizes users to manage the risk of [impermanent loss](https://academy.binance.com/en/articles/impermanent-loss-explained) associated with locking liquidity.
