Uniswap V2 is a popular decentralized exchange (DEX) built on the Ethereum blockchain that allows users to swap various ERC-20 tokens directly from their wallets. It operates on an automated market maker model, meaning prices are determined by liquidity pools rather than traditional order books. This guide will walk you through the core use cases of Uniswap V2, including swapping tokens, providing liquidity, and removing liquidity. To begin using Uniswap V2, you need to have a compatible cryptocurrency wallet, such as MetaMask, and some Ethereum (ETH) to cover transaction fees. First, connect your wallet to Uniswap V2. Visit the Uniswap V2 interface at uniswap.org. Click on "Launch App" to access the trading interface. In the top right corner, you will see the option to connect your wallet. Select your wallet provider and follow the prompts to connect. Next, to swap tokens, choose the tokens you want to exchange. In the interface, there are two dropdown menus. Select the token you wish to sell in the first dropdown and the token you wish to buy in the second. Enter the amount you want to swap. The interface will display the estimated amount of the token you will receive and any slippage warnings. Review the information carefully, and if you are satisfied, click the "Swap" button. Confirm the transaction in your wallet, and wait for the transaction to be processed on the Ethereum blockchain. To provide liquidity, navigate to the "Pool" section of the Uniswap interface. Click on "Add Liquidity." You will need to select a token pair that you want to provide liquidity for. Enter the amount of each token you wish to deposit. Uniswap will automatically calculate the required amounts based on the current pool ratios. Review the information and click on "Supply." Confirm the transaction in your wallet, and once it is successful, you will receive liquidity tokens representing your share in the pool. If you want to remove liquidity, go back to the "Pool" section and find your liquidity position. Click on "Remove Liquidity."
