Uniswap is a decentralized exchange using an automated liquidity protocol. Unlike traditional centralized exchanges, it does not use an order book, and allows traders to trade directly from their wallets without any intermediaries, making it censorship-resistant. Despite its significant ease-of-use improvements over time, many wonder how to use Uniswap with MetaMask.

Uniswap’s success is largely thanks to its innovation in the lending game; instead of the typical order book seen in centralized exchanges, the DEX implemented an automated market maker (AMM) with its own formula, called the “constant product market maker,” which redefines the way liquidity pools attract liquidity for its users.

In order to use Uniswap’s features, such as the liquidity pools, you need a crypto wallet like MetaMask. But what is a liquidity pool, you might ask?

Liquidity pools are, in essence, a smart contract, and a smart contract is a coded digital agreement that dictates certain functions and commands in a decentralized network or protocol. Therefore, in a liquidity pool, the liquidity providers deposit tokens which are used by traders, and trading fees are automatically distributed to pool participants.

What is MetaMask?

MetaMask is an Ethereum wallet available for iOS and Android devices and can be installed as a browser extension for Firefox, Google Chrome, Edge, and Opera. The app provides users access to over 2000 decentralized applications on multiple networks, including Ethereum, Avalanche, BNB Chain, and Arbitrum.
