What is Uniswap V3?

Uniswap V3 is a decentralized exchange (DEX) that operates on multiple blockchains, including Ethereum and other Ethereum-compatible networks. It allows users to trade various cryptocurrencies in a decentralized and trustless manner, eliminating the need for a centralized exchange.

Uniswap V3 utilizes an automated market maker (AMM) model, where the price of assets is determined by the ratio of tokens in a liquidity pool, rather than the traditional supply and demand dynamics of buyers and sellers. This ensures faster and more efficient trading, often with lower fees compared to centralized exchanges.

Uniswap V3 introduces exciting new features such as concentrated liquidity, where liquidity providers can specify price ranges for their contributions. This results in improved capital efficiency and potentially higher returns. Additionally, Uniswap V3 allows for the creation of custom fee structures and provides enhanced flexibility for liquidity providers.

Operating across multiple chains, Uniswap V3 expands its reach and usability, offering users the ability to trade on various blockchain networks. By creating and contributing to liquidity pools, users can earn trading fees in the form of UNI tokens, incentivizing liquidity provision and helping to create more liquid markets for trading.

What is Liquidity Mining?

Liquidity mining, also known as yield farming, is the act of providing liquidity via cryptocurrencies to decentralized exchanges (DEXs). Since the primary goal of an exchange is to be liquid, DEXs seek to reward users willing to bring capital to their platform.

Most DEXs are decentralized by replacing order books with an Automatic Market Maker (AMM). An AMM is a smart contract that regulates trading. Since smart contracts are decentralized, users do not have to trade the order book of an exchange. Instead, they effectively trade with other users.

The AMM collects these fees and grants them to each liquidity provider (LP) as a reward. Therefore, the DEX offers a symbiotic ecosystem where each group of users helps each other. While the token swapper pays a small fee to trade on a decentralized exchange, the liquidity provider earns money for providing the liquidity that the first user will need.
