Uniswap is one of the most widely used decentralized applications (dApps) in the cryptocurrency space, leading the decentralized finance (DeFi) ecosystem since its inception. With a monthly trading volume exceeding $2.88 trillion** and a **Total Value Locked (TVL)** of **$3.24 billion, Uniswap ranks among the top dApps globally. This guide explores how Uniswap works, its key features, and how to use it effectively.
What Is Uniswap?
Uniswap is a decentralized exchange (DEX) that allows users to trade cryptocurrencies without intermediaries. Unlike centralized exchanges (CEXs) like Binance or Coinbase, Uniswap operates without KYC requirements, enabling secure, fast, and permissionless trading.
How Uniswap Works
Uniswap uses an Automated Market Maker (AMM) model instead of traditional order books. Here’s how it functions:
- Liquidity Pools: Traders swap tokens using liquidity pools—smart contracts holding paired assets (e.g., ETH/USDT).
- Dynamic Pricing: Prices adjust automatically based on supply and demand within the pool. For example, selling ETH increases USDT supply, lowering ETH’s price.
- Decentralized Execution: Transactions occur directly on-chain via Ethereum or Layer 2 networks like Arbitrum.
