Uniswap stands as one of the most widely used decentralized applications (dApps) in the cryptocurrency space, consistently leading the industry for years. This innovative trading platform has been instrumental in the expansion and maturation of the decentralized finance (DeFi) ecosystem.
Recent data highlights Uniswap's dominance, with a monthly trading volume exceeding $2.88 trillion and a total value locked (TVL) of $3.24 billion—a figure that has previously surged to $10 billion. These metrics firmly position it among the largest dApps globally. As Uniswap continues to make headlines, this guide delves into its inner workings, core components, and practical usage.
What Is Uniswap?
Uniswap is a decentralized exchange (DEX) that enables users to trade cryptocurrency assets without relying on traditional exchanges. Unlike centralized platforms, it eliminates the need for personal information disclosure or KYC (Know Your Customer) verification. Users can swap one cryptocurrency for another swiftly, securely, and in a fully decentralized manner. On Uniswap, this process is commonly referred to as "swapping," as one asset is directly exchanged for another.
How Uniswap Works
Centralized exchanges like Binance or Coinbase utilize order books to match buyers and sellers. Uniswap, however, employs an innovative mechanism known as the Automated Market Maker (AMM) model. This approach relies on liquidity pools—smart contracts that hold reserves of two or more assets.
When a trader executes a swap (e.g., converting 1 ETH to USDT), the AMM algorithm facilitates the trade using the ETH-USDT liquidity pool at the prevailing market rate. Each trade adjusts the pool's asset ratios, dynamically updating prices. For instance, selling ETH increases the pool's USDT supply, thereby lowering ETH's price, while buying ETH reduces USDT supply, driving ETH's price higher.
Launch and Historical Overview
Uniswap was launched in 2018 by Hayden Adams, who currently serves as CEO of Uniswap Labs, the development team behind the protocol. Its popularity surged rapidly due to its permissionless nature—no KYC or mandatory sign-ups were required. This user-friendly approach made it a preferred choice for traders seeking alternatives to platforms like Coinbase or Binance.

Core Developments in the Uniswap Ecosystem
UNI Token
The UNI token is an ERC-20 utility and governance token native to the Uniswap protocol. Initially distributed to liquidity providers, it is now tradable on multiple markets. UNI holders participate in governance decisions, influencing protocol upgrades and new feature implementations.
Unichain
Unichain is Uniswap's native Layer 2 blockchain, designed to optimize the DEX's functionality. Its mainnet launched in February 2025 after a year of development. Key features include 1-second block times and a 95% reduction in gas fees, making decentralized trading more accessible and cost-effective.
Uniswap V4
Uniswap V4 represents a significant upgrade from V3, introducing features like "Hooks"—customizable smart contract functions that enable advanced trading strategies, dynamic fees, and on-chain limit orders. The Singleton Contract architecture consolidates all liquidity pools into a single contract, reducing gas fees for pool creation by 92% and streamlining multi-hop swaps.
Uniswap V3 vs. V4: Key Differences
| Feature | Uniswap V3 | Uniswap V4 |
|---|---|---|
| Liquidity Management | Concentrated liquidity with price ranges | Optimized concentrated liquidity with Singleton model |
| Core Infrastructure | Separate smart contracts per pool | Single smart contract for all pools |
| Customization | Limited built-in options | "Hooks" for full pool customization |
| Transaction Efficiency | Higher gas consumption per transaction | Flash Accounting reduces gas costs |
| Layer 2 Support | Basic support | Full optimization for L2 networks |
How to Use Uniswap: Swapping and Providing Liquidity
Uniswap supports various activities beyond token swaps, including yield farming, liquidity pool creation, and initial token market launches.
How to Swap Tokens on Uniswap (ETH to USDT)
To swap tokens, users need a compatible crypto wallet (e.g., MetaMask) and funds on the relevant blockchain. Follow these steps:
