Uniswap: A Decentralized Cryptocurrency Exchange
Uniswap is a decentralized cryptocurrency exchange (DEX) that enables peer-to-peer trading of digital assets without intermediaries. Unlike traditional exchanges, Uniswap operates via smart contracts rather than a centralized authority.
How Uniswap Works
Uniswap employs an Automated Market Maker (AMM) model, powered by liquidity pools—smart contracts funded with pairs of assets. When users execute trades, the AMM adjusts prices algorithmically based on the pool's asset ratios.
- Decentralized Trading: No intermediaries; users retain full control over funds.
- Eliminates Order Books: Uses liquidity pools for instant swaps.
- Reduced Slippage: Deep liquidity minimizes price impact.
Key Features
- Decentralization: Fully non-custodial; no central entity governs transactions.
- Seamless Swaps: Trade assets directly from a wallet (e.g., MetaMask).
- High Liquidity: Pools ensure 24/7 liquidity for listed tokens.
- Low Fees: Typical fees range from 0.01% to 0.3% per trade.
Use Cases
- Token Swaps: Exchange ETH for ERC-20 tokens like UNI or USDT.
- DeFi Integration: Access yield farming, staking, and other protocols.
- Liquidity Provision: Earn fees by depositing tokens into pools.
- Token Launches: New projects bootstrap liquidity via Uniswap.
Is Uniswap a Primary Market?
No. Uniswap functions as a secondary market for trading existing cryptocurrencies, not issuing new ones.
