Uniswap is a decentralized exchange (DEX) protocol built on the Ethereum blockchain, enabling peer-to-peer trading of ERC-20 tokens without intermediaries. It operates via automated liquidity pools powered by smart contracts, eliminating the need for traditional order books.
Key Features of Uniswap
- Decentralized Exchange (DEX): Trade ERC-20 tokens directly from your Ethereum wallet without KYC or platform fees.
- Automated Market Maker (AMM): Uses liquidity pools and algorithms (Constant Product Formula) to determine token prices.
- UNI Governance Token: Holders vote on protocol upgrades and fund allocation.
- User-Friendly Interface: Intuitive web and mobile app integration with MetaMask, Trust Wallet, and other Ethereum wallets.
- Token Swaps: Seamlessly exchange Ethereum and ERC-20 tokens.
- Flash Swaps: Borrow tokens without collateral for arbitrage opportunities.
- Liquidity Mining: Earn UNI rewards by providing liquidity to pools.
- Self-Custodial: Retain full control of your assets; no third-party custody.
- Early Access to Tokens: Trade newly launched ERC-20 tokens before centralized exchanges list them.
Uniswap V3 Upgrades:
- Concentrated liquidity (up to 4,000x capital efficiency).
- Customizable fee tiers (0.01%–1%).
- Improved price oracles and lower gas fees.
- Range Orders: Liquidity providers (LPs) set narrow price ranges for targeted returns.
- Decentralized Governance: Community-driven decisions via UNI token voting.
- Security: Open-source, audited smart contracts reduce counterparty risk.
How Uniswap Works
Uniswap replaces order books with liquidity pools—smart contracts holding paired tokens (e.g., ETH/DAI). Traders swap tokens against these pools, and LPs earn fees (0.01%–1%) based on their share of liquidity.
Key Components:
- Smart Contracts: Execute trades autonomously.
- Liquidity Providers (LPs): Deposit tokens to enable trading and earn fees.
- UNI Token: Governs protocol changes and incentivizes participation.
