What Is Uniswap? Understanding the DEX and UNI Token

Uniswap is a prominent decentralized exchange, or DEX, that swaps tokens through smart contracts without a company or broker matching trades. This guide explains its operation, UNI and the risks.

What is Uniswap?

Uniswap is a prominent decentralized exchange running on Ethereum. Unlike centralized exchanges such as Binance or Upbit, it uses smart contracts, automatically executing programs, to process swaps. Code replaces the intermediary that would otherwise find a counterparty.

Users can connect a self-managed wallet and swap tokens without signing up or completing identity verification. For context, see the comparison of centralized and decentralized exchanges.

AMMs: Pricing without an order book

Traditional exchanges match buy and sell orders in an order book. Uniswap instead uses an automated market maker, or AMM.

The core mechanism is a liquidity pool. Users deposit pairs of tokens, and a mathematical formula calculates prices from the pool's proportions. Buying a token reduces its quantity in the pool and raises its price; selling adds to its quantity and lowers its price.

Liquidity provision earns fees but carries impermanent loss risk. When the relative prices of deposited tokens change substantially, their value in the pool can fall below simply holding them. See DeFi for related concepts.

What does UNI do?

UNI is Uniswap's governance token. Holders can vote on the protocol's operating direction.

Holding UNI does not automatically generate fee income. Its value depends on protocol usage, market supply and demand, governance decisions and other factors. Measures such as market capitalization help assess its scale.

Main risks to understand

• Smart contract risk: Code defects or vulnerabilities can cause fund losses.
• Gas costs: During Ethereum congestion, gas fees can exceed the value of a small trade. Layer 2 networks can reduce costs.
• Scam tokens: Anyone can register tokens, including fakes. Learn how to avoid scams.
• Slippage: Low liquidity can create a large difference between expected and actual execution prices.
• Personal responsibility: Without an intermediary, wrong-address transfers and lost wallets cannot simply be reversed.

Recap

Uniswap swaps tokens through smart contracts without an intermediary, using AMMs and liquidity pools to calculate prices. UNI supports governance. Its openness and convenience come with personal responsibility for smart contract risks, fraudulent tokens and gas costs.
