How DEX Trading Works and How to Compare Platforms
Summary
The guide explains decentralized exchanges as wallet-connected venues where smart contracts settle trades without centralized custody. It outlines two common designs: automated market makers, where users trade against token pools funded by liquidity providers, and orderbook exchanges, which match buy and sell orders on-chain. It also describes aggregators as tools that route swaps across sources of liquidity, potentially affecting execution price and slippage.
For comparing venues, it recommends considering liquidity, trading and network fees, supported assets and chains, wallet compatibility, interface features, and security information such as audits. It notes key risks including smart-contract vulnerabilities, scam tokens, phishing, and the absence of centralized listing standards. The platform rankings and fee or volume figures are presented without a date, sourcing, or consistent comparison method, while some sections promote a particular provider. Treat these figures as snapshots rather than a dependable ranking; actual costs and execution quality depend on the asset, chain, liquidity, and trade size.
Key ideas
- AMM-based DEXs execute trades against token pools, while orderbook DEXs match buy and sell orders.
- Liquidity providers supply assets to AMM pools and may receive a share of trading fees.
- DEX aggregators route trades across liquidity sources and can affect slippage and execution costs.
- Platform selection should account for liquidity, fees, supported networks, wallet fit, and security practices.
- Self-custody reduces reliance on exchange custody but leaves users exposed to contract, token, and phishing risks.
