What Is a Decentralized Exchange?

Unlike traditional stock exchanges like the NYSE, decentralized exchanges (DEXs) operate without a central authority. Instead, they enable peer-to-peer trading directly between users via blockchain technology.

Key Features:

• No Intermediaries: Trades occur directly between users.
• Non-Custodial: Users retain full control of their funds.
• Transparency: All transactions are recorded on a public blockchain.

How Does a Decentralized Exchange Work?

DEXs rely on smart contracts to automate trades. Here’s a simplified breakdown:

1. Liquidity Pools: Users deposit tokens into shared pools to facilitate trading.
2. Smart Contracts: Execute trades when conditions are met (e.g., price matches).
3. Blockchain Settlement: Transactions are recorded on-chain for transparency.

Popular protocols like Uniswap and Balancer use this model.

Benefits of Using Decentralized Exchanges

1. Self-Custody: Users control their private keys.
2. Privacy: Minimal KYC requirements.
3. Censorship-Resistant: No central authority can halt trading.
4. Global Access: Available to anyone with an internet connection.

Drawbacks of Decentralized Exchanges

1. Complexity: Steeper learning curve for beginners.
2. Slower Speeds: Transaction times depend on blockchain congestion.
3. Limited Fiat Support: Most DEXs trade only cryptocurrencies.
4. Impermanent Loss: Risk for liquidity providers.

Types of Decentralized Exchanges

| Type | Description | Example |
|-----------------------|--------------------------------------|-----------------|
| AMM | Uses liquidity pools and algorithms | Uniswap |
| Orderbook DEX | Matches buy/sell orders | Binance DEX |
| Peer-to-Peer (P2P)| Direct trades between users | LocalBitcoins |
