Unlike centralized exchanges, DEXs operate on a decentralized network, allowing users to trade cryptocurrencies directly with each other without the need for an intermediary. This eliminates the need for trust in a third party and reduces the risk of censorship or hacking.

Key Features of DEXs

1. Decentralized: No single entity controls the exchange.
2. Trustless: Users do not need to trust a third party to hold their funds.
3. Non-custodial: Users retain full control of their private keys.
4. Privacy: Transactions are typically anonymous or pseudonymous.
5. Transparency: All transactions are recorded on the blockchain and are publicly verifiable.

Benefits of Using DEXs

1. Increased security: Eliminates risk of hacks or breaches at centralized exchanges.
2. Control over funds: Users have full custody of their assets.
3. Lower fees: Typically lower trading fees compared to centralized exchanges.
4. Access to niche markets: Offer trading pairs not available on centralized exchanges.
5. Enhanced privacy: No KYC or personal information required.

Types of DEXs1. Automated Market Makers (AMMs)

• Facilitate trading by using liquidity pools filled by users who earn fees.
• Popular examples: Uniswap, PancakeSwap

2. Order Book DEXs

3. Hybrid DEXs

• Combine features of both AMMs and order book DEXs.
• Popular examples: Bancor, Loopring

Considerations When Using DEXs

• Lower liquidity compared to centralized exchanges.
• Higher transaction fees during periods of high network congestion.
• Limited user interface and support compared to centralized exchanges.
• Potential vulnerabilities in smart contracts underlying DEXs.
