Intro to Decentralized Exchanges (DEX)
Decentralized Exchanges (DEXs) are blockchain-based platforms that allow users to trade cryptocurrencies directly with one another without relying on a central authority. These platforms utilize smart contracts to automate trades and custody, empowering users to maintain full control of their assets.
How DEX Works
Unlike centralized exchanges, DEXs operate on peer-to-peer (P2P) networks. Orders are executed through smart contracts directly on the blockchain. Users connect wallets like MetaMask or Trust Wallet and trade using liquidity pools instead of traditional order books.
Security and Control
DEX users retain custody of their funds at all times. Since no central entity holds your assets, the risk of exchange hacks or frozen accounts is eliminated. However, users must take responsibility for wallet security and understanding how to interact with smart contracts safely.
Benefits of Using a DEX
- No KYC or registration required
- Full custody of your assets
- Access to early-stage and niche tokens
- Transparent on-chain transactions
Challenges to Consider
- No customer support or recovery if keys are lost
- Complex UI for beginners
- Higher gas fees depending on blockchain used
