Frequently Asked Questions (FAQ)
Q: What is a decentralized exchange (DEX)?
A: A DEX is a peer-to-peer marketplace where transactions occur directly between crypto wallets using smart contracts. Unlike centralized exchanges, there's no middleman holding user funds.
Q: Are DEXs safe to use?
A: DEXs are generally safer in terms of asset custody since users keep control of their keys. However, risks include smart contract vulnerabilities and phishing attacks. Always verify contract addresses and use trusted wallets.
Q: How do I start trading on a DEX?
A: You’ll need a Web3 wallet (like MetaMask), some cryptocurrency for gas fees, and a connection to the DEX platform. Then simply connect your wallet and begin swapping or providing liquidity.
Q: Can I trade fiat currencies on a DEX?
A: Most DEXs don’t support direct fiat deposits. You typically need to purchase crypto on a centralized exchange first and transfer it to your wallet.
Q: What are gas fees on DEXs?
A: Gas fees are network charges paid to miners or validators for processing transactions. Fees vary by blockchain—Ethereum tends to be more expensive than BNB Chain or Polygon.
Q: Why use a DEX instead of a CEX?
A: DEXs offer greater privacy, resistance to censorship, and full control over funds. They’re ideal for users who prioritize decentralization and long-term asset management.
