Frequently Asked Questions (FAQ)

The main difference is custody of funds. On a CEX, the exchange holds your funds, while on a DEX, you retain control of your private keys and your funds are stored in your own wallet.

Which type of exchange is more secure?

DEXs are generally considered more secure because you control your own private keys, reducing the risk of hacking. However, you are also responsible for the security of your own wallet.

Which type of exchange is easier to use for beginners?

CEXs are generally easier to use for beginners due to their user-friendly interfaces and availability of customer support.

What are gas fees?

Gas fees are transaction fees paid to the blockchain network for processing transactions on DEXs. These fees can vary depending on network congestion.

What is KYC/AML?

KYC (Know Your Customer) and AML (Anti-Money Laundering) are regulatory requirements that require exchanges to verify the identity of their users to prevent illegal activities. CEXs typically have stricter KYC/AML requirements than DEXs.
