Swap vs. DEX: What's the Difference?

What Is Decentralized Exchange (DEX)?

A DEX, short for decentralized exchange, is a peer-to-peer marketplace that facilitates the transaction of cryptocurrencies using blockchain-run smart contracts. DEXs are characterized by the lack of mediation by central banks, governments, or other intermediaries. 

Decentralized crypto exchanges launch liquidity pools with an array of trading pairs. Since they are mostly noncustodial, you don’t have to hand over your assets to the exchange. Instead, you keep them in a DEX wallet of your choice. They offer greater flexibility and usability for trading native and non-native tokens. 

Some of the most popular DEX platforms are Uniswap, PancakeSwap, and SushiSwap. 

What Is a Swap?

As the name implies, swap is a service on DEXs where you exchange one crypto for another.

Let’s say you want to buy 500 BUSD and you have some BNB in your wallet. Rather than going to a centralized exchange and buying BUSD with your fiat money, you can directly buy BUSD with BNB using the swap function. All you need to do is head down to a DEX like PancakeSwap and enter the amount of BUSD you want. A small platform fee and a gas fee will be added to the payment. Once you confirm the transaction, the crypto assets are instantly transferred to your wallet. 





Now you know why most DEXs come with a 'Swap' in their name.

Differences Between Swap and DEX

Since a DEX is a platform and swap is a function, they are incomparable.
