DEX

– short for decentralized exchange.  

A cryptocurrency exchange that utilizes Smart Contracts to connect directly with your decentralized wallet software - to enable trade settlements directly between buyer and sellers.  

In many cases, cryptocurrencies can be listed freely without having to pass through a centralized gatekeeper or pay listing fees.

Not every transaction needs a middleman..

Yeah, the miners get paid the gas fees you needed when you used that DEX..
