Binance is the first i think i dont need to do any comment on that .
IDEX and Switcheo.
These two exchanges are decentralised. Yes i know they are not fully dex. Beucase idex started to ban some ip's from USA and also they will want kyc from people also swh
is not a fully dex because they are not adding every nep5 tokens also they ddint add nex yet. But i love these dex's also.
