Hey there, there are some DEX that is available in the market like Uniswap, sushiswap , Honeyswapand etc. Not a finantial advice but I am presently farming XGT/xDAI at Honeyswap DEX. I think honeyswap is one of the best in space not only because of their low gas fees but also being a cross- chain capability. You can check them here: https://Xion.finance
