What are “Maximum return” and “lowest gas cost” in the Basic settings?

If you choose the “Maximum return” option, the algorithm will use complex routes for the swap to make sure that you get the best rates.

Alternatively, you can go for the “Lowest gas cost” option. In that case, the spaceflight algorithm will find the best option in terms of gas costs. This option comes in handy for small trades when you don’t want to pay substantial fees, like, for instance, swapping 0.006 ETH to USDT. Small trades optimize fewer liquidity sources and thus the lowest gas cost option will most likely deliver the best end price.
