I'd just correct something, wizardswap is not an aggregator. It's a swap service with it's own liquidity, like the the first generation of swap services were.

It's interesting though in that you can provide liquidity to them and make some money off the fees, but best in mind it is a centralized service and if they were to ever take off with your coins there's not much you can do about it. Probably never gonna happen though, they've been pretty straight so far.
