It"s just what that guy had set, defaults from Boltz config. The more people will onboard, the more they will start competing with each other. The percentage fees will come down, like in any market. I hope the users of apps like Aqua will notice eventually and push for adoption too.

Interesting, thanks. So looks like right now the fees are identical (I'm just switching between boltz mainnet and eldamar mainnet), it's just the max swapsize that's different?
