FAQ

Do I pay network fees on payouts?

Yes. A payout is an outbound on-chain transaction, and every on-chain send carries a network fee for the chain it moves on. Because your side is the one sending the funds, that fee comes out of your side of the transfer. It is paid to the destination network — its validators or miners — not to halfin, which neither sets the fee nor collects it.
