Fees and the token
Every fill pays a fill fee in the token it receives. Every fee and every forfeited seal deposit accrues to the fee PDA, which no key signs for.
1 The fill fee
The fill fee is taken in the received token when the fill settles. Its rate is set in the program's Config.
2 Seal deposits
A small seal deposit in SOL rides with every commit. It comes back when the order settles or is cancelled, and goes to the fee PDA when an order is forfeited.
3 $UNISON
$UNISON: fair launch with a developer allocation. Supply fixed at 1,000,000,000.
The protocol's whole fee share accrues to the fee PDA: every fill fee and every forfeited seal deposit.
A crank buys $UNISON with the fee PDA's balances through Jupiter and burns it.
