Protocol Revenue
The part of user fees a protocol keeps for itself, rather than passing on to liquidity providers, validators, or other suppliers.
Mechanically it is the output of a fee split: a parameter in the contracts routes a share of every fee to a treasury or a staking contract, and the rest goes to whoever supplied the service. The word revenue is borrowed from company accounting and the differences are important. Nothing is audited; there is no accrual accounting, so the figure is cash-like and lumpy; costs are generally not netted out, in particular token incentives paid to attract the very activity generating the fees; and income denominated in the protocol's own token can be circular. It is also price-dependent, since fees collected in volatile assets are converted at a rate that moves.
На практике
A lending protocol that takes a reserve factor on interest payments records that share as protocol revenue while the rest accrues to depositors.
Распространённое заблуждение

Показатель, которому это соответствует
