Protocol revenue
Protocol revenue is the part of the fees paid by users that a protocol keeps for its treasury or token holders after paying liquidity providers or suppliers.
Most DeFi protocols charge users fees, but much of that money goes straight to the people who supply capital: liquidity providers on a DEX, lenders in a money market or stakers in a liquid staking pool. Protocol revenue is the slice left over for the protocol itself, its DAO treasury or its token holders. Analytics sites show both lines, total fees and revenue, side by side.
The distinction matters for valuation. A DEX may generate huge fees while keeping none of them, which tells you its token captures little cash flow. Ratios such as price-to-fees or price-to-revenue compare market capitalisation or fully diluted value with annualised revenue, borrowing the logic of price-to-sales in equities.
Definitions vary between data providers, and revenue can be inflated by incentives paid back to users, wash trading or one-off events. It also says nothing about costs such as emissions, grants or salaries, so high revenue does not automatically mean a profitable protocol.
Example
A lending market collects 10 million dollars of borrower interest in a year, passes 9 million to depositors and keeps 1 million as a reserve factor; that 1 million is its protocol revenue.
