Aerodrome is changing how it pays for liquidity. Emissions are paid in AERO while fees come in as dollars, so when AERO rises, the protocol gets less profitable if fees don't outpace the price. Every week it mints new tokens that are paid to liquidity providers, which is a real cost to the business. Aerodrome aims to fix this with the AER Engine, which pegs emissions to revenue instead of the token price and caps inflation within a set band. Spend follows what the protocol earns rather than what the token does, so a rising AERO price no longer mechanically pushes earnings down. It also changes the shape of the cost line. A fixed weekly mint held spending flat regardless of what the protocol brought in. Linking emissions to fees replaces that with a cost that scales with the business.(Delphi Digital)
