About 99% of this 28.3% APY is decaying token emissions. The real fee yield is ~0.16%. This pool is short volatility — fees stop covering impermanent loss if WETH-AERO diverges more than ±12%.
Real fee/staking yield: 0.16% · token emissions: 99% of the headline.
Break-even fact: a ±12% move in WETH-AERO erases a full year of the fees you actually keep (~0.16%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
