About 93% of this 6.64% APY is decaying token emissions. The real fee yield is ~0.49%. This pool is short volatility — fees stop covering impermanent loss if WETH-CVX diverges more than ±22%.
Real fee/staking yield: 0.49% · token emissions: 93% of the headline.
Break-even fact: a ±22% move in WETH-CVX erases a full year of the fees you actually keep (~0.49%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
