About 82% of this 4.94% APY is decaying token emissions. The real fee yield is ~0.90%. This pool is short volatility — fees stop covering impermanent loss if USDC-WBTC-WETH diverges more than ±31%.
Real fee/staking yield: 0.90% · token emissions: 82% of the headline.
Break-even fact: a ±31% move in USDC-WBTC-WETH erases a full year of the fees you actually keep (~0.90%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
