About 93% of this 1.67% APY is decaying token emissions. The real fee yield is ~0.12%. This pool is short volatility — fees stop covering impermanent loss if USDT-WBTC-WETH diverges more than ±10%.
Real fee/staking yield: 0.12% · token emissions: 93% of the headline.
Break-even fact: a ±10% move in USDT-WBTC-WETH erases a full year of the fees you actually keep (~0.12%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
