About 89% of this 3.97% APY is decaying token emissions. The real fee yield is ~0.46%. This pool is short volatility — fees stop covering impermanent loss if USD₮0-USDC.E diverges more than ±21%.
Real fee/staking yield: 0.46% · token emissions: 89% of the headline.
Break-even fact: a ±21% move in USD₮0-USDC.E erases a full year of the fees you actually keep (~0.46%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
