You're being paid 4.27% to absorb price risk. Only ~4.27% of it is real fees — and they stop covering impermanent loss if USDC-WETH diverges more than ±81%.
Real fee/staking yield: 4.27% · token emissions: 0% of the headline.
Break-even fact: a ±81% move in USDC-WETH erases a full year of the fees you actually keep (~4.27%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
