You're being paid 4.87% to absorb price risk. Only ~4.87% of it is real fees — and they stop covering impermanent loss if GROVE-BBQUSDC diverges more than ±89%.
Real fee/staking yield: 4.87% · token emissions: 0% of the headline.
Break-even fact: a ±89% move in GROVE-BBQUSDC erases a full year of the fees you actually keep (~4.87%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
