You're being paid 6.78% to absorb price risk. Only ~6.78% of it is real fees — and they stop covering impermanent loss if OPAL-WETH diverges more than ±114%.
Real fee/staking yield: 6.78% · token emissions: 0% of the headline.
Break-even fact: a ±114% move in OPAL-WETH erases a full year of the fees you actually keep (~6.78%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
