You're being paid 0.78% to absorb price risk. Only ~0.78% of it is real fees — and they stop covering impermanent loss if LON-WETH diverges more than ±29%.
Real fee/staking yield: 0.78% · token emissions: 0% of the headline.
Break-even fact: a ±29% move in LON-WETH erases a full year of the fees you actually keep (~0.78%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
