You're being paid 3.15% to absorb price risk. Only ~3.15% of it is real fees — and they stop covering impermanent loss if MPLX-WSOL diverges more than the pair moves.
Real fee/staking yield: 3.15% · token emissions: 0% of the headline.
The real fees here (~3.15%) can beat holding if MPLX-WSOL stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
