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 MPLX-WSOL diverges more than the pair moves.
Real fee/staking yield: 4.27% · token emissions: 0% of the headline.
The real fees here (~4.27%) can beat holding if MPLX-WSOL stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
