You're being paid 12.9% to absorb price risk. Only ~12.9% of it is real fees — and they stop covering impermanent loss if MNT-USDE diverges more than the pair moves.
Real fee/staking yield: 12.9% · token emissions: 0% of the headline.
The real fees here (~12.9%) can beat holding if MNT-USDE stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
