You're being paid 0.63% to absorb price risk. Only ~0.63% of it is real fees — and they stop covering impermanent loss if USDC-VULT diverges more than the pair moves.
Real fee/staking yield: 0.63% · token emissions: 0% of the headline.
The real fees here (~0.63%) can beat holding if USDC-VULT stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
