About 28% of this 6.42% APY is decaying token emissions. The real staking / lending yield is ~4.60%. It is single-asset, so there is no impermanent loss to drag you below holding.
Real fee/staking yield: 4.60% · token emissions: 28% of the headline.
No impermanent loss here, so you keep the same price exposure either way. The honest number is the ~4.60% of real yield — the rest is fading emissions, not income.
