About 16% of this 6.43% APY is decaying token emissions. The real staking / lending yield is ~5.37%. It is single-asset, so there is no impermanent loss to drag you below holding.
Real fee/staking yield: 5.37% · token emissions: 16% of the headline.
No impermanent loss here, so you keep the same price exposure either way. The honest number is the ~5.37% of real yield — the rest is fading emissions, not income.
