About 82% of this 1.63% APY is decaying token emissions. The real fee yield is ~0.30%. It is single-asset, so there is no impermanent loss to drag you below holding.
Real fee/staking yield: 0.30% · token emissions: 82% of the headline.
No impermanent loss here, so you keep the same price exposure either way. The honest number is the ~0.30% of real yield — the rest is fading emissions, not income.
