About 73% of this 21.2% APY is decaying token emissions. The real fee yield is ~5.62%. This pool is short volatility — a two-token pair, so impermanent loss can quietly erode your return.
Real fee/staking yield: 5.62% · token emissions: 73% of the headline.
Most of this headline is fading emissions, not income. Judge the pool on what you'd actually keep — ~5.62% — not the advertised APY.
