THE RATE WANDERS
A stable pair moves away from its intended exchange rate.
A stable pair drifts. Arbitrage bots reach for the value. The hook scales the fee. LPs get paid.

Illustrative interaction only. It does not reproduce or quote the deployed StablePair Hook fee curve.
The Meme is simple because the mechanism is simple enough to see.
A stable pair moves away from its intended exchange rate.
Arbitrage activity arrives to trade the difference.
StablePair Hook adjusts the LP fee as the drift changes.
Swap fees accrue directly to the pool's liquidity providers.
A fixed fee cannot react when the value of correcting a drift changes.
The fee can adapt at swap time, capturing more of the opportunity for LPs.
Yoinky sleeps beside the $1 peg. When a stable pair starts wandering, one eye opens. When a bot reaches in, Yoinky does what Yoinky does.
