Perigee — Stable Swap
PERIGEE
STABLE SWAP

Minimum
Distance

An AMM for assets that are supposed to be worth the same. The curve is deliberately flat, so institutional size crosses at parity — and crosses without being seen first.

Size in.
Parity out.

One instrument, four pegged books. Quote, impact and route resolve before you commit — nothing leaves the panel until you do.

Slippage is
a design choice

A general-purpose curve bends everywhere because it must price anything. Ours bends only at the edges. Drag the amplifier and watch the flat band open up.

Size that cannot
be seen first

A flat curve is worthless if the market reads your intent on the way in. Perigee quotes and settles without publishing the order that produced it.

Four orbits.
One apsis.

Every pegged pair traces its own ellipse. The tighter the orbit, the smaller the band you ever pay to cross it.

Whole,
or not at all

Three stages, one commitment. Nothing half-settles, nothing sits exposed between legs.

Depth
gets paid

Single-sided deposits, no impermanent loss between pegged legs, fees accrued per crossing. The flatter the curve, the harder each unit of depth works.

Cross at the closest point

The default venue for moving between pegged assets — flat, discreet, atomic.
