Made to fill
Capital on the curve is only worth something if it can be taken. So it can be taken in pieces, in bands, and across a range, and none of it gets stuck.
- Slices
Take any part of a floor
One commitment serves many holders. Take $10 of it or all of it: each slice is its own claim, with its own collateral, priced pro rata against what the maker escrowed.
Buy a floor → - Sweep
A band of protection, one approval
Ask for $150 and it fills across floors, cheapest premium first, packed into as few transactions as will fit.
Sweep a band → - Ladder
Commit across a range
Spread USDC from one valuation to another in one approval: evenly, or with more at the lower valuations you would rather own at.
Build a ladder → - Your book
Run it like a book
What holders took, what is still on offer, what the premium paid and your capital over time. Withdraw what nobody took; settle what has run out.

Nothing waits on a counterparty
Past its deadline, anyone may settle a claim: the maker’s USDC and the holder’s tokens go home, and nothing else can move. A keeper does it for everyone every ten minutes, and because anyone may, nobody depends on the keeper either.
The protocol’s cut comes out of the premium, is capped at 5% by the program, and is never taken from collateral.

Percentage is the market’s premium or discount to the PreStocks reference mark. A mark is a reference, not a fair value.
Infrastructure for honest private valuations
Commit capital, surface a demand curve, and let holders buy a floor — without an oracle in the settlement path.
Capital that actually shows up
Horizontal bars of USDC locked at each valuation band. Peak bands use amber; concentration is shown inline so one wallet cannot dress up as a market.
Keep the upside, buy a floor
Holders lock PreStocks, pay a premium, and may exchange them for the committed USDC before expiry.
No oracle required
Strike is fixed at creation. Exercise is the holder’s choice — Rung never asks a feed whether it is rational.
Vaults, stated plainly
Collateral sits in program vaults. Issuer mint powers still apply — read the limitations.
