01 / 08 · The floor live simulation · 3d

Price can go anywhere. Settlement can't go below the floor.

Every bar is one block of spot on a random walk at the asset's own implied vol. The glowing plane is the strike you chose. Bars that fall through it get clamped and turn yellow — that is the protocol paying the difference. Drag the strike and watch the protected region change.

White bars settle at spot. Yellow bars were caught by the floor — the grey stub behind each one is where it would have settled without it.

02 / 08 · Trade quotes update per block

Open a floor in one block.

Pick the asset, drag the strike, and the premium reprices live. Deeper floors cost less because they sit further from spot. Tighter floors cost more. Nothing here is a calendar.

03 / 08 · Payoff position value vs spot · 3d

The kink is the whole product.

Two positions in the same stock. The white line is holding it naked — it tracks spot all the way to zero. The yellow line is the same holding with a floor open: identical above the strike, flat below it. You pay premium for the corner.

FLOOR AT $159.29

Above the strike the two lines are the same position — a floor never caps upside. Below it, one keeps falling and one stops.

Sell it, carry it, or chute it.

Every holder of a tokenized equity has had exactly two moves. This is the third, and it is the only one that lets you keep the position you were right about.

01

You set the floor

Pick any strike from 70% to 95% of spot. That price becomes the level your position cannot settle below, for as long as you keep paying.

Priced per block

Premium is metered block by block, not sold in monthly slabs. Stop paying and the floor closes in the next block. You are never buying time you will not use.

No calendar

A floor opens in one block and closes in one block. There is no expiry to diarise, no roll to get wrong, and no third Friday.

No liquidation engine

Writers are fully collateralised in USDG before a floor opens. Settlement is an oracle read against Chainlink. There is nothing to unwind and nobody to margin call.

06 / 08 · Lifecycle open → accrue → settle → close

Four states. Every one of them is a single block.

Four parachutes in sequence from packed to fully inflated
01 · OPENPackedYou name a strike and a notional. The contract locks a writer's collateral and the floor is live in the next block.
02 · ACCRUEDeployingPremium is pulled from your prepaid balance every block. Top it up or let it run down — the floor closes when it empties.
03 · SETTLEInflatingIf the oracle prints below your strike, the contract pays the difference in USDG. You never had to sell anything.
04 · CLOSEOpenClose it whenever. Unused prepaid premium comes back and the writer's collateral is released in the same block.
07 / 08 · Underwrite the other side of the book

Write floors. Get paid every block.

Somebody has to be under the falling cube. Writers deposit USDG into a per-asset pool, the pool backs floors at 100% collateral, and 92% of every block's premium flows straight back to depositors. No leverage anywhere in the system, so no cascade to be caught in.

Collateral first, floor second

A floor cannot open unless a pool has already posted the full difference between spot and the strike. That is the entire risk model — no health factor, no maintenance margin, no keeper network, because nothing in the system can become undercollateralised.

Settlement is a read, not a race

When a floor is exercised the contract asks Chainlink for one price and pays the difference in USDG. No auction, no keeper incentive to win, no partial fill. The same read settles every floor on that asset in the same block, so nobody is front-running anybody.

Where the premium goes

Every block's premium is cut once. Ninety-two percent lands in the writer pool that is carrying your floor; eight percent is the protocol fee. There is no sequencer tip, no keeper bounty and no spread hidden in the quote — the number in the terminal is the number that leaves your balance.

92%To the writer pool

Twenty-six rungs, one at a time

The strike is an integer percent of spot from 70 to 95, so there are twenty-six levels to pick from and no strike ladder to hunt through. Move down a rung and the premium drops because the floor sits further from spot; move up and it climbs. One floor per position per asset.

Settlementnetwork details

CHUTE settles on Robinhood Chain.

Robinhood Chain is a USDG-native Arbitrum Orbit L2, chain id 4663, fully EVM equivalent. Premium, collateral and settlement all move in USDG on the same chain the tokenized assets live on — nothing bridges to close a floor.

Questions the ones that actually get asked

What people ask before they open one.

Does a floor cap my upside?

No. A floor only changes what happens below the strike. Above it your position behaves exactly as it did before — you own the same tokenized share and you keep all of the move. The only cost is the premium accruing per block.

What happens if I stop paying?

The floor closes at the next block and the writer's collateral is released. Nothing is seized, nothing is liquidated, and your underlying position is untouched. You are simply unprotected from that block onward, and you can open a new floor whenever you want.

Why is the weekend so much more expensive?

Because the underlying stops trading and the gap risk does not. A floor written into a closed session has to price the possibility that Monday opens well below Friday's close, with no chance to reprice in between. Across the four launch markets the closed rate runs about 2.25× the weekday rate.

Who is on the other side?

A per-asset writer pool, funded by depositors who want the premium stream. The pool posts 100% of the potential payout as collateral before your floor opens, which is why there is no liquidation engine anywhere in the design.

How is this different from buying a put?

A put has an expiry, a strike ladder, a roll, and a premium you pay in one lump for time you may not use. A floor has none of those. It opens in a block, meters premium by the block, and closes in a block — protection as a subscription rather than a dated contract.

Is there a token?

Nothing has been announced. The protocol is in preview on testnet and this site will say so plainly until that changes.
