Built on Robinhood Chain

Nobody
counts a
stack.

Twelve notes a band, every one a real amount of tokenized cash. You don't find out what they're worth until the strap breaks. Buy it, snap it, keep what falls out.

A stack is what money looks like when it stops being a number on a screen. This one is strapped on chain — twelve notes, one band, denominations you can't see through the paper.

Make it rain

Break a band Read the rulebook

Notes settle in USDG, the native unit of Robinhood Chain. Every note is cash the vault already holds — nothing is printed on top of it.

The mechanic

Three steps. One of them is breaking a strap.

No bonding curve, no waiting list, no points. You buy a band, you break the strap, and what was inside is yours.

  1. 01

    Buy a band

    Twelve notes, strapped. The denominations are committed on chain before you pay, so nobody — you included — knows what the band counts to.

  2. 02

    Snap the strap

    One transaction breaks the band. You are opening the band you bought, not one counted after the fact.

  3. 03

    Count it out

    Every note lands in your wallet as spendable USDG. No claim step, no vesting, no waiting for a snapshot.

What's in the band

Every note in here is real cash.

Not a points balance, not a receipt. The whole band is USDG the vault already bought — sorted by how much of it is on the paper, and the vault's cash on hand is the ceiling on how many hundreds exist.

Example distribution — illustrative, not a live contract parameter. A denomination only appears in a band once the vault holds enough cash to cover it.

Proof of vault

Nothing is printed. A band only straps if the vault can fill it.

In this example the vault holds no hundreds, so no hundred can be strapped. Bands keep pouring the other four denominations until the vault buys more.

The stackdex

Seven faces. Two to go.

Every note you count out fills a slot. Complete a face's twelve and the set burns for the whole band — the rest just sit there being annoying.

The vault is the only source of notes and the only limit on them. Everything else — denomination odds, band size, the burn — is fixed in the contract and public before you buy.

Questions

The honest answers.

Why cash and not stocks?

Because cash is the one asset that needs no explaining. A stack is worth what it counts to, in the unit the chain already runs on. There is no ticker to look up, no price feed to argue with, and no gap between what a note says and what it pays.

Why "Stack"?

A stack is what money looks like when it stops being a number. Paper, banded, in your hand. Twelve notes to a band, denominations you cannot see through the strap, and nobody counts it until the strap breaks.

Do I own actual dollars?

You own USDG — the native unit of Robinhood Chain, and the same asset the vault holds. Nothing is wrapped, printed or IOU'd on top of it. What lands in your wallet when a band opens is spendable the moment it arrives.

What stops you strapping a band you cannot fill?

The vault. A band can only be strapped against cash the vault already holds, and the vault's balance is a public address. When it runs out, bands stop until it refills.

Can a band be empty?

No. Twelve notes, every time. What varies is the denomination, and the denomination is what decides how much cash is on the note.

What happens if I complete a face?

Twelve notes of one face burn as a set and pay out the whole band in one go, instead of leaving you holding twelve loose notes.

Settled on Robinhood Chain

Break a strap. See what it counts to.

Twelve notes, four denominations, one hundred in twenty. The vault's cash on hand is the only limit on how many bands exist.
