The token that pays real stocks to whoever holds it.

01

Introduction

Bucket Shop is a payout system on Robinhood Chain built around one token, BUCKET. Every trade of BUCKET against ETH pays a 3% fee into a Treasury. A keeper turns that ETH into tokenized stocks and crypto and sends them to holders in proportion to what they hold. The stocks are the same tokens Robinhood issues on its chain, held in the holder's own wallet, tradeable the moment they land.

Around that core sit five things that use the same engine: Buckets, which let a holder choose which basket they are paid in; Buckethead cards, on-chain wallets that concentrate a holder's payout on the assets they pick, with a multiplier for rarer cards; a launchpad where any token can be launched to pay its own holders the same way; Stockback, a swap router that returns half its fee as stocks; and XCORP, a token backed by TSLA and SPCX that pays BUCKET holders from its pool fee.

Most of the system is code with no owner. The part that is not, the keeper that decides what to buy and when to settle, is described here without euphemism, and the full list of what an owner key can change is on the rules page.

02

The entities and how they relate

There are twelve. Everything in the system is a relationship between them.

The mental model: the pool is the tap, the Treasury is the bucket, the engine is the hand that pours. Everything else decides where the water lands.

The flows between them:

• Traders ⇄ pool. Anyone can buy or sell BUCKET, no account needed. Every swap pays the hook 3% in ETH, on both sides.
• Pools → Treasury. The ETH pool's hook credits its fee straight to the Treasury. The USDG pool's hook pays a fee vault, and the keeper converts that to ETH for the Treasury each cycle. Together with launchpad fees, this is the engine's income.
• Treasury → engine. Each epoch the keeper pulls the available fee ETH, sets aside 10% for a buyback, and spends the rest on the assets holders have chosen.
• Engine → holders. Purchases are credited to holders pro rata by BUCKET held, weighted by any card they own. When a holder's jar reaches $2 it is delivered as the asset itself.
• Holders → engine. A holder's Bucket choice and card moves tell the engine what to buy for them. Nothing else about the payout is configurable.
• Launchpad → engine. A token launched on the pad pays the same engine from its own trade fees, and the engine buys the stock its creator chose for that token's holders.
• Engine → pool. The buyback leg buys BUCKET with ETH and burns it, capped per tick at 0.2% of the pool's reserve.

03

The fee and the engine

The fee is 300 basis points, written as a constant in the pool hook. It cannot be raised, lowered, paused or redirected. It applies to buys and sells alike, so a sell day funds Drops exactly as a buy day does.

The engine is our keeper: a program on a server that signs with the protocol's owner key every five minutes. In each cycle it collects fees the hook has credited, reads the current holder set, computes each holder's share, buys the assets those shares call for, issues Bucket shares against what it bought, and settles an epoch. An epoch settles whenever at least 0.001 ETH of fees is available, so at normal volume epochs run every few minutes and at low volume they wait.

Where each epoch's cut goes

Every epoch, from the fee ETH available at that moment. The buyback leg buys BUCKET and burns it, capped per tick at 0.2% of the pool's reserve.

What is enforced on chain and what is not

We would rather you know exactly which steps are ours than read "trustless" and find out later.

Drops

A Drop is a delivery. Your share of every epoch accrues in a jar. When the jar reaches $2 the keeper sends the assets in it to your wallet. There is no claim, no unwrapping and no expiry. If you hold a card, the card's line accrues separately and delivers on its own clock, as the exact asset the card picked.

• 01
  EligibilityHold at least 10,000 BUCKET. The floor is a constant in the Distributor and is checked on chain for every recipient.
• 02
  ShareYour weight is your BUCKET balance, multiplied by any card budget, capped at the card's published ceiling. A volume ladder adds up to 2x for wallets that traded in the window.
• 03
  DeliveryAt $2 the jar is paid as the asset itself: stocks, crypto, or the Bucket's basket, according to your choice. Early Drops were paid as Bucket shares; those remain redeemable for their stocks at any time.

Everything the engine has ever delivered is public. The Earn page lists every transfer, and each one is a transaction on Robinhood Chain that anyone can verify.

05

Buckets

A Bucket is a themed basket. Choosing one tells the engine which basket to buy for you. There are six: Core, Big Tech, Chips & AI, Degen, Broad Market and Crypto. Each is a vault contract with its composition fixed at deployment, no owner, and no way to pause redemption. The engine can only add assets and mint fully backed shares; it cannot take anything out.

Your choice is one free-to-change slot per wallet, recorded on chain. Which basket a slot number maps to is keeper configuration; the vaults themselves are what hold the assets.

06

Buckethead cards

A Buckethead is an NFT that is also a wallet. It holds its own stocks, and it tells the engine where its owner's payout should concentrate. Rarer cards carry a larger budget.

All four series are minted out. Series C's 251 cards also share a revenue seat contract: every deposit to it splits across all 251, and only a card's owner can claim its seat.

07

The launchpad

Anyone can launch a token that pays its holders in real stocks. The creator picks a quote asset from a frozen list of 193 (USDG and the tokenized stocks), a trade fee between 1% and 5%, and which stock the holder leg buys. The token sells on a bonding curve; when the curve is bought out it graduates into a plain Uniswap v4 pool, which the Robinhood app's own router can trade, with the liquidity locked permanently.

Where a launched token's fee goes

BLOX, a live launch with a 3% fee, as its creator set it: holders, the token's own backing, buyback, locked liquidity (5%), creator. The launchpad's take is carved from the first 1% before this split and cannot exceed the 31% ceiling.

The factory itself has been sealed: its quote list cannot grow and it has no owner. Adding a quote asset means deploying a new factory, which every wallet would see.

08

Stockback

Stockback is a swap router for any token on Robinhood Chain. Token swaps pay a flat 0.5% router fee per hop, and half of it is credited to the trader's jar and paid out as stocks by the same engine. Legs that touch a tokenized stock route through a separate router whose fee is zero, so securities trades carry no router fee and no rebate.

Each router's fee is immutable in its contract, with a 1% ceiling enforced at construction. A different rate is a different address.

09

XCORP

XCORP is a token backed by tokenized TSLA and SPCX. Anyone can deposit the pair to mint it or redeem it pro rata for the backing; the contract has no owner, no mint and no tax. It trades in a plain pool with a 3% LP fee on a locked position. The keeper collects that fee and splits it: 1.5% to BUCKET holders through the engine, 1.5% into XCORP's own backing.

The pool's 3% fee, collected hourly by the keeper. The 3% itself is locked in the pool; the split is keeper policy.

10

Buybacks and burns

Ten percent of every epoch's fee cut buys BUCKET and burns it. Since 15 September 2026 the buy is rate-limited per tick to the smaller of 10% of the cut or 0.2% of the pool's ETH reserve, so the protocol cannot be baited into spending its reserve into a dump; anything clipped carries to the next tick. Series D ascensions and trench reinforcements burn BUCKET too, to the dead address, at 25,000 to 150,000 per ascension.

BUCKET has no burn function, so burned tokens are parked at the dead address rather than removed from total supply. The effect on circulating supply is the same.

11

Where the money goes

Every fee the protocol takes, the contract that takes it, the hub it passes through, and where it lands. Line colour is the destination: green reaches a holder, pink a trader, purple locked liquidity, amber a creator, red the dead address, grey a seller. Thickness is the size of the flow.

12

Flywheels

Three loops, each one closing on the pool.

• 01
  Trade → stocks → holdFees buy stocks. Stocks arriving in wallets are the reason to hold. Holding thins the float, so the next trade moves price more and pays each remaining holder a larger share of the next Drop.
• 02
  Launch → the same engine → more DropsEvery token launched on the pad pays the engine from its own trades. More launches mean more fee sources for one engine, and each graduate's holders are buying the stock their creator chose, through us.
• 03
  Cut → buyback → burnTen percent of every cut buys BUCKET and burns it, and every Lord ascension burns more. Supply only falls; the fee that funds the burn only rises with volume.

13

What can change, and who can change it

Every parameter in the protocol falls into one of four classes. The full table is its own page; the shape of it is this.

Risks, stated plainly

• 01
  One keyEvery owned contract is owned by a single key that also runs the keeper. It has not been renounced and sits behind no multisig or timelock. Moving it behind a multisig is the next step once Bucket Labs LLC is formed.
• 02
  The keeper is software we runIf it stops, Drops stop until it restarts; fees keep accruing in the Treasury and are not lost. If it were wrong, the ledger would show it.
• 03
  The stocks are Robinhood's tokensTokenized stocks on Robinhood Chain are issued by Robinhood Assets (Jersey) and are restricted for US persons under the issuer's terms. On chain they are plain ERC-20s. Whether you may hold them is your responsibility.
• 04
  Drops depend on volumeEvery Drop is funded by trading. A quiet day pays little. Nothing here is a yield, a dividend or a promise.
• 05
  Contract riskThe launchpad contracts are under audit by SB Security from 16 September 2026, with the report published here when complete. The core contracts have been reviewed internally and are verified on Blockscout. Code can still have bugs.
