Every part of Beanhood, written down

01What it is

The token $BEAN trades in a pool that charges 1% on every swap. 70% of that fee is the creator share, which works out to 0.7% of traded volume. It arrives in two assets, roughly half WETH, half $BEAN.

The WETH is spent on four tokenized stocks and credited to every NFT in the collection by weight. The $BEAN is sent to the creator wallet and burned in batches.

Seven trait categories: Background, Body, Outfit, Mouth, Eyes, Headwear and Tier. Six of them are appearance. The seventh, Tier, is the only one that touches money.

Bodies are materials rather than skin tones — Dough, Clay, Sand, Ash, Moss, Emberskin, Frostbitten, Gilded. Every one of the 4,444 combinations appears exactly once; both the images and the trait sets were checked for duplicates by hash before anything was uploaded.

04Tier and weight

Payouts divide by weight, not per head. Tier is written into the metadata before mint, and the payroll stores it as three bits per token id — loaded once, then sealed permanently.

Weight cannot be raised. There is no burn-to-boost, no staking multiplier and no upgrade path. A Legendary earns twelve times a Common in every round, and there will never be a forty-fifth Legendary.

Assignment

Randomdrawn at mint

Payment

ETHnative, no approval

Token ids are drawn at random from whatever is unminted, using a lazy Fisher-Yates shuffle that touches two storage slots per draw — the last mint costs the same as the first.

The randomness exists because the metadata is public before mint. A sequential mint would hand all 44 Legendaries to whichever bot read the file fastest.

06The payroll

It is deployed after $BEAN launches, not before. The contract takes the token's address in its constructor and keeps it forever, and the function that moves the token half out is open to anyone — so pointing it at a placeholder would let the first caller drain whatever that placeholder turned out to be.

WETH accumulates in the payroll contract. Once the balance clears MIN_ROUND, anyone may call convert(), which buys all four stocks in equal quarters and credits every token at once.

Crediting uses an accumulator rather than a loop. Each purchase raises a single number per stock — earnings per unit of weight — and a token's balance is its weight multiplied by that number, minus whatever it has already withdrawn. A round therefore costs the same whether one bean exists or all 4,444 do, and no round is ever too small to pay everybody. Paying 4,444 tokens across four stocks the naive way would be 17,776 transfers.

08The route

Stocks on Robinhood Chain are quoted against USDG, not against ether. A direct WETH swap would route through almost nothing — the WETH/SPCX pool holds 0.0003 ETH while its USDG pool holds over half a million. Every purchase therefore takes two hops, and the path is fixed in the contract.

WETH --0.01%--> USDG --0.05%--> NVDA      629,496 USDG deep
                     --0.30%--> SPCX      505,002

Call pathTo(index) to read the exact bytes handed to the router. Nobody has to take our word for where the money goes.

09Claiming

Stock is credited to the token, not to the wallet that held it when the round ran. claim(tokenId) transfers everything owed to the current owner; claimMany(ids) does several at once. Both are optional and there is no deadline.

Unclaimed stock therefore travels with the NFT. A bean that has never been claimed carries its whole accumulated balance to whoever buys it next — worth checking before you list, and worth checking before you buy.

The holdings page reads what each of your beans is owed and claims them in one transaction.

Creator share

70%of the pool fee

Until $BEAN is trading there is no pool, no fee and no round. The creator share is set at launch and cannot be changed afterwards.

The token half of the fees is held in the creator wallet and burned in batches.

11Every function

There is no setOwner, no setFee, no withdraw on the payroll and no upgrade path. The list above is complete.

The basket

Several tokens on this chain share these symbols. The four below are the official Robinhood Token contracts and are immutable in the payroll — they are the only four it can ever buy.

14What cannot change

• The payroll has no owner, no setter and no upgrade path. Nothing in these docs can be altered after deployment, including by us.
• Stock addresses, the swap route and the pool fee tiers are immutable, set in the constructor.
• The tier table can be written only by the deploying address, only before sealing, and never again. convert() refuses to run until it is sealed, so no round can happen against a half-written table.
• convert() is permissionless, so the payroll cannot be stopped by the team losing interest.
• Slippage limits come from the caller, from a live quote, rather than being frozen at deployment.
• The $BEAN half of the fees can only ever move to one address, fixed at deployment.
• No audit. The contracts compile clean, but no third party has reviewed them.

15Known limits

Stated here rather than discovered later.

• No fees until the token trades. Nothing accrues before $BEAN has a live market, and if it never gets one there is never a payroll.
• Payout tracks volume. At low volume a round can be worth less than the gas required to claim it.
• The $BEAN half is held, not burned on arrival. It goes to the creator wallet and is burned in batches. The destination is fixed at deployment; the timing is not. This is the one part of the system that still requires trust, and the wallet is public so it can be watched.
• Stock can fall. The payroll buys at market price. It accumulates stock; it does not promise the stock rises.
• Smart wallets cannot mint, for the reason given in section 05.
• Royalties are not enforceable. ERC-2981 is honoured at each marketplace's discretion.
• Unaudited and immutable at once. A bug found later cannot be patched later. Mint small.

16Disclaimer

Beanhood is an experimental on-chain collectible. Nothing here is investment advice and no return of any kind is promised. Tokenized stock is a token that tracks a stock price; it is not the stock itself, and it carries the risks of both.

Buy only what you are willing to lose.
