The shoe is sealed before you're dealt

Same commit-and-reveal as the poker tables. Before your first card, the hash of the shoe's seed is written to the chain. When the hand ends the seed is published and has to match. Your client seed goes into the mix too, so neither side alone decides the order.

Six decks reshuffled every hand means counting won't get you anywhere — but neither will anyone dealing a card that wasn't already in the sealed shoe.

Blackjack is played against us

Worth saying plainly. At the poker tables we take 2.5% of the pot and don't care who wins. At blackjack you're playing against the house bankroll, so when you lose, we're on the other side of it. The 0.43% edge is where that money comes from, which is why the rules on the left are worth reading first.

Cashier

Your address appears when you log in

Every player gets their own wallet on Robinhood Chain, created the moment you register. Nobody shares a deposit address here.

Cashing out

Withdraw between hands to any Robinhood Chain address — it doesn't have to be the one you deposited from. No minimum, no ticket, nobody to ask. Requests under the threshold go out automatically; larger ones get a look from a human, usually within the hour.

Don't have any HOUSEFLY yet?

Every seat in the building is priced in HOUSEFLY, so that's the only thing the cashier takes. Holding ETH or USDG on Robinhood Chain? Swap it on chain first — one transaction, a few cents of gas — then send here.

Holding a bankroll in one token cuts both ways: chips you aren't playing still move with the market while they sit here. That risk is yours, not ours. Withdraw what you're not using.

How it's made

Registering creates a wallet for you through Turnkey, which generates and holds the private key inside a secure enclave. The key is never shown to you, never sent to your browser, and never sits on our servers. Your passkey — Face ID, Touch ID, a security key — is what authorises it.

That wallet's address is your deposit address, and it stays the same for as long as the account exists. Save it, label it, send to it from an exchange.

What that does and doesn't mean

An address of your own is not the same as self-custody. Once HOUSEFLY arrives it's swept into the house bankroll, and your balance here is a number we owe you. Withdrawing sends real tokens back out to any address you name.

The upside is that your deposits and payouts are individually traceable on the explorer instead of pooled with everyone else's. Your own record, not just ours.

Provable fairness — nothing up the sleeve

Sealed before it's dealt

Before any card goes out — poker table or blackjack shoe — the hash of a secret seed is written to the chain. When the hand settles the seed is published, and it has to match the hash already sitting there. Your browser can rebuild the order and confirm every card came from the sealed deck. Each settled hand carries a Verify button.

Where your balance sits

This is a custodial room. Between your deposit and your withdrawal, housefly.fun holds your HOUSEFLY. Most of the bankroll sits in cold storage; a hot wallet covers the tables. Two risks to weigh, not one: we hold the tokens, and the tokens themselves move in price.

Two games, two houses

At the poker tables we take 2.5% of pots that see a flop and have no stake in who wins. At blackjack we are the other side of your bet, and the house edge is the business model. Same sealed shuffle and same token either way, but it's worth knowing which chair you're in.

The deck is sealed
A hash of the seed goes on chain before the first card. Once written, the deck it describes can't be swapped for a friendlier one.
Cards come out of the seed
Hole cards, board, blackjack shoe — all derived from the sealed seed and your client seed by a published algorithm. Nothing is drawn after the fact.
You just play
No popups, no signatures, no gas. Thirty seconds on the poker clock; blackjack moves at your pace.
The seed is published at settlement
Checked against the hash that's been on chain since before the deal, then the hand pays out.
You rebuild the deck yourself
Open the hand, hit Verify, and the check runs in your browser. Every hand ever settled here stays readable, including everyone else's.

$HOUSEFLY

Every chip on the floor is the token.

One currency, everywhere. Poker pots, blackjack hands, buy-ins, payouts — all HOUSEFLY, which means every unit of rake and every point of house edge arrives already denominated in the token. Nothing to convert, no treasury buying to trust.

So it goes straight to the burn address. All of it, every day, as a public transaction on Robinhood Chain. You don't have to take our word for the supply curve; you can read it.

Burned, not banked

Rake is 2.5% of flopped pots. The blackjack edge is 0.43% of what's wagered. Neither is held, staked or paid out to anybody — it's sent to a burn address you can watch, and supply only goes one way.

Rake goes up in smoke
