Gas & fees

Two different things get confused a lot: gas (the network's fee to run a transaction) and the cabinet fee (the swap fee that funds the floor). Here's who pays what, and where it goes.

Gas — who pays for each action

Base is a low-cost network, but every on-chain action still costs a little gas, paid by whoever sends it:

• Playing (buy / cash out): you pay the gas for your own swap. Normal wallet behavior — nothing unusual.
• Claiming a prize: the winner pays the small gas to claim. The prize itself isn't touched by it.
• Running the floor (buybacks, refills, batching): the House pays the gas for its own machinery — the keeper that harvests fees, tops up the pots, and buys back. That cost is never passed to players.

The House's keeper is built to be cheap: it does nothing (a free read) when there's nothing to do, and when it acts it batches everything into one transaction, so a quiet stretch on the floor costs the House almost nothing to keep running.

The machine pays its own electric bill

The keeper's gas doesn't depend on anyone remembering to top up a wallet — the floor greases itself, and it does it from the House's own cut:

• The House's 10% cut arrives in the mother's pair — WETH — and the floor counts it in sats. When the keeper harvests, the tank keeps only what the gas gauge needs as ETH (WETH unwrapped, no exchange involved) — and only until the tank is full (a fixed target that covers months of operation). Everything past the target flows to the treasury as normal.
• The floor's 90% is never touched. Not one basis point of the players' split pays for gas — the House's own 10% covers its own machinery.
• No coin is ever sold. The tank only ever touches the cash side of the harvest (sats → gas). No cabinet's coin — not COIN-OP, not any machine's — is dumped on any pool to buy gas, ever.
• The tank address is public and capped by construction: every top-up is an ordinary on-chain transfer anyone can audit, and a full tank takes nothing.

So the machine keeps running — harvests, refills, buybacks, burns — even if the operator disappears for a month. The lights stay on because the venue's own cut pays the electric bill, automatically.

The cabinet fee — where it goes

Every buy and sell pays a small swap fee. That fee is the floor's fuel. It splits on a fixed, published schedule:

• 10% — the creator. The person who put the cabinet on the floor.
• 90% — the floor, split four ways:
  • 40% — REFILL: the machine buys back its own coin and burns it.
  • 30% — HIGH SCORE: the prize stream for that cabinet's own board.
  • 15% — JACKPOT: that cabinet's own pot — when it trips it buys its own coin back and burns it, and 10% of the pot goes to the prize counter.
  • 15% — RENT: the House's, for the spot on the floor. It stocks the PRIZE COUNTER and fills the bar on THE CLAW.

This split is the same on every cabinet, and it's why the floor feeds itself: every coin played moves every meter. The REFILL stream is the flywheel — the House buys back and burns with the fees the floor generates, so activity tightens supply.

The fee funds a game and its prizes. It is not a dividend and not a yield — playing is entertainment, and the pots are part of the show.

Verifiable

Fee splits, buybacks, burns, and every pot balance are on-chain and readable. The site shows them live; you never have to take the numbers on faith.
