A mining game on Robinhood Chain.
Mint a graphics card for $5, slot it into your rig, and it earns $GPU for as long as it's plugged in.

$GPU CA: 0x3Da22F970a0a048d3830fDE22b94017B83a3802E

$GPU is never minted. Only bought.

The game

10,000 graphics cards, $5 each. Every card rolls a tier from randomness committed before your transaction lands:

Tier	Card	MH/s	Odds
Common	Spud GT 210	10	52%
Uncommon	Miner MX 450	25	26%
Rare	Volt VX 3060	60	13%
Epic	Blaze BZ 4080	150	7%
Legendary	Quantum QX 9090	400	2%
Mythic	Singularity ∞	1,000	fusion only
Forged	???	2,500	fusion only

• One stream, every second, pro-rata by hashrate. Rewards drip over rolling 12-hour windows and the stream pauses when the rig is empty — time never steals from miners.
• The money loop: 70% of every mint, overclock, fusion, rack, and royalty buys $GPU on the open market and streams it straight to miners — plus 30% of our share of $GPU's trading fees on Pons (4% per trade: 1% pool fee + 3% creator tax; the other 70% funds the project treasury).
• The burn: every mint torches 12,500 $GPU from your wallet. Full mint = 125,000,000 burned — 12.5% of everything that will ever exist.
• Climb: overclock (+20%/level, max +100%), fuse two identical cards into the next tier (supply only shrinks), expand your room from 4 to 52 slots.
• Secondary sales: 5% royalty (ERC-2981) on OpenSea and every honoring marketplace, paid to the ownerless RoyaltyRouter — 70% of it streams back to the miners' pot.

The trust model

Piece	Power	Ceiling
Rig	none — no owner	no pause, no parameters, no withdraw
Keeper	buy $GPU with the pot	min-output + balance-delta verified; can't pay itself
RoyaltyRouter	none — no owner at all	hardcoded 70/30, permissionless flush
Shop owner	rotate permit signer, tune burn dial	dial is band-limited at deploy; can't touch cards or the 70%
Mint randomness	committed in the signed permit	reproducible by anyone, riggable by no one

Anti-bot by construction: contracts can't mint and permits expire in 5 minutes. No mint caps, no cooldowns — mint as many as you want, whenever you want.

The site ships its own permit signer as a Vercel function (web/api/permit.ts) — deploy web/ on Vercel with one env var (SIGNER_PK) and the mint is live.

• Core contracts + 39 passing tests
• Pons bonding-curve adapter + Uniswap v3 adapter (v4 adapter lands at graduation)

Not financial advice

Unaudited. Unlaunched. The rig has no owner, the keeper can only buy, and the code is public — but this is a game. Only spend what you are happy to lose.
