Verifiable randomness · CC-VRF

No trust. Only proof

Every winner is drawn by CC-VRF — Collector Crypt’s verifiable random function on Solana — and recomputable right here in your browser. The treasury and vault are open too.

The math is open

The winner is the boost-weighted entry the CC-VRF output lands on: beta = ECVRF(operatorKey, sha256(memo ‖ blockHash)); roll = beta mod totalWeight. Each entry’s weight = balance × Hold × Charge. The operator key is frozen on-chain, the entry set locks ~16 min before the draw, and the input is then bound to a fresh Solana block hash at draw time — so the result can’t be known in advance, by us or anyone. Every draw commits its proof on-chain, so the check above runs entirely in your browser, and against Collector Crypt’s open tooling too. Nothing to take on faith.

How do I enter?

Hold the token. You need at least 25,000 $GPUMP to be entered in the draw; from there your share of the eligible supply is your base chance, boosted by how long you hold (Hold) and how long you go without winning (Charge). No staking, signup, or tickets.

Where do prizes come from?

Trading fees automatically buy a real PSA, BGS or CGC graded slab via Collector Crypt every hour and rip it live as the prize.

How often is a draw?

Every hour, automatically. The more it trades, the bigger the pulls.

Physical or cash?

At claim the winner takes the slab to their wallet or cashes it out for USDC on the spot via Collector Crypt's buyback. If the winner doesn't claim within 72h, we sell the card and send the USDC, so nobody loses out.
