How Rarefold works

Buy collectible card packs at fixed, discounted prices, or play a 3D claw machine where every paid play wins a card. Payments are in USDC on Solana and are verified on our server before anything is awarded.

Overview

Each purchase reserves a real item from our inventory the moment you start checkout, and holds it for 10 minutes while you pay. Once our server confirms your payment on-chain, the item is assigned to your wallet's account and appears in your collection.

Rarefold is independent. We are not affiliated with, sponsored or endorsed by any trading card publisher, sports league or pack platform, and packs cannot be redeemed anywhere else. Pack wrapper art is original.

Packs

Every pack contains the number of cards shown on its page. When you open a pack, one card is drawn at random from that pack's pool. Every card remaining in the pool has an equal chance, so the odds shown on each pack page are the live counts per rarity — they change as cards are pulled.

Reference prices are comparison figures we set ourselves; they are not live quotes from any other platform. Prices are charged 1:1 in USDC. Nothing here is a promise of resale value or profit.

The Claw

One play costs $5.00 USDC and always awards exactly one card. When your play is authorized, the machine is stocked with 12 capsules in this mix:

• Common6 of 12 capsules · 50.0%
• Rare3 of 12 capsules · 25.0%
• Epic2 of 12 capsules · 16.7%
• Legendary1 of 12 capsules · 8.3%

You have 30 seconds to position the claw (WASD or arrow keys, or the joystick on mobile), then drop it. If all three prongs close around a capsule, it is carried to the chute — there is no hidden slip chance. A capsule that lands in the chute wins a card of that capsule's rarity. If no capsule is delivered, you still receive one card: its rarity is drawn from the capsule mix above, with the listed probabilities.

The grab itself is a real-time physics simulation in your browser. Our server checks that a reported grab is plausible (the capsule was within reach of where the claw dropped) before awarding that rarity; otherwise the guaranteed draw applies. If a tier is out of stock, its capsules are replaced by the lowest in-stock tier before the round starts, and the machine shows the live mix before you pay. A paid play you don't finish is resolved with the guaranteed draw after 10 minutes.

Wallets & payments

Connect Phantom, Solflare or another Solana wallet. You'll sign a short message to prove you own the address — that signature never moves funds. Purchases are a single USDC transfer to our treasury that you approve in your wallet. Network fees are paid in SOL.

Each order has a unique reference key included in its transaction. Our server only accepts a payment when it is confirmed on Solana, signed by your wallet, carries that order's reference, and moves at least the order amount of official USDC (4zMM…ncDU on devnet) into our treasury. A transaction can only ever be used once.

If your browser closes mid-payment, nothing is lost: your order is re-checked by its reference when you return, and we never ask you to pay again for an order that already has a payment in flight.

Your collection

Your collection lives under your wallet menu. Cards are off-chain records in our inventory system tied to your wallet address. They are not NFTs or tokens, and they cannot be withdrawn on-chain. Each card shows whether it is a physical card we hold or a demo record.

Delivery & refunds

Physical cards are stored by us after you win them. Shipping requests are not yet available in this version; when they launch, eligible cards will be shippable to supported regions and shipping costs will be shown before you confirm.

All sales are final once a pack is opened or a claw play is authorized. If you pay and the item you reserved is no longer available — for example, your payment arrived after the hold expired and the pool sold out — the order is marked for a full USDC refund to the paying wallet. Contact support with your transaction link for any issue.

Eligibility

You must be 18 or older (or the age of majority where you live) to buy packs or play. Randomized prize mechanics paid for with money may be restricted in your country, state or region; you are responsible for checking local law before using Rarefold. We may block access from restricted jurisdictions. The operator must complete legal review for each target market before enabling real payments.

Security & fairness

• Prizes are always chosen on the server using a cryptographically secure random source — never in the browser.
• Inventory is reserved atomically, so two buyers can never be assigned the same card.
• Orders are idempotent: retries, reloads and double clicks return the same order and the same result.
• Sessions are bound to a signed wallet message and expire after seven days.

Demo mode

This site is currently running in demo mode. In demo mode, no USDC is charged and all inventory is clearly marked sample data with no physical card behind it. Demo results have no cash or resale value. A throwaway “Demo wallet” is offered so you can try the full flow without installing anything.
