The upstream inventory
Collector Crypt is the upstream Solana marketplace and physical card custody layer used by Rard. Live catalog data, pack stock, published prices, odds and slab information originate there.
The slab remains in professional custody until a valid redemption is completed.
Gacha rules
- Live terms.Price, inventory and rarity odds are refreshed from the upstream source. If live terms move before funding, the action pauses.
- Published price.The displayed pack price combines the Collector Crypt pack price and the Rard service margin.
- Exact funding.The authorization adds a bridge safety buffer of $0.25 plus 0.1% of the upstream pack price. The exact total is shown before signing.
- One terminal result.Every funded reveal resolves as a card or a refund. A failed reveal does not become an open-ended platform balance.
- Random outcome.The card is selected according to the live rarity distribution. Expected value is descriptive, never a guaranteed return.
Market rules
Funded offer
Offers must be below the current ask. Authorization equals the offer plus the displayed bridge buffer. Funds remain accounted for while the offer is open.
Direct purchase
A member resale authorizes exactly the asking price. No bridge buffer is added to a member-to-member purchase.
One slab, one on-chain twin
A settled card is represented 1:1 by a MirrorCard on Robinhood Chain. The token is the on-chain receipt for the custodied slab; it is not a second copy of the card. The holder may keep it, list it through supported resale paths, use an available buyback, or begin physical redemption from Vault.

Vault, offers and recovery
- Your cards.Vault reads current MirrorCard ownership from Robinhood Chain and combines it with Fletcher metadata, value, buyback and listing state.
- Your listings.A holder may create or cancel a member resale. The first listing or buyback requires approval for the configured settlement mover.
- Your offers.An open funded offer may be cancelled from Vault; Fletcher then handles the refund path. Seller-side manual acceptance is not exposed by the upstream service, so fills appear automatically when upstream settles them.
- Buyback and redemption.Eligible cards can use the live Collector Crypt buyback quote or request physical shipment after the exact withdrawal and shipping fees are shown.
- Recovery queue.Every started saga is recorded in this browser. If a page closes mid-settlement, Activity can recheck the upstream state without creating a second payment.
Risk, pricing and fairness
Collectibles are volatile and illiquid. Rarity, insured value, expected value and historical interest do not promise resale value or profit. Network fees, upstream availability and cross-chain settlement conditions can change between viewing and signing. If the verified terms no longer match, the action should stop rather than silently charge a different amount.
