Gem Mint Infinite is the first trading platform for sports cards and memorabilia that lets you verify authenticity and prove ownership without revealing your identity — built on Midnight's zero-knowledge blockchain.
No spam. You'll hear from us when we launch.
When you buy or sell a $5,000 card on eBay or Fanatics, you hand over your name, address, payment info, purchase history, and browsing data. That data is stored, sold, and at risk — forever.
Fanatics and eBay collect your purchases, financial info, contact details, search history, and identifiers — all linked to your real identity. High-value collectors are exposed to fraud, targeted theft, and data breaches with every transaction.
Fake graded slabs, switched cards, counterfeit autographs. Today's authentication relies entirely on trusting a central party. There is no way to cryptographically prove a card's provenance without a platform holding your data.
Zero-knowledge proofs let you prove you own a card, that it's authenticated, and that a transfer happened — without revealing your name, wallet, or any personal data. The card's history lives on-chain. Your identity doesn't.
No middleman holding your cards or your data. Transactions settle on Midnight using ADA — no credit card, no bank account, no paper trail connecting you to your collection.
Submit your PSA, BGS, or SGC graded card. We generate a cryptographic proof of authenticity tied to the card's certification number — permanently recorded on Midnight's blockchain. No name required.
Create a listing visible to buyers. Your identity is never shown — only the card's proof record, grade, and asking price. Buyers can independently verify the card's authenticity before making an offer.
When a sale closes, ownership transfers on-chain with a zero-knowledge proof. The buyer receives verified ownership. The seller receives ADA. No personal data changes hands.
Cardano's privacy-first partner chain, live on mainnet since March 2026. Backed by Google Cloud, MoneyGram, and Worldpay. Uses zero-knowledge cryptography to enable selective data disclosure — prove facts without revealing underlying data.
ZK proofs let anyone verify that a statement is true — "this card is PSA 10 and I own it" — without learning anything else. The math is sound. The privacy is real. This is the same technology used by Ethereum's most advanced scaling solutions.
Payments settle in ADA — one of the most decentralized, peer-reviewed blockchains in existence. Cardano's UTXO model makes transaction verification straightforward and its security model is battle-tested across years of mainnet operation.
Midnight's DUST token powers private transactions and is generated by holding NIGHT — meaning transaction fees don't require purchasing a separate gas token. This makes Gem Mint Infinite economically accessible for everyday collectors, not just whales.
