Authentication infrastructure for graded collectibles
Make a graded trading card
impossible to fake.
A cert lookup only proves a serial exists — it can't prove the card inside wasn't swapped, or the label reprinted on a desktop printer. TrueSlab binds every slab to a tamper-evident seal and a computer-vision fingerprint of the card itself, then ledgers every transfer. Scan it, trust it.
26.8M cards graded in 2025. Re-holdering and reprinted labels are the fraud — the fingerprint kills it.

How it works
Four layers. One verdict.
The seal and chip are commodity hardware we source. The moat is the software: a fingerprint of the card itself, an immutable ledger, and a verdict anyone can read.
Slab binding
An identity the case can't shed.
An off-the-shelf crypto NFC chip + QR is bound to the cert — embedded at grading, or added as a tamper-evident seal on existing slabs. Break the seal, void the cert. Sourced, not invented: the chip is commodity.

Card fingerprint
The part you can't forge.
Computer vision captures the card's DNA — centering, corner geometry, print-dot pattern, surface. Swap a cheap card into a real high-grade case and the fingerprint won't match. The card is the key, not the label. This is the moat.

Provenance ledger
A Carfax for every slab.
Immutable history: grade, serial, high-res cert images, and every ownership transfer — queryable by anyone. The chain a lender or vault underwrites against.

Where we sit
Everyone can look a card up. No one binds the card to the slab.
Today's tools confirm a serial exists in a database. None proves the physical card inside wasn't swapped or the label reprinted — and none works neutrally across every grader.

The moat
The card is the key, not the label.
Our computer-vision fingerprint re-identifies the exact card and rejects swaps — the gap a grader's cert lookup can't close. In a v0 proof, same-card captures scored cleanly above swap attempts with zero misclassifications. No training data, no hardware.
