Introduction

SlabFi is a protocol for tokenizing graded collectible cards. Using AI vision models, anyone can scan a physical card with their phone, receive a predicted grade, and mint a vault NFT that represents that scan onchain.

The goal is straightforward: take an illiquid offline asset class — graded collectibles — and bring it into a programmable, composable environment where price discovery, ownership, and transfer can happen in seconds instead of weeks.

The problem

The graded collectibles market is enormous and growing — Pokémon cards, sports cards, Magic: The Gathering, Yu-Gi-Oh!, and vintage cardboard move billions of dollars annually. But the actual experience of participating in it remains slow, opaque, and inefficient.

• Grading is slow. Sending a card to PSA can take weeks to months for a final grade.
• Liquidity is poor. Once graded, cards sit in safe deposit boxes. Selling means consigning to auction houses or finding buyers manually.
• Price discovery is fragmented. Pop reports, eBay solds, and dealer lists all live in separate places.
• Authentication is centralized. A handful of grading companies control trust in the entire market.

The solution

SlabFi addresses these inefficiencies with three core components:

1. AI grading — Vision models that analyze condition, centering, edges, and surface in seconds.
2. Vault NFTs — Onchain records of physical graded card scans.
3. Programmable ownership — Trade, browse, and reference cards in any onchain context.

How it works

The protocol flow is intentionally simple. Three steps, fully self-serve.

AI grading

SlabFi's grading model predicts the likely outcome of professional grading from visual analysis. It operates on four signals:

• Centering — Symmetry of the printed image within the card border, measured against industry-standard tolerances.
• Corners — Sharpness and integrity of the four card corners.
• Edges — Whitening, dings, and wear along the card edges.
• Surface — Print lines, scratches, holo damage, and overall finish.

Confidence scoring

Each grade prediction is accompanied by a confidence score (0–100%). This represents the model's certainty based on image quality, card recognizability, and similarity to its training distribution. Low confidence scores indicate that a card warrants closer inspection or professional grading before high-value decisions are made.

What the AI sees vs. what it doesn't

The model analyzes what is visible in the photograph. It cannot detect:

• Counterfeit cards that look authentic in photos
• Defects hidden from the camera angle
• Trimmed or altered cards (in many cases)
• Cards in non-standard lighting or with reflections that obscure detail

Tokenized vaults

A SlabFi Vault is an ERC-721 NFT minted on Robinhood Chain. It represents a single graded card scan event and contains all metadata necessary to reference that scan onchain.

Vault metadata structure

What a Vault is and isn't

What it is: A verifiable onchain record of a card scan, with structured metadata and an immutable cert number.

What it isn't: A claim on the physical card itself. Vault NFTs are independent of physical card custody. The owner of a Vault NFT does not have an automatic right to the underlying card — that remains with whoever physically holds it.

Architecture

SlabFi has four high-level components:

$SLAB

$SLAB is the native token associated with the SlabFi ecosystem. It is native to Robinhood Chain — a standard ERC-20 with locked liquidity.

Disclaimer

$SLAB is a memecoin. It has no inherent utility and no expectation of profit. Holders should not anticipate dividends, distributions, governance rights, or claims on the SlabFi protocol's revenue or assets.

AI grading is a predictive tool. Predictions may be inaccurate and should not be used as the sole basis for high-value purchasing, selling, or trading decisions involving physical collectibles.

SlabFi Vault NFTs represent a record of a card scan event. They do not constitute legal ownership of, or claim to, any underlying physical card.

Cryptocurrency is volatile and risky. Only participate with amounts you can afford to lose. Regulations vary by jurisdiction — consult local laws before using the protocol.
