CardAuditOS is the neutral verification layer for the trading card market. Verified seller identities. Real transaction records. No more relying on platforms with every incentive to look the other way.
The companies that grade cards also sell cards. The platforms that host transactions also profit from volume. Collectors have no neutral party to turn to.
PSA's own internal audit exposed grade manipulation — cards graded 9, secretly upgraded to 10 after buyback. Anthony Curcio was convicted for forging PSA grades on Pokemon and sports cards. Forged grades are everywhere.
Marketplace reviews are gamed at scale. Fake positive reviews from new accounts, review farms, and incentivized buyers inflate seller ratings. A 4.8-star seller might have zero verified transactions.
Traders on trading platforms get burned by exit scams — sellers collect payment and disappear, or platform operators shut down with customer funds. There is no recourse.
We don't just aggregate reviews. We verify identity, track real transaction outcomes, and make fraud difficult to hide.
Every seller on CardAuditOS passes identity verification before leaving a single review. No anonymous accounts, no burner profiles. You know who you're buying from.
List a card with a PSA 9 grade? We check it against the PSA certification database. Mismatches are flagged and displayed on the seller's profile. Forged grades don't survive here.
We track actual completed transactions, not just star ratings. A seller's full history — successful deals, disputes, and resolution outcomes — is visible before you buy.
Funds are held in escrow until the buyer confirms receipt and grade match. If a card arrives wrong or a seller ghosts, CardAuditOS resolves the dispute — no more burned collectors.
AI monitors for suspicious seller patterns: newly created accounts with high-value inventory, rapid feedback bursts, and escrow red flags. Scammers don't last long on the platform.
Real-time alerts when a seller you're about to buy from has a flagged history. Know before you click pay. Collectors help protect each other on CardAuditOS.
Before buying anywhere — eBay, Whatnot, TikTok Shop, a private Facebook group — search the seller's CardAuditOS profile. See their verified identity, transaction history, and any dispute records.
For high-value sales, use CardAuditOS escrow. Your funds are held securely while the seller ships. On receipt, the buyer verifies the card matches the listed grade and condition.
After every verified transaction, both buyer and seller can leave reviews. These reviews are linked to real, verified transactions — not anonymous feedback farms. History you can trust.
PSA processed 19 million cards in 2025. Each one had a buyer who needed to trust the seller. CardAuditOS is building the verification layer that makes that trust possible — neutral, independent, and built for the long term.
