What Is Caggy? The Graded Card Aggregator Explained

· 4 min read · By Caggy Team

If you collect graded cards — Pokemon, basketball, baseball, or Yu-Gi-Oh — you know the pain. Cards are scattered across multiple blockchain marketplaces. Comparing prices means opening four tabs, remembering which wallet holds what, and hoping you don’t miss a deal.

Caggy fixes that. We aggregate graded card listings from Courtyard, Beezie, Phygitals, and CollectorCrypt into a single, searchable marketplace.

The Problem: Fragmented Marketplaces

Graded cards (PSA, CGC, BGS) are increasingly tokenized on blockchain platforms. Each platform has its own inventory, pricing, and user experience:

  • Courtyard — Polygon-based, strong PSA inventory
  • Beezie — Multi-chain (Flow + Base), growing marketplace
  • Phygitals — Solana-based, diverse graders
  • CollectorCrypt — Solana-based, emerging platform

As a collector, you’d need to check all four platforms to find the best price on a specific card. That’s tedious and error-prone. (For a detailed look at how these platforms differ, see our Courtyard vs CollectorCrypt vs Beezie comparison.)

How Caggy Works

Caggy syncs data from all four platforms and normalizes it into a unified view:

  1. Portfolio View — Connect your wallets and see all your graded cards in one place, regardless of which marketplace they’re on
  2. Marketplace View — Browse 300,000+ graded cards, compare prices across platforms, and find the best deals
  3. Card Identity System — Our deduplication engine recognizes the same card across platforms, so you can see all listings for a specific cert number side by side

What Makes Caggy Different

Unlike individual marketplaces, Caggy doesn’t sell cards. We’re a discovery and comparison tool:

  • Cross-platform search — Find any graded card across all four marketplaces
  • Price comparison — See the same card listed at different prices on different platforms
  • Multi-wallet support — Connect EVM and Solana wallets, see everything in one portfolio
  • Grader filtering — Filter by PSA, CGC, or BGS across all platforms
