Collector Crypt

Collector Crypt lets you buy and trade real graded Pokémon cards as tokens on Solana. Each token is backed 1:1 by a physical slab held in an insured vault, and can be redeemed for the physical card at any time.

It brings instant settlement and 24/7 liquidity to graded cards, and is one of the largest sources of tokenized Pokémon inventory. A referral programme is not yet available, so this link is a plain one.
