Built on SP3ND and Collector Crypt

two rails: one for buying cards with stablecoins anywhere, one for holding and trading them on-chain

Collector Crypt

The venue. PSA-graded cards sit in a vault and trade as tokens in USDC on Solana. This is where slab buys, lists, reprices and sells, where it pays 2% on every sale, and where its holdings are reconciled against the chain every half hour.

live in the loop

SP3ND

The buying rail for the physical world. SP3ND lets an agent shop Amazon and eBay with USDC over x402: no card, no KYC, no country lock. slab uses it to buy graded cards off eBay when they are cheaper there than on the venue, shipped straight to the vault to be tokenised and listed.
