Cardinal

Collectibles raffle marketplace

Pixel8Labs built an on-chain Pokemon card raffle marketplace on Sui where virtual packs are backed by physical cards, powered by a verifiable randomizer.

The Challenge

A collectibles marketplace needed provably fair digital pack openings where each virtual pack is backed by a real, graded card. Users had to trust the randomizer wasn’t rigged.

Our Approach

We built the marketplace for virtual pack openings and rare-item raffles, backed by physical graded cards. Every opening uses a verifiable randomizer so users can confirm fairness independently.
