How It Works
Opening packs on CardChase is simple, transparent, and fair. Here is exactly what happens from the moment you pick a pack to the moment you hold a graded slab.
Pick from Pokemon, One Piece, Basketball, Baseball, or Soccer. Then select one of four price tiers — Starter ($15), Premium ($50), Ultra ($100), or Chase ($250) — each with different card counts and rarity odds.
Complete your purchase through secure Stripe checkout. We support all major credit and debit cards. You get instant confirmation and your pack is ready to open immediately — no waiting.
Watch your cards reveal one by one with rarity-specific visual effects. Every pull is determined by HMAC-SHA256 cryptographic RNG with a pre-committed server seed — provably fair and verifiable after the fact.
Pulled cards are instantly delivered to your personal digital vault. Each card displays its grade, grading company, and live estimated market value. Your collection is organized, searchable, and always accessible.
List any card on the CardChase marketplace with just an 8% seller fee — far below the industry standard. Or request physical delivery to your door and hold the graded slab in your hands. Your cards, your choice.

HMAC-SHA256
RNG Method
Provably fair
Before you open a pack, the server generates a server seed and commits its HMAC-SHA256 hash to the database. This hash is visible to you before you open.
When you click open, a client seed (unique to your session) is combined with the server seed to determine your results. The combination is deterministic \u2014 the same inputs always produce the same outputs.
After the reveal, the server seed is disclosed. You can independently hash it, combine with your client seed, and verify that the results match exactly. If they do not, the pull was tampered with \u2014 but cryptographically, that is not possible without changing the pre-committed hash.
This is the same provably fair standard used by regulated online platforms worldwide.
Pick a game, choose a tier, and see what you pull.
