Introduction

Crystara's blind box collections transform traditional NFT minting into an exciting, game-like experience similar to popular gacha mechanics found in many successful games.

What are Blind Box Collections?​

Blind Box Collections on Crystara are NFT collections where collectors don't know exactly which NFT they'll receive until after the minting process. This creates an element of surprise and excitement, similar to opening a mystery box or pack of collectible cards.

Key Benefits​

For Creators​

  • Increased Engagement - The element of chance creates more excitement around your collection launch
  • Fair Distribution - Rare items are distributed randomly, creating equal opportunities for all collectors
  • Extended Interest - The mystery aspect can extend the lifetime and interest in your collection
  • Flexible Rarity Design - Create custom rarity tiers with precise drop rates

For Collectors​

  • Exciting Experience - The thrill of not knowing what you'll get until the reveal
  • Fair Chance at Rare Items - Everyone has the same probability of minting rare NFTs
  • Community Building - Creates shared experiences of discovery and trading
  • Verifiable Fairness - All randomness is powered by Supra's dVRF, ensuring transparency

How It Works​

  1. Creator Sets Up Collection - Defines NFTs, rarity tiers, and drop rates
  2. Collector Mints a Mystery NFT - Pays the mint price without knowing which specific NFT they'll receive
  3. Randomness Generation - Supra's dVRF generates a verifiable random number
  4. NFT Assignment - The system assigns an NFT based on the random number and predefined probabilities
  5. Reveal - The collector discovers which NFT they received
