Mystery Packs

Three-prize pack opening that settles NFTs, tokens, and physical goods

Mystery Packs opening screen showing three revealed prizes

Overview

A white-label pack-opening product where a single purchase — in SPL tokens or SOL — returns three prizes drawn from one weighted table mixing NFTs, fungible tokens, and real merchandise. The hard part is that one pull can produce three different settlement paths, so the reveal and the fulfilment have to stay in step. Operators run their own branded instance and edit prize tables and theming without touching code.

What was built

  • Weighted prize tables spanning NFT, token, and physical rewards in one draw
  • Dual payment rails — SPL token or SOL — resolving to the same pack pipeline
  • Reveal sequence synchronised to settled results, with fulfilment for physical wins
  • Operator-managed prize tables and theming across independently deployed tenants
