Buy a sealed prism. When it sells out, one draw reveals them all at once, across gems, rarities and timezones. Then each card sells only in its window.

Install MetaMask or Rabby, then add Robinhood Chain in one click.
Connect your wallet, pick a quantity, confirm. The sealed prism is yours until reveal.
Each card is bound to a world timezone with a 4h window, day (11:00-15:00) or night (23:00-03:00). The contract enforces it, so the rule holds on any marketplace. This is the wave: trading rolls around the globe.
You buy a sealed prism. Once all 777 are sold, a 5h countdown starts, then one on-chain draw reveals every card at once: gem, rarity, timezone, and its stats.
On the Marketplace. Built-in market: list anytime, the sale settles only inside your card's window, royalties handled on-chain.
No. The 777 deck is hash-committed before the sale, and the reveal mixes a pre-committed secret with a future block hash that was unknown when locked. Neither the team nor the network can target the outcome.
$PRSM is the utility token. You claim it just by holding a card, once every 24h, inside that card's window, from your Coffre. Rarer cards claim more. Claimed $PRSM is locked (lock-until-spend) · claiming opens right at sold-out, and trading opens later when liquidity is added.
The main sink. Collect one card from each of the 8 timezones, deposit them (each in its window), and craft: the 8 cards are burned and you mint one unique World Prism, plus a $PRSM cost.
