Non-custodial cryptocurrency exchange ShapeShift has burned hundreds of themed collectible “cards” from the blockchain-based mobile game Spells of Genesis. According to the team, the cards remaining in their possession would be under the control and management of the new autonomous decentralized organization (DAO) and will then be unlocked over limited periods in the next two years.

On-chain data shows that parties such as ShapeShift are included in the on-chain. at least 817 of the digital cards titled “ShapeShift the Wanderer” — originally minted in June 2015. The announcement on Oct. 12, that the exchange was being shut down, came after this news. It is intended to destroy 649 cards to make those in circulation “among the most rare [Spells of Genesis] cards in existence and among the oldest NFTs in existence.” Other parties appear to have burned an additional 168 cards at some point in the past as well, leaving less than 200 cards distributable on-chain.
