What Playmint does
Playmint was a Brighton, UK-based Web3 game development studio founded in 2021 to build fully on-chain games that use blockchain as a decentralized computing platform rather than solely for asset ownership. Its portfolio included The Crypt (the world's first fully on-chain co-op multiplayer dungeon game, launched 2021), Downstream (an on-chain autonomous-world game released in summer 2024 where any player can add code to expand the shared game world), Space Shooter (a proof-of-concept demonstrating Playerchains), and Playerchains itself — a proprietary peer-to-peer DAG consensus system enabling trustless multiplayer without a central server. The studio also pioneered client-side proofs, a cryptographic technique for safely offloading computational work from the blockchain. All code was published openly on GitHub, and game state, player actions, and worlds were designed to persist immutably on-chain independent of the studio's operational status.
The company served two primary segments: blockchain gaming enthusiasts who value true player ownership and game permanence, and Web3 game developers attracted to decentralized, open platforms free from centralized publisher constraints. The studio's differentiation rested on architectural novelty — protocol-style games that no single entity owns — rather than conventional monetization mechanics. Playmint raised approximately $4.4 million across two funding rounds (a $3.9M seed led by BITKRAFT Ventures in April 2022 and a $500,000 round led by a16z crypto in March 2024), supported a team of 11-50 employees, and operated without publicly disclosed pricing or revenue. In late 2025, Playmint was acquired by Cartridge, the world's leading on-chain game infrastructure company, bringing its technology, talent, and games into Cartridge's broader platform.
