ChainCraft lets anyone build multiplayer games by talking to AI, own them onchain, and earn from them. No coding, no crypto knowledge needed. Wallets are created invisibly through ThirdWeb.
Judges asked to see real engine output. The demo video answers: one continuous session, a complete multiplayer game designed, played, tokenized, and minted onchain in under 30 minutes.
Built during this buildathon:
Sim Assistant: AI agent that diagnoses and repairs game logic mid-session.
Coherence checker catching artifact inconsistencies before simulation.
Deterministic mechanics codegen: TypeScript game logic written once, compiler validated, runs for a fraction of a cent instead of dollars per session.
Onchain item minting via our ERC721 Game Asset contract on Arbitrum Sepolia.
The pipeline is multi-agent end to end: design agent, codegen agent, compiler validation, autonomous repair. That's our Best Agentic case.
Every game ships with an economy: item sales, packs, creator passes, royalties on every resale. Creators keep 95% on item sales. Next: our first full TCG.
During the buildathon we shipped Sim Assistant into the live builder: an AI agent that diagnoses game logic mid-session, escalates repairs to an autonomous repair agent, and restarts the sim with fixes applied. We hardened generation status, timeout, and repair-failure handling, then proved the stack end to end: a complete multiplayer game built, played, tokenized, and minted onchain in under 30 minutes, in one continuous session. Made contact with the first of a list of TCG streamers for collaboration. Sponsor tech: Alchemy Node + Transfers APIs extract our mint and holder data across the ChainCraft diamonds on Arbitrum Sepolia; Dune hosts our public dashboard of that onchain activity: https://dune.com/chaincraft/chaincraft-onchain-activity These are all foundational and just the start as we utilize these platforms more over time.
