What is ChainCraft?
ChainCraft is an AI-powered platform that lets anyone create, play, and own multiplayer games through conversation. You describe a game idea in chat, our AI engine generates a fully playable multiplayer game, and it gets minted as an NFT on Arbitrum. No coding required.
Our philosophy: Dream. Play. Earn.
What We Built
Over 9 months on a $300/month burn rate, a core team of 3 shipped:
AI Game Engine We significantly increased the deterministic execution of games, in some cases approaching fully deterministic. AI generates a set of artifacts once per game version, and those artifacts are then processed (often deterministically) for each play session.
This preserves the same cost benefits, while also delivering more reliable and consistent outcomes once artifacts are successfully created. We additionally validate artifacts to catch gameplay errors before sessions are launched.
Live Multiplayer Platform Conversational game builder, multiplayer gameplay for up to 6 players, real-time chat, game explorer, NFT minting, and a featured games system. All live in a controlled beta at play.chaincraft.games.
Three Diamond Pattern Smart Contracts on Arbitrum
-
CCGR (Game Registry): Games published as ERC-721 NFTs with UUID linking
-
CCTD (Token Duels): PvP skill-based wagering with automated payouts
-
CCGA (Game Assets): Cross-game item NFTs with unique URIs
Contracts repo: github.com/chaincraftgames/chaincraft-contracts
Token Duels Our revenue engine. Smart contracts for skill-based wagering where winners earn, creators earn, and referrers earn. Currently on testnet, targeting Arbitrum One mainnet.
ETH Denver & Hackathon Results
ChainCraft had a breakout moment at ETH Denver 2026:
-
Won the Etherspace Track & Top 10 Finalist at ETH Denver 2026 BUIDL Hackathon (Devfolio) — out of 180+ submissions -
Pitched live on stage and on livestream at ETH Denver 2026, driving +500% user growth organically -
Accepted to Arbitrum Founder House NYC for intensive mentorship with Arbitrum’s team
Platform Metrics
| Metric | Value |
|---|---|
| Active Users (30 days) | 62 (+500% during ETH Denver) |
| Wallet Connections | 178 |
| Games Created | 75 |
| Games Published | 17 |
| Total Game Sessions | 734 |
| Multiplayer Sessions | 404 (55%) |
| RPC Requests | 2,810 |
ChainCraft is in controlled beta. We have not pursued paid marketing or growth campaigns. Game building is token-gated to Data Drifter NFT holders while we improve the builder, but all published games are publicly playable by anyone. The ETH Denver growth was entirely organic.
Honest Challenges
Our game publish rate is 22.7% (17/75), and generation reliability is our biggest challenge heading into the next phase.
Context matters here: the majority of our games were built by our own team deliberately stress-testing edge cases — up to 6-player multiplayer, AI narrators, in-game item creation, and other mechanics we wanted proven before a broader rollout. Builders who understand what works well with our platform today see meaningfully better results.
Our architecture review confirmed the engine is “fundamentally sound” and identified the root causes: instruction extraction is the most failure-prone step, with common failures including deadlocked initial states, missing terminal flags, and semantic mismatches where artifacts are syntactically valid but produce broken gameplay. We have a clear technical roadmap including cross-artifact validation, constrained retries, and structured spec summaries projected to reduce failures by ~60%.
We’re not rushing to public launch before these foundations are solid. This is hard, frontier AI work and we know exactly what needs fixing. We’re fixing it.
What’s Next
We have a clear sequence before public launch:
-
Game Builder Reliability (highest priority): One-shot error recovery, cross-artifact validation, “Chainy” AI sim assistant for debugging, templates for proven game patterns, and better error communication
-
Token Duels on Arbitrum One Mainnet: Token Duels is live on Arbitrum testnet and targeting Arbitrum One mainnet for public launch
-
In-Game Image Generation & End-Game Summary Cards: Social sharing mechanic for organic discovery
-
Referral System & Creator/Referrer Rewards: The flywheel that connects user acquisition to revenue
-
AI Credit Purchase System: Sustainable model for covering AI costs at scale
