Blockchain Cuties
One of the earliest blockchain games, across 5 chains.
#1 Ethereum game on DappRadar (2019)
Context
A collectible breeding and adventure game, launched in four months — before the ERC-721 NFT standard was finalized.
What I did
- First game with cross-chain assets: I architected the multi-chain system — Ethereum, EOS, TRON, NEO and Polygon; after I left, the same design took it to 7.
- Characters and breeding in smart contracts; items and battles on the server, which issues one-time signatures that contracts verify; contract → database sync on own nodes.
- Seasons, crafting with item burning to fight inflation, land presale; governance token contracts and IDO in 2021.
- Custom multi-wallet connector years before RainbowKit; autoscaling infrastructure and card payments.
- Hired and trained the team, ran code audits and planning.
