Vara.eth
Build high-performance applications on Ethereum with parallel execution and reverse gas.
Welcome to Vara.eth
Vara.eth brings high-performance computation directly to Ethereum. Build apps that were previously impossible on-chain — with parallel execution, 2 GB memory per program, and users who never pay gas.
Where do you want to start?
Build with an AI agent
Modern development runs on AI agents. Whether you're shipping a production dApp or prototyping an idea, tell Claude Code, Codex, or Cursor what you need — Vara.eth Agent Skills walk the agent through Sails contracts, ethexe deployment, ABI, and frontend with verified, documentation-backed patterns. Available right now.

Vara.eth is proven live on Ethereum — start building today. The TestNet and MainNet campaigns ran the full stack end to end. One of Us drew 931 members — one click each, no gas paid by users; Robo Miner put AI agents into a live on-chain arena. Both are open source and work as reference applications.
Those campaigns are complete, and the Gear-operated public endpoints (Ethereum RPC, Beacon, and the Vara.eth validator network) are no longer served. Everything else is unchanged — the Router and wVARA contracts stay deployed and verifiable on Ethereum Mainnet and Hoodi, and the whole stack is open source. Point ethexe at any Ethereum RPC provider, or run your own node, and reproduce the entire flow. You can also build with Agent Skills.
