BUILDING ON STARKNET
Core Technical Capabilities We Deliver
We deliver production-ready, secure, and scalable private voting applications on StarkNet. Our Cairo expertise ensures your dApp meets enterprise-grade security and performance standards from day one.
02
Gas-Optimized Cairo Smart Contracts
Our contracts are built with Cairo 1.0+ and follow OpenZeppelin security patterns. We specialize in gas optimization for StarkNet's L2, reducing your transaction costs by up to 90% compared to L1 execution.
03
End-to-End Audit & Security
Every component—from circuits to frontend—undergoes rigorous internal review and formal verification. We provide a comprehensive audit report, ensuring your dApp is resilient against common and novel attack vectors.
04
Custom Governance & Voting Logic
Tailor voting mechanisms (e.g., quadratic voting, token-weighted, snapshot) to your DAO's needs. We implement proposal lifecycle management, delegation, and result verification as Cairo-native modules.
05
High-Throughput Result Aggregation
Our systems handle thousands of votes per second with sub-second finality on StarkNet. We implement efficient Merkle tree structures for verifiable tallying without compromising privacy.
06
Seamless Frontend Integration
We deliver a fully integrated React/Next.js frontend with StarkNet.js/ArgentX/ArgentX/Braavos wallet connectivity. Includes real-time vote tracking, proof generation UI, and admin dashboards.
