CORE SERVICES
Blockchain Infrastructure Development
End-to-end development of secure, scalable blockchain infrastructure for Web3 applications.
- Node Operations: Managed
EVM&Solanavalidators, RPC endpoints, and indexers. - Interoperability: Secure bridges and messaging layers using
LayerZero,Wormhole, or Axelar. - Data Infrastructure: High-performance indexers and subgraphs for real-time on-chain data.
- Security First: All infrastructure undergoes rigorous audits and follows
SOC 2-aligned security practices.
Deploy a fully managed, multi-chain infrastructure stack in under 4 weeks, eliminating 6+ months of in-house development and maintenance overhead.

Technical & Commercial Questions
ZK Voting SDK FAQs
Common questions from CTOs and product leads evaluating private voting infrastructure.
For a standard ZK voting system with custom governance logic, the typical timeline is 4-6 weeks. This includes 1 week for requirements & design, 2-3 weeks for core SDK integration and smart contract development, and 1-2 weeks for audit preparation and deployment. We deliver a working prototype for your review by the end of week 2.
