FOUNDATION
Custom Blockchain Development
Build secure, scalable blockchain networks tailored to your business logic and performance requirements.
We don't just deploy a chain; we engineer a system designed for your exact transaction volume, finality needs, and governance model.
- Protocol-Level Customization: Modify consensus (
Proof-of-Stake,Proof-of-Authority), block parameters, and fee mechanics. - Full-Stack Tooling: Includes block explorers, RPC endpoints, cross-chain bridges, and wallet integrations.
- Security-First Build: Undergoes formal verification and third-party audits before mainnet launch.
- Ongoing Node Operations: We provide managed validators and infrastructure with 99.9% uptime SLA.

Frequently Asked Questions
Common questions from CTOs and technical founders about building secure, reliable, and scalable on-chain data infrastructure.
For a standard multi-source feed (e.g., price oracle with 3-5 sources), we deliver a production-ready, audited solution in 4-6 weeks. This includes design, development, testing, and a security review. Complex feeds with custom logic or cross-chain capabilities may take 6-10 weeks. We provide a detailed project plan with milestones during the initial scoping call.
