We architect and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis, manual review, and formal verification, before mainnet deployment.

Technical & Commercial Considerations
DePIN Payment Verification: Key Questions
Answers to the most common questions CTOs and founders ask when evaluating a DePIN hardware payment verification node.
Standard deployment for a production-ready DePIN payment verification node takes 2-4 weeks. This includes environment setup, custom rule configuration, integration with your existing payment rails, and a 7-day monitoring period. Complex integrations with legacy systems or custom consensus mechanisms can extend this to 6-8 weeks.
