CORE INFRASTRUCTURE
Smart Contract Development
Secure, gas-optimized smart contracts built for production by Web3-native engineers.
- Production-Ready Code: Contracts are written in
Solidity 0.8+,Rust, orVyperwith comprehensive testing, documentation, and gas optimization. - Security & Audits: Every contract undergoes formal verification and is prepared for third-party audits from firms like CertiK or Quantstamp.
- Full Lifecycle Support: From ideation and architecture to deployment, monitoring, and upgrade management via transparent proxy patterns.
We deliver contracts that are not just functional but are engineered for long-term security, scalability, and maintainability, reducing your technical debt and audit cycle time.

Frequently Asked Questions
Get clear answers on how we secure your protocol's financial logic while protecting sensitive data.
A comprehensive audit for a standard lending or credit protocol takes 2-3 weeks from kickoff to final report. This includes a 5-day initial review, 10-12 days of deep analysis by senior engineers, and 3 days for report generation and client review. Complex protocols with novel mechanisms may extend to 4 weeks.
