CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.
- End-to-End Development: From specification and gas optimization to deployment and verification on
EVM/Solana/Cosmoschains. - Security Audits: Every contract undergoes internal review against common vulnerabilities (reentrancy, overflow) before we recommend third-party audits.
- Upgradeable Architecture: Build with future-proof patterns like
Transparent ProxyorUUPSfor seamless, secure updates. - Integration Ready: Contracts are delivered with comprehensive documentation and integration tests for your front-end team.
We deliver battle-tested code that reduces time-to-audit by 40% and provides a secure foundation for scaling to millions in TVL.

INSTITUTIONAL-GRADE RIGOR
Our Security Audit Methodology
Our multi-layered audit process is engineered to meet the stringent security, compliance, and operational demands of financial institutions and high-value gateways.
01
Comprehensive Threat Modeling
We begin with a systematic analysis of your gateway's architecture to identify and prioritize attack vectors, from frontend UI exploits to consensus-level threats, ensuring no critical vulnerability is overlooked.

Framework
02
Manual Code Review & Static Analysis
Senior auditors conduct line-by-line reviews of smart contracts and backend systems, supplemented by automated static analysis tools (Slither, MythX) to detect subtle logic flaws and gas inefficiencies.

FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
End-to-end blockchain solutions from core protocol design to production deployment.
We architect and build custom blockchain networks and Layer 2 solutions tailored to your specific transaction volume, privacy, and governance needs. Our development process delivers a production-ready mainnet in 8-12 weeks, complete with validators, explorers, and cross-chain bridges.
From a private consortium chain for enterprise data to a high-throughput public L2, we deliver the foundational infrastructure your application requires.
- Core Protocol Design: Custom consensus (
PoA,PoS), token economics, and governance models. - Node & Validator Setup: Deployment of
Geth,Besu, orSubstratenodes with orchestration tools like Kubernetes. - Essential Tooling: Block explorers, wallet integrations, and
Chainlinkoracles for real-world data. - Security & Compliance: Built-in audit trails, role-based access control, and regulatory-ready architecture.
