CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic.
- Security-First Development: Code written in
Solidity 0.8+usingOpenZeppelinlibraries and audited patterns. - Comprehensive Testing: Unit, integration, and fork testing on
HardhatorFoundryto ensure reliability. - Gas Optimization: Every contract is optimized for lower transaction costs and efficient on-chain execution.
- Full Deployment Support: We handle deployment to
EVM-compatible chains (Ethereum, Polygon, Arbitrum) with verified source code.
We don't just write code; we deliver the secure, auditable on-chain logic that powers your product's core value proposition.

ENTERPRISE-GRADE ARCHITECTURE
Core Technical Capabilities
Our stealth vault development is built on a foundation of institutional-grade security, compliance, and performance. We deliver battle-tested solutions that meet the stringent requirements of regulated entities and high-value asset managers.
01
Zero-Knowledge Privacy Layer
Implement privacy-preserving transactions using zk-SNARKs or zk-STARKs to shield asset movements and balances from public view, while maintaining full auditability for authorized parties.

Frequently Asked Questions
Common questions from CTOs and founders about developing secure, compliant, and high-performance private transaction infrastructure.
A production-ready stealth vault with core features (private deposits, shielded transfers, compliance hooks) typically deploys in 3-5 weeks. Complex integrations with existing custody systems or custom regulatory modules can extend this to 6-8 weeks. We follow a phased delivery model with weekly demos.
