overview
CORE ENGINEERING
Custom Smart Contract Development
Secure, gas-optimized smart contracts built for your specific business logic and audited for production.
- From Specification to Mainnet: We handle the full lifecycle—requirements, architecture, development, testing, and deployment—delivering production-ready code.
- Built on Proven Standards: Contracts are developed in
Solidity 0.8+orRust (Solana), leveraging battle-tested libraries likeOpenZeppelin. - Security is Non-Negotiable: Every contract undergoes rigorous internal review and is prepared for formal audits by leading firms like
CertiKorQuantstamp.
We deliver contracts that are not just functional, but are engineered for long-term security, upgradeability, and scalability.
Typical deliverables include custom ERC-20/721/1155 tokens, staking pools, vesting schedules, multi-signature wallets, and bespoke DeFi primitives, with a standard project timeline of 3-6 weeks from kickoff to audit-ready code.

STEALTH STATE MANAGEMENT
Core Capabilities We Deliver
We architect and implement secure, scalable systems that protect sensitive on-chain data while maintaining full composability and auditability for your dApp.
04
State Access Control & Key Management
Develop granular, role-based permission systems for state access, paired with enterprise-grade key management solutions for secure decryption workflows.
05
Audit-Compliant Privacy
Engineer systems with selective disclosure mechanisms, allowing authorized auditors to verify state integrity and compliance without exposing user data.
06
Cross-Chain Stealth State
Enable confidential data and assets to move securely across EVM and non-EVM chains via custom bridge contracts with end-to-end encryption.

PROVEN PROCESS
Our Implementation Methodology
We deliver production-ready stealth state management through a structured, security-first development lifecycle designed for rapid, reliable deployment.
01
Architecture & Threat Modeling
We design your system's privacy architecture using proven patterns like zk-SNARKs, confidential state channels, and secure multi-party computation. This phase identifies attack vectors and defines data flow to ensure confidentiality from day one.

Threat Model Coverage
02
Secure Contract Development
Implementation in Solidity/Vyper using OpenZeppelin libraries and custom privacy-preserving logic. We enforce gas optimization, reentrancy guards, and access control specific to managing hidden state transitions.

03
Rigorous Security Audits
Every contract undergoes multi-layered review: automated analysis (Slither, MythX), internal peer review, and a final audit by a top-tier third-party firm like Trail of Bits or Quantstamp before mainnet deployment.

Stealth Contract State Management
Frequently Asked Questions
Get clear answers on how we deliver secure, scalable, and private state management for your on-chain applications.
A standard implementation for a new protocol takes 3-6 weeks, from initial design to mainnet deployment. This includes the stealth contract system, integration with your existing logic, and a full security audit. For integrating stealth state into an existing, complex protocol, timelines are scoped individually, typically ranging from 4-8 weeks. We provide a detailed project plan within the first week of engagement.
