Business Outcomes: Why Privacy-Enhanced Accounts Matter
Privacy is a competitive advantage. Our smart account designs deliver measurable business value by protecting user data while enabling new revenue models and reducing compliance risk.
01
Regulatory Compliance by Design
Architected for GDPR, CCPA, and MiCA compliance. Our privacy-preserving designs enable selective disclosure and data minimization, reducing legal overhead and audit costs by default.

PROVEN METHODOLOGY
Our Delivery Process: From Architecture to Audit
A structured, security-first approach to delivering production-ready, privacy-focused smart accounts. We provide clear milestones, transparent communication, and verifiable security guarantees at every stage.
01
1. Architecture & Threat Modeling
We define your smart account's security perimeter, data flow, and privacy requirements. This includes identifying attack vectors, specifying zero-knowledge proof circuits, and selecting optimal privacy primitives (e.g., Semaphore, zk-SNARKs).

2. Implementation & Gas Optimization
Development of modular smart account logic using Solidity 0.8+ and OpenZeppelin libraries. We implement privacy features like stealth addresses and confidential transactions, with a focus on gas-efficient circuit design and batch operations.

3. Internal Security Review
Rigorous pre-audit testing including static analysis (Slither), fuzzing (Echidna), and manual code review against the OWASP Top 10 for Web3. We fix all critical and high-severity issues before external audit.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our process delivers audit-ready code in 2-4 weeks, built on battle-tested standards like OpenZeppelin and SPL.
- Security-First Development: Full test coverage, formal verification, and integration with
Slither/MythX. - Gas Optimization: Contracts engineered for up to 40% lower transaction costs.
- Compliance Ready: Built-in support for
ERC-20,ERC-721, and custom regulatory hooks.
We don't just write code; we deliver verifiable, maintainable systems that form the foundation of your protocol.

Frequently Asked Questions on Private Smart Account Design
Get clear answers on our process, security, and outcomes for implementing privacy-first smart accounts for your protocol.
Our process follows a structured 4-phase approach: Discovery & Architecture (1 week), Core Development & Testing (2-3 weeks), Security Audit & Refinement (1-2 weeks), and Deployment & Handoff (1 week). A standard implementation for a custom ERC-4337 account with privacy features like stealth addresses and confidential transactions typically takes 4-6 weeks from kickoff to mainnet deployment.
