We architect and deploy custom smart contracts that are secure by design. Every line of code is written in Solidity 0.8+ using battle-tested patterns from OpenZeppelin and undergoes rigorous internal review before deployment.
Non-Custodial Privacy Wallet Development
Smart Contract Development
Secure, production-ready smart contracts built by Web3 veterans.
- Full Audit Support: We prepare your code for leading security firms like
CertiKandQuantstamp. - Gas Optimization: We write for efficiency, targeting up to 40% lower transaction costs.
- Multi-Chain Ready: Deployments on
EVMchains (Ethereum, Polygon, Arbitrum) andSolanawithSealevel. - Comprehensive Testing: Unit, integration, and scenario testing with
HardhatorFoundry.
From token standards (
ERC-20,ERC-721,ERC-1155) to complex DeFi primitives, we deliver contracts you can stake your business on.

Our Development Process
A proven, end-to-end framework designed for CTOs who need secure, compliant, and scalable privacy wallet solutions delivered on time and on budget.
Discovery & Architecture Design
We start with a deep technical dive to define your wallet's core privacy model (ZK-SNARKs, stealth addresses, coin mixing), token standards (ERC-20, ERC-721), and multi-chain strategy. This phase establishes the technical blueprint and project roadmap.
Core Wallet & Smart Contract Development
Our engineers build the non-custodial wallet core using industry-standard libraries (ethers.js/web3.js) and develop the supporting smart contracts for privacy features. All contracts follow OpenZeppelin patterns and are optimized for gas efficiency.
Security Audits & Penetration Testing
Every line of code undergoes rigorous internal review followed by external audits from our partner security firms. We simulate real-world attack vectors to ensure fund security and privacy guarantees are mathematically sound before mainnet deployment.
UI/UX Integration & Beta Testing
We integrate the wallet engine into your chosen frontend (React Native, Flutter, Web) with a focus on intuitive privacy controls. A closed beta with real users on testnets validates functionality, user flows, and performance under load.
Mainnet Deployment & Monitoring
We manage the secure deployment to mainnet (Ethereum, Polygon, Arbitrum, etc.) and establish 24/7 monitoring for transaction success rates, node health, and anomaly detection. You receive full documentation and handover.
Ongoing Support & Upgrades
Your wallet evolves with the ecosystem. We provide ongoing maintenance, implement upgrades for new privacy protocols (e.g., EIPs), and offer scalability consulting to support your growing user base and asset portfolio.
Smart Contract Development

We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.
- Proven Frameworks: Built with
Solidity 0.8+,Hardhat, and audited libraries likeOpenZeppelin. - Deliverables: Complete contract suite, deployment scripts, and comprehensive technical documentation.
- Key Outcome: Go from spec to mainnet in as little as 4-6 weeks with enterprise-grade security.
We don't just write code; we deliver the foundational logic your entire business runs on, with 99.9% uptime SLAs and post-deployment support.
Frequently Asked Questions
Get clear answers about our process, timelines, security, and support for building your custom privacy-first wallet.
For a core non-custodial wallet with privacy features (e.g., stealth addresses, transaction mixing), we deliver an MVP in 4-6 weeks. A full-featured, production-ready wallet with custom UI/UX, multi-chain support, and advanced privacy protocols typically takes 8-12 weeks. We use agile sprints with weekly demos to ensure alignment and accelerate delivery.
