We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process is built on security-first principles with formal verification and multi-audit cycles, ensuring your core logic is robust against exploits.
Mobile Privacy-Focused Payment Protocols
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Full-Stack Development: From
ERC-20tokens andERC-721NFTs to complex DeFi primitives like AMMs and lending pools. - Security & Audits: Rigorous testing with tools like Slither and MythX, followed by audits from top firms.
- Gas Optimization: Code reviewed for efficiency, reducing user transaction costs by 20-40% on average.
- Mainnet Deployment: End-to-end support from testnets (
Goerli,Sepolia) to mainnet launch on Ethereum, Polygon, or Base.
We deliver audited, production-grade contracts in 2-4 weeks, turning your specification into live, secure code.

Our Delivery Methodology
We deliver production-ready mobile payment protocols through a structured, security-first approach that reduces your time-to-market and technical risk.
Privacy Architecture Design
We architect your protocol using zero-knowledge proofs (ZKPs) and secure multi-party computation (sMPC) to ensure transaction privacy without sacrificing compliance. Our designs are based on proven patterns from Zcash and Monero ecosystems.
Secure Mobile SDK Development
We build lightweight, platform-native SDKs (iOS/Android) with hardware-backed key storage (Keychain/Keystore) and biometric authentication. Includes comprehensive documentation and integration guides.
Smart Contract & Backend Integration
Deploy audited smart contracts for settlement and custody on EVM or Solana, paired with a resilient backend orchestrator for off-chain computation and fraud detection.
Penetration Testing & Audit
Every component undergoes internal review and external audit by firms like Trail of Bits or Quantstamp before mainnet deployment. We provide a verifiable audit report.
Staged Deployment & Go-Live
We manage a phased rollout from testnet to mainnet, including load testing, monitoring dashboard setup, and team training to ensure a smooth production launch.
Ongoing Protocol Upgrades
We provide maintenance and upgrade services for protocol improvements, vulnerability patches, and integration with new privacy-preserving technologies like zk-SNARKs/STARKs.
Custom Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and compliance requirements.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles using Solidity 0.8+ and OpenZeppelin libraries, with a focus on gas optimization and upgradability patterns like EIP-2535 Diamonds.
Deliver a secure, auditable, and maintainable codebase that reduces risk and accelerates your go-to-market timeline.
- Comprehensive Audit Preparation: We structure code for seamless review by top firms like ConsenSys Diligence or Trail of Bits, significantly reducing remediation cycles.
- Protocol-Specific Expertise: Development for
ERC-20,ERC-721,ERC-1155, and custom standards likeERC-4626for vaults orERC-6900for modular smart accounts. - Gas Optimization: We achieve 20-40% lower transaction costs through efficient storage patterns and assembly-level optimizations where critical.
Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building private mobile payment solutions.
Standard deployments take 6-10 weeks from kickoff to mainnet launch. This includes 2 weeks for architecture design, 3-4 weeks for core smart contract development, 2 weeks for mobile SDK integration, and 1-2 weeks for security audits and final deployment. Complex features like multi-chain support or custom zero-knowledge circuits can extend the timeline, which we scope and estimate upfront.
