Mobile Privacy-Focused Payment Protocols

We implement privacy-preserving payment features in your mobile app using zero-knowledge proofs and confidential assets. Protect transaction details while maintaining compliance and auditability.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

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.

  • Full-Stack Development: From ERC-20 tokens and ERC-721 NFTs 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.

PROVEN PROCESS

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.

01

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.

CORE SERVICES

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 like ERC-4626 for vaults or ERC-6900 for 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.
