Biometric-Binding Decentralized Identity SDK

An SDK that cryptographically binds a user's DID to locally stored biometric data, enabling high-assurance, user-friendly authentication without centralized biometric databases.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production from day one.

We architect and deploy custom smart contracts on EVM and Solana that are secure by design. Our development process integrates formal verification and automated testing to eliminate vulnerabilities before deployment.

Deliver a production-ready contract suite in 2-4 weeks, backed by a 99.9% uptime SLA and comprehensive audit reports.

  • Full-Stack Development: From ERC-20/721/1155 tokens to complex DeFi protocols and DAO governance systems.
  • Security-First Process: Built with OpenZeppelin standards, reviewed via Slither/MythX, and prepared for third-party audits.
  • Gas Optimization: Expert tuning to reduce deployment and transaction costs by 20-40%.
  • Post-Deployment Support: Includes monitoring, upgradeability patterns, and incident response.

Our Delivery Methodology

We deliver enterprise-grade biometric identity SDKs through a structured, milestone-driven process that ensures security, compliance, and rapid integration.

01

Architecture & Protocol Design

We design your SDK's core architecture, selecting optimal zero-knowledge proof circuits (e.g., Circom, Noir) and on-chain verification logic (EIP-4337, ERC-4337) for maximum security and gas efficiency.

Frequently Asked Questions

Common questions from CTOs and product leads evaluating our identity SDK for their FinTech or Web3 applications.

A standard integration takes 2-4 weeks from kickoff to production. This includes initial scoping, SDK integration into your mobile/web app, biometric binding configuration (Face ID/Touch ID/Android Biometric), and a security review. Complex multi-chain deployments or custom credential schemas may extend this to 6-8 weeks. We provide a detailed project plan in the first week.
