Core Technical Capabilities
Our engineering team delivers production-ready biometric security for blockchain cards, combining hardware-level security with smart contract logic for enterprise-grade applications.
Secure Element Integration
Direct integration with certified Secure Element (SE) and Trusted Execution Environment (TEE) chips (e.g., Infineon, NXP). We handle the low-level communication protocols to enable on-card private key generation and transaction signing, eliminating exposure to host systems.
Smart Contract Wallets & Session Keys
Build Account Abstraction (ERC-4337) compliant smart contract wallets with integrated biometric authentication. Implement session keys for gasless transactions and programmable spending limits, controlled by fingerprint or facial recognition.
Cross-Chain Transaction Orchestration
Biometrically-signed transactions that work seamlessly across EVM, Solana, and other L1/L2 networks. Our relayers and messaging layers ensure atomic composability, allowing a single card gesture to trigger multi-chain operations.
Compliance & Audit-Ready Code
All integration code and smart contracts are developed with security-first principles, undergo formal verification where applicable, and are prepared for third-party audits (e.g., Trail of Bits, Quantstamp). Includes comprehensive documentation for regulatory reviews.
Real-Time Fraud Detection Engine
Embedded machine learning models analyze transaction patterns and biometric signal data in real-time to flag anomalous behavior. Triggers smart contract pausing or step-up authentication without degrading user experience.
Scalable Issuance & Lifecycle Management
Full-stack platform for managing the entire card lifecycle—from personalized applet provisioning and secure key injection at manufacture to remote updates and revocation via blockchain commands.
Business Outcomes for Your Card Program
Our biometric security integration delivers measurable improvements in security, user experience, and operational efficiency for your card program.
Eliminate Card-Not-Present Fraud
Integrate on-card fingerprint authentication to replace static PINs and passwords. We deliver a certified biometric module that reduces CNP fraud by up to 95% and shifts liability away from your program.
Seamless, Frictionless User Onboarding
Deploy a white-label mobile SDK for biometric enrollment and card management. We ensure a sub-60-second enrollment flow, increasing activation rates and reducing support calls for lost PINs.
Future-Proof Compliance & Interoperability
Our architecture is built on EMV® 3-D Secure 2.0 and PCI DSS standards. We ensure your program is ready for SCA (Strong Customer Authentication) regulations and global payment network interoperability.
Accelerate Time-to-Market
Leverage our pre-certified hardware and software stack. We deliver a complete integration package, from secure element provisioning to backend API connectors, reducing your development timeline from months to weeks.
Biometric Security vs. Traditional Authentication
A technical breakdown of how biometric card integration fundamentally upgrades security and user experience compared to legacy authentication methods for Web3 applications.
| Authentication Factor | Traditional PIN/Password | Biometric Card (Chainscore) |
|---|---|---|
Security Model | Knowledge-based (Something you know) | Inherence-based (Something you are) |
Phishing/Skimming Risk | High | Near Zero |
On-Chain Transaction Signing | Manual, Multi-step | Single-tap, On-card |
Hardware Security Module (HSM) Integration | External device required | Embedded Secure Element (EAL6+) |
User Onboarding Friction | High (Seed phrase management) | Low (Fingerprint enrollment) |
Compliance (e.g., PSD2 SCA) | Requires 2FA overlay | Inherently compliant (Biometric = Inherence) |
Average Auth Time | 15-30 seconds | < 2 seconds |
Implementation Timeline for Your App | 4-8 weeks (SDK integration) | 2-4 weeks (Full-stack API/SDK) |
Ongoing Support & Updates | Your responsibility | Managed by Chainscore |
Total Cost of Ownership (Year 1) | $50K-$150K+ (dev, security, support) | $15K-$50K (predictable subscription) |
Our Integration Methodology
A structured, security-first approach to integrating biometric authentication into your Web3 payment cards, ensuring compliance, performance, and a seamless user experience.
Architecture & Security Audit
We begin with a comprehensive security review of your existing smart contracts and card infrastructure. Our team maps potential attack vectors and designs a zero-trust integration layer, ensuring biometric data never touches the blockchain directly.
Hardware & Protocol Selection
We guide you in selecting certified biometric hardware (FIDO2/WebAuthn compliant) and the optimal on-chain verification protocol (e.g., zk-SNARKs for privacy). We handle the SDK integration for fingerprint, facial, or iris recognition.
Smart Contract Gateway Development
Our engineers develop and audit custom, gas-optimized smart contracts that act as a secure gateway. These contracts verify off-chain biometric attestations before authorizing on-chain transactions or minting session keys.
End-to-End Testing & Compliance
We conduct penetration testing, simulate real-world attack scenarios, and ensure full compliance with GDPR, CCPA, and financial regulations (PSD2/SCA). We deliver a detailed audit report and certification readiness package.
Deployment & Key Management
We manage the phased deployment to testnet and mainnet, including secure provisioning of administrative keys and setting up multi-sig governance for contract upgrades. We ensure zero downtime during cutover.
Monitoring & Incident Response
Post-launch, we provide 24/7 monitoring of auth success/failure rates, fraud patterns, and contract health. Our team is on-call for immediate incident response and provides quarterly security review updates.
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the backbone of your protocol. Our development process ensures security-first design, gas optimization, and comprehensive testing before mainnet deployment.
- Full Lifecycle Development: From initial concept and architecture to deployment and post-launch maintenance.
- Security Audits: All contracts undergo rigorous internal review and can be prepared for third-party audits from firms like OpenZeppelin or CertiK.
- Protocol Standards: Expertise in
ERC-20,ERC-721,ERC-1155, and custom implementations for DeFi, NFTs, and DAOs.
Reduce your time-to-market with battle-tested Solidity patterns and avoid costly vulnerabilities.
Our engineers deliver modular, upgradeable code using industry standards like the Proxy Pattern and libraries such as OpenZeppelin Contracts. We focus on gas-efficient logic to minimize user transaction costs and provide clear documentation for your team.
Frequently Asked Questions
Get clear answers on our process, security, and timelines for integrating biometric authentication into your payment cards.
Our standard engagement follows a 4-phase process: Discovery & Architecture (1 week), Secure Element Integration (2-3 weeks), SDK & API Development (2-3 weeks), and Testing & Certification (1-2 weeks). A typical end-to-end deployment for a new card program takes 6-9 weeks. For existing card platforms, integration can be as fast as 4 weeks.
