overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific use case and audited to enterprise standards.
From tokenomics to governance, we translate your requirements into efficient, gas-optimized code.
- End-to-End Development: Full lifecycle from architecture and
Solidity/Rustcoding to testing and mainnet deployment. - Security Audits: Every contract undergoes internal review and optional third-party audits (e.g., CertiK, Quantstamp) before launch.
- Protocol Integration: Seamless integration with DeFi primitives (Uniswap V3, Aave), NFT standards (ERC-721A), and cross-chain bridges.

Build vs. Buy: Biometric Module Strategy
A direct comparison of the total cost, risk, and time investment required for developing a privacy-enhanced biometric wallet module in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Chainscore Module |
|---|---|---|
Time to Market | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security Audit & Penetration Testing | Additional $50K-$100K | Included |
Ongoing Maintenance & Updates | 2-3 FTE Engineers | Optional SLA from $30K/year |
Zero-Knowledge Proof Expertise Required | High (Hire specialized team) | Built-in (Our core competency) |
Regulatory Compliance (GDPR, CCPA) | Your legal team's responsibility | Architected for compliance by design |
Integration Complexity | High (Custom SDK, API, docs) | Low (Pre-built SDK & documentation) |
Total Year 1 Cost (Est.) | $300K - $700K+ | $80K - $180K |
Key Risk | High (Unaudited code, talent gap) | Low (Audited, battle-tested modules) |

A SECURE, AUDITED PIPELINE
Our Development & Integration Process
We deliver production-ready, privacy-enhanced biometric modules through a rigorous, four-phase process designed for security, speed, and seamless integration with your existing wallet or dApp.
01
Architecture & Threat Modeling
We begin with a zero-trust security assessment, defining data flows, threat vectors, and cryptographic primitives (zk-SNARKs, MPC) to protect biometric templates. This phase establishes the formal security guarantees for your module.

Frequently Asked Questions
Get clear answers on our development process, security, and support for your secure identity solution.
A standard Privacy-Enhanced Biometric Wallet Module deployment takes 4-8 weeks from kickoff to production. This includes a 2-week discovery and design phase, 3-5 weeks of core development and integration, and 1 week for security hardening and final deployment. Complex multi-chain integrations or custom biometric modalities may extend this timeline, which we scope and quote for upfront.
