Zero-Knowledge KYC for Compliant Lending

We implement a privacy-preserving KYC verification layer using zero-knowledge proofs. Your platform proves regulatory compliance without storing or exposing users' personal identity data on-chain.
Chainscore © 2026
overview
CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that form the backbone of your protocol. Our development process is built on security-first principles and gas optimization from day one, ensuring your application is both resilient and cost-effective to run.

  • Protocol Development: Custom ERC-20, ERC-721, ERC-1155, and bespoke token standards.
  • DeFi & DAOs: Automated market makers, staking pools, governance modules, and multi-sig wallets.
  • Security Audits: All code undergoes internal review and is prepared for third-party audits by firms like CertiK or OpenZeppelin.

We deliver battle-tested contracts with comprehensive documentation, enabling your team to integrate and scale with confidence.

TRANSPARENT & PREDICTABLE

Our Delivery Process: From Audit to Integration

A structured, milestone-driven approach that ensures your compliant lending platform is built on a secure, scalable, and regulator-ready foundation. We deliver certainty, not just code.

01

1. Compliance & Architecture Audit

We conduct a deep-dive analysis of your lending logic, data flows, and jurisdictional requirements. We deliver a detailed architecture blueprint and compliance gap analysis, ensuring your ZK-KYC design meets FINRA, FATF, and GDPR standards from day one.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic.

We architect and deploy custom smart contracts on EVM and Solana that are audit-ready from day one. Our development process is built on battle-tested patterns from OpenZeppelin and Solana Program Library to ensure security and efficiency.

  • End-to-End Development: From initial design and Solidity/Rust coding to deployment and mainnet verification.
  • Security-First Approach: Every contract undergoes internal review against common vulnerabilities (reentrancy, overflow) before external audit.
  • Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption.
  • Integration Support: Seamless connection to frontends, oracles, and other protocol components.

Deliver a secure, functional MVP in as little as 2-3 weeks, with full documentation and a clear path to audit.

Zero-Knowledge KYC

Frequently Asked Questions

Get clear answers on how our privacy-preserving identity verification integrates with your lending protocol.

Borrowers submit identity documents to a licensed, accredited KYC provider. Upon successful verification, the provider issues a zero-knowledge proof (ZKP) attestation. This proof is submitted on-chain to your lending smart contract, which verifies its cryptographic validity without exposing any personal data. The contract then grants the verified wallet address permission to borrow up to compliant limits. We handle the full integration with providers like Veriff or Sumsub and the ZK circuit logic.
