Smart Contract Audit for KYC Logic

Specialized security auditing and formal verification of on-chain KYC, access control, and identity management smart contracts to ensure regulatory logic is correctly and securely implemented.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy custom Solidity and Rust smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis with Slither and manual review by our security team, before deployment to Mainnet.

  • Custom Tokenomics: Design and implement ERC-20, ERC-721, and ERC-1155 tokens with tailored minting, vesting, and governance logic.
  • DeFi Protocols: Build core components like Automated Market Makers (AMMs), lending pools, and staking mechanisms with gas-optimized code.
  • Enterprise Logic: Develop complex business logic for DAOs, supply chain tracking, and real-world asset tokenization.

We deliver a fully documented, tested, and deployable contract suite in 2-4 weeks, backed by a 99.9% uptime SLA for on-chain operations.

PROVEN FRAMEWORK

Our KYC-Specific Audit Methodology

We apply a specialized, multi-layered audit process designed explicitly for KYC/AML logic, ensuring compliance without compromising on-chain performance or user privacy.

01

Compliance Logic Verification

We verify that your smart contract logic correctly enforces jurisdictional rules, whitelist/blacklist management, and tiered access controls as defined in your legal framework.

Frequently Asked Questions

Get clear answers about our specialized audit process for KYC, identity, and compliance-focused smart contracts.

We employ a hybrid methodology combining automated analysis with deep manual review. Our process includes: 1) Static Analysis using Slither and MythX to detect common vulnerabilities. 2) Manual Code Review focused on business logic flaws, access control, and compliance rule enforcement. 3) Scenario Testing simulating user journeys and edge cases for identity verification, whitelisting, and role-based permissions. 4) Formal Verification for critical state transitions. This multi-layered approach ensures we catch both technical bugs and logical inconsistencies in your compliance workflows.
