INSTITUTIONAL-GRADE METHODOLOGY
Our Audit Framework
A systematic, multi-layered approach designed to meet the stringent requirements of financial institutions and regulated entities. We deliver more than a checklist—we provide a defensible, evidence-based security posture.
01
Comprehensive Threat Modeling
We begin with a structured analysis of your RNG's attack surface, identifying potential threats from front-running to entropy manipulation. This proactive foundation ensures our audit targets the highest-risk areas first.

Framework
02
Formal Verification & Symbolic Execution
Leveraging tools like Certora and Slither, we mathematically prove the correctness of critical logic (e.g., seed generation, fairness algorithms) to eliminate entire classes of vulnerabilities that manual review might miss.

Manual Code Review & Gas Optimization
Our senior auditors conduct line-by-line analysis of the entire codebase, focusing on logic flaws, reentrancy, and access control. We simultaneously optimize for gas efficiency, reducing operational costs by up to 40%.

Compliance & Regulatory Alignment
We map your RNG implementation against key standards like NIST SP 800-90A/B for entropy and GLI-33 for gaming compliance. Our reports include direct citations for regulator-ready documentation.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by expert Solidity engineers.
We architect and deploy custom smart contracts for tokens, DeFi protocols, and NFT projects. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and comprehensive audit trails.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing vaults, staking contracts.
- Security: Multi-signature deployment, formal verification, and third-party audit preparation.
- Delivery: Production-ready code with full documentation and a 2-week MVP turnaround for standard contracts.
We deliver contracts that are secure by design, reducing post-launch vulnerabilities and technical debt.
Institutional & Compliance Focus
RNG Audit FAQs
Get clear answers on our process, timeline, and security standards for Random Number Generator audits that meet institutional and regulatory requirements.
Our audit follows a rigorous, multi-phase methodology designed for institutional-grade scrutiny. Phase 1: Architecture Review assesses the RNG's design against NIST SP 800-90A/B/C standards and gaming/gambling compliance frameworks. Phase 2: Code & Logic Audit involves line-by-line review of the source code for entropy sources, seeding, and distribution algorithms, testing for bias, predictability, and manipulation vectors. Phase 3: Statistical Analysis runs the RNG through Chi-squared, Monte Carlo, and serial correlation tests with millions of iterations. Phase 4: Operational Security Review evaluates key management, on-chain verification, and oracle integration. We deliver a detailed report with findings, risk ratings, and actionable remediation guidance.
