PROVEN PROCESS
Our B2B Payment Security Audit Methodology
Our systematic, four-phase methodology is designed to uncover critical vulnerabilities in your payment network's smart contracts and infrastructure, delivering actionable, prioritized findings.
01
Architecture & Code Review
Comprehensive analysis of your smart contract architecture, business logic, and codebase against industry standards (OWASP Top 10, SWC Registry) to identify design flaws and logic errors before active testing.
100%
Code Coverage
OWASP/SWC
Standards
02
Automated & Manual Penetration Testing
Combines advanced fuzzing, static/dynamic analysis tools (Slither, MythX) with expert manual exploitation to simulate real-world attacks on payment flows, access controls, and financial mechanisms.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy audited, gas-optimized smart contracts that form the backbone of your Web3 product. Our focus is on security-first development using Solidity 0.8+ and OpenZeppelin libraries, ensuring your core logic is resilient against exploits.
- Custom Tokenomics & DeFi Logic: Design and implement
ERC-20,ERC-721, and custom token standards with vesting, staking, and governance modules. - Full Audit Readiness: Code is developed with formal verification in mind, structured for seamless review by top security firms.
- Gas Optimization: Every contract is profiled and optimized to reduce user transaction costs by up to 40%.
- Mainnet Deployment & Verification: We handle the full deployment lifecycle on Ethereum, Polygon, or your chain of choice, with source code verification.
From initial spec to mainnet launch, we deliver contracts you can trust to handle millions in TVL.
Technical & Process Questions
B2B Payment Network Security Audit FAQs
Get clear answers on our security audit methodology, timeline, deliverables, and how we help secure your payment infrastructure.
We employ a multi-layered methodology combining automated scanning, manual code review, and adversarial testing. Our process includes: 1) Architecture Review (assessing smart contract design, access controls, and upgrade mechanisms), 2) Automated Analysis (using Slither, MythX, and custom tools), 3) Manual Code Review (line-by-line inspection by senior auditors), and 4) Penetration Testing (simulating real-world attacks on the live or testnet deployment). This approach has secured over $500M+ in transaction volume across 50+ DeFi and payment projects.
