Invoice Smart Contract Security Audit FAQ
Common questions from CTOs and founders about our specialized security audit process for invoice and payment-related smart contracts.
We employ a three-phase methodology tailored for financial logic. Phase 1: Automated Analysis uses Slither and Foundry to flag common vulnerabilities. Phase 2: Manual Code Review focuses on business logic flaws, tokenomics, and access control specific to invoicing (e.g., payment escrow, dispute resolution, fee calculations). Phase 3: Functional Testing simulates real-world payment flows and edge cases. This process has secured over $500M+ in transaction volume across 50+ financial dApps.
