Recurring Billing Smart Contract Auditing & Formal Verification

We begin by analyzing your business logic and formalizing requirements into precise specifications. This ensures the contract's intended behavior is unambiguously defined before a single line of code is reviewed.

Leverage industry-standard tools (Slither, MythX) and proprietary scanners to detect common vulnerabilities (reentrancy, overflow) and gas inefficiencies across 500+ known issue patterns.

Our senior auditors conduct a deep, manual inspection of all logic flows—focusing on subscription lifecycle, payment routing, access control, and upgrade mechanisms—to find flaws tools miss.

We optimize contract execution costs and enforce Ethereum/Native chain best practices (ERC standards, CEI patterns) to reduce user fees and future integration risks.

We provide prioritized fixes, re-audit the corrected code, and deliver a final verification report with actionable insights for your team and stakeholders.

We mathematically prove the correctness of your core subscription and payment logic, eliminating entire classes of financial bugs that traditional audits miss. This is critical for automated, high-value transactions.

Our team has built and secured live subscription protocols. We audit not just for security, but for economic soundness, gas efficiency, and integration risks specific to recurring billing models.

Receive clear, prioritized findings with direct code snippets, exploit scenarios, and fixed code solutions. We integrate with your PR process to streamline remediation, not just report problems.

Our audit process and final report are structured to satisfy due diligence requirements from enterprises, payment processors, and regulators, accelerating your enterprise sales cycles.
