COMPREHENSIVE SECURITY REVIEW
What We Audit in Your Batch System
Our audit methodology systematically examines every critical layer of your batch transaction system, from core logic to economic incentives, ensuring robust security and operational integrity before mainnet deployment.
01
Batch Logic & State Management
We verify the atomicity and correctness of batch execution, ensuring state transitions are consistent, revert properly on failure, and prevent double-spending or invalid state updates.

State Corruption
02
Fee & Reward Distribution
Audit of the economic engine, ensuring fee calculations are accurate, reward distributions are fair and resistant to manipulation, and no funds can be locked or misdirected.

03
Access Control & Authorization
We map and test all privileged functions (batch submission, pausing, parameter updates) to ensure strict, multi-signature or timelock-based controls are enforced to prevent admin abuse.

04
Front-Running & MEV Resistance
Analysis of transaction ordering, deadline enforcement, and slippage mechanisms to identify and mitigate vulnerabilities to sandwich attacks and other forms of miner-extractable value.
