Cairo StarkNet Account Audit

We audit the core validateUserOp function for logic flaws, signature replay risks, and compliance with ERC-4337 and StarkNet's AA standards. Ensures only authorized operations are executed.

Security review of sponsor logic, token approval flows, and deposit management. Prevents gas griefing attacks and ensures reliable transaction sponsorship for your users.

Analysis of guardian management, recovery delay timers, and signature aggregation. Mitigates risks of unauthorized recovery and ensures robust key management.

Review of transaction batching, call data decoding, and internal call permissions. Prevents reentrancy and ensures atomic execution of complex user operations.

Security assessment of proxy patterns, upgrade authorization, and timelock mechanisms. Ensures secure, governance-controlled evolution of your account infrastructure.

Line-by-line Cairo bytecode analysis to identify and remediate gas inefficiencies. Reduces user transaction costs by an average of 15-40% based on implementation.

We identify logic flaws unique to Cairo VM, such as storage pointer manipulation, felt252 overflow risks, and system call misconfigurations that generic auditors overlook.

Deep audit of your account contract's validation logic, paymaster integrations, and signature schemes to prevent unauthorized transactions and fund drainage.

Comprehensive analysis of message passing, contract upgrades via proxies, and bridge integrations to eliminate cross-layer exploit vectors.

Review of L1→L2 message costs, storage write patterns, and fee payment logic to prevent economic attacks and ensure user transaction reliability.

We structure your code and provide specifications to prepare for formal verification tools, delivering mathematically provable security for critical functions.

Alignment with OpenZeppelin's Cairo contracts, StarkWare security recommendations, and established patterns to ensure long-term maintainability and safety.
