Account Abstraction Gas Sponsorship Model Review

In-depth review of your paymaster and account factory contracts for vulnerabilities, focusing on reentrancy, access control, and gas griefing attacks. We provide remediation steps based on OpenZeppelin best practices.

Analysis of your sponsorship logic to identify inefficiencies and prevent abuse. We benchmark your model against industry standards to recommend optimal gas policies and rate limits.

Evaluation of the end-to-end transaction flow from sign-up to sponsored transaction. We identify friction points and recommend improvements for a seamless, non-custodial onboarding experience.

Assessment of your system's architecture for handling high transaction volumes and multi-chain deployments. We provide guidance on relayers, bundler integration, and failover mechanisms.

Review of your sponsorship policies for regulatory considerations, including OFAC sanctions screening integration, transaction monitoring, and anti-abuse mechanisms to mitigate financial risk.

A prioritized list of technical tasks with clear specifications to address findings. We provide code snippets, configuration examples, and integration steps for your engineering team.

We analyze and redesign your gas sponsorship flows to eliminate wallet setup and token acquisition barriers, directly increasing user activation rates and reducing drop-off.

Gain visibility and control over gas expenditure with our cost-optimization models. We implement smart sponsorship policies and usage caps to prevent budget overruns.

Our audit ensures your sponsorship logic is resilient against abuse, implements rate-limiting, and adheres to regulatory best practices for transaction funding.

Receive a future-proof technical design for your gas engine, supporting multi-chain deployments, paymaster integrations (like Biconomy, Stackup), and automated replenishment.

We analyze your current AA stack—from paymaster contracts to bundler integration—against industry standards like ERC-4337 and ERC-7579. We identify architectural flaws and single points of failure.

Comprehensive review of paymaster logic, signature validation, and dependency security. We map attack vectors specific to gas sponsorship, including replay attacks and economic exploits.

We model your sponsorship costs under real-world load, simulate MEV scenarios, and benchmark against L2 fee markets. Our goal: optimize your cost-per-user without compromising UX.

We stress-test your system's capacity, review multi-chain strategies, and provide a roadmap for integrating emerging AA standards to prevent technical debt.

Receive a prioritized, executable report with code snippets, configuration changes, and implementation timelines. We translate findings into clear engineering tasks.

Includes a dedicated session with our AA experts to walk through the report and answer implementation questions. We ensure your team can execute the changes with confidence.
