Custom Blockchain Development
Design and deploy secure, scalable blockchain networks tailored to your business logic.
- Core Protocol Design: Custom
EVMorSubstrate-based chains,PoS/PoAconsensus, and cross-chain bridges. - Full-Stack Deployment: Node infrastructure, block explorers (
Blockscout), wallets, andRPCendpoints. - Enterprise Integration: APIs for legacy systems,
KYC/onboarding modules, and regulatory compliance tooling.
Move from concept to a live, maintainable network with a dedicated team of protocol engineers. We handle the complexity so you can focus on your product.

PROVEN FRAMEWORK
Our Audit Methodology for AA Protocols
A structured, multi-layered approach designed to secure the unique complexities of Account Abstraction, from EntryPoint contracts to custom paymasters.
01
Architecture & Specification Review
We begin by analyzing your protocol's architecture against ERC-4337 and ERC-6900 standards, identifying systemic risks in the interaction between Bundlers, Paymasters, and Account Factories before a single line of code is audited.

Core Standard
ERC-6900
Modular Standard
02
Smart Contract Security Analysis
Manual and automated review of core AA components—EntryPoint, Smart Account, Paymaster, and Aggregator logic—focusing on reentrancy, gas griefing, signature validation, and deposit management vulnerabilities.

03
Integration & Systemic Testing
We test the integration of your AA stack with external dependencies (like bundler services) and simulate complex user operation flows to uncover edge cases in validation, execution, and fee sponsorship.

Gas Optimization & Economic Review
Critical for AA adoption. We analyze gas consumption patterns for user operations, paymaster subsidies, and bundler incentives to ensure your protocol is economically viable and resistant to denial-of-service attacks.

EXPERTISE YOU CAN TRUST
Why Founders and CTOs Choose Our AA Audits
We deliver more than a checklist. Our audits are designed to protect your protocol's assets, ensure seamless user experience, and provide the technical confidence needed to launch with conviction.
01
Deep Protocol-Specific Expertise
Our auditors are active developers in the AA ecosystem, with hands-on experience building ERC-4337 Bundlers, Paymasters, and Account Factories. We find vulnerabilities others miss because we understand how the protocols work in production.

Business Logic & Economic Security
We go beyond code to audit your protocol's economic model and incentive structures. We identify risks in fee mechanisms, deposit/withdrawal flows, and sponsor logic that could lead to financial loss or system instability.
