CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production and scale.
- Security-First Development: Built with
Solidity 0.8+andOpenZeppelinlibraries, following industry-standard security patterns. - Comprehensive Audits: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
- Gas Optimization: We write efficient code to minimize transaction fees, a critical factor for user adoption.
We don't just write code; we deliver the secure, audited digital agreements your business runs on.

EXPERTISE YOU CAN TRUST
Why Choose Chainscore for AA Security
We deliver actionable security insights for Account Abstraction wallets, not just generic vulnerability lists. Our testing is designed to protect user assets and ensure protocol compliance.
01
Protocol-Specific Expertise
Our engineers are certified in ERC-4337, ERC-6900, and major AA SDKs (ZeroDev, Biconomy, Alchemy). We test for bundler manipulation, paymaster exploits, and signature validation flaws specific to smart accounts.

ERC-6900
Modular Standard
02
Full-Stack Attack Surface Analysis
We assess the entire AA stack: smart account logic, bundler RPC endpoints, paymaster dependencies, and frontend integration. This prevents cross-layer exploits that isolated contract audits miss.

Frequently Asked Questions
Get clear answers about our penetration testing process, timeline, and deliverables for your AA wallet or smart account project.
Our methodology is a hybrid approach combining automated scanning with deep manual review. We test against the ERC-4337 standard, EIP-1271 signature validation, and custom account logic. The process includes: 1) Architecture Review of your bundler, paymaster, and entry point setup. 2) Smart Contract Audits focusing on custom account, factory, and handler logic. 3) Integration Testing for frontend <> SDK <> contract interactions. 4) Economic & Gas Analysis to identify denial-of-service vectors. We use proprietary tools and follow OWASP Web3 Security Testing guidelines.
