PREDICTABLE, SECURE DEPLOYMENT
Our Delivery Process: From Audit to Mainnet
A structured, four-phase methodology designed for technical leaders who need security, speed, and certainty when deploying Account Abstraction infrastructure.
01
Phase 1: Security & Architecture Audit
We conduct a comprehensive review of your existing smart accounts, bundler logic, and paymaster integrations. We identify vulnerabilities in user operation validation, gas sponsorship rules, and reentrancy risks specific to ERC-4337.
48 hrs
