CLIENT-CENTRIC EXECUTION
Our Delivery & Integration Process
A structured, transparent workflow designed to integrate our Account Abstraction solutions into your stack with minimal friction and maximum security.
01
Discovery & Architecture Review
We conduct a technical deep-dive to map your user flows, wallet requirements, and existing infrastructure. This phase defines the optimal AA stack (ERC-4337, Safe{Core}, or custom) and integration strategy.
