DELIVERABLES
Business Outcomes for Your Mobile App
Account abstraction transforms mobile UX from a technical hurdle into a competitive advantage. Here’s what our implementation delivers for your product.
01
Seamless User Onboarding
Replace seed phrases with familiar Web2 logins (email, social, biometrics). We implement ERC-4337 smart accounts with social recovery, removing the #1 barrier to user adoption.
