BUILDING THE FOUNDATION
Core Technical Capabilities We Deliver
We architect and deploy the complete technical stack for your Account Abstraction wallet, from core smart accounts to seamless user onboarding. Each component is built for security, scalability, and a superior user experience.
01
Smart Account Factory & Deployment
We deploy a custom, audited Smart Account Factory contract (ERC-4337 compatible) to create and manage user-controlled smart contract wallets. This includes gas sponsorship logic, upgradeable entry points, and integration with major bundlers.
