Frequently Asked Questions
Common questions from CTOs and technical leaders evaluating our institutional-grade account abstraction development services.
From initial design to mainnet deployment, a standard implementation takes 4-6 weeks. This includes smart contract development, integration with your existing treasury or ERP systems, and comprehensive security audits. For more complex requirements like multi-chain deployments or custom signature schemes, timelines are scoped individually, typically ranging from 8-12 weeks.
