Frequently Asked Questions
Get clear answers on our process, security, and timelines for integrating smart account infrastructure into your channel-based application.
A standard integration, including design, development, and testing, takes 2-4 weeks. This timeline is for a typical channel application (e.g., social, gaming, content) with standard features like gas sponsorship, batched transactions, and session keys. Complex requirements like custom multi-sig recovery or novel bundler logic can extend this to 6-8 weeks. We provide a detailed project plan within 48 hours of scoping.
