A Few Words About The Client

Custodial Wallet is a mobile-first cryptocurrency wallet that gives users a simple, secure way to hold and transfer digital assets. Block Intelligence designed and built the app with a focus on ease of use for non-technical users while maintaining institutional-grade key management and compliance-ready features.

The client wanted to offer a custodial wallet experience so users could recover access via email/password without managing private keys, while still ensuring security and regulatory clarity. They needed a single codebase that could scale across iOS and Android and integrate with existing back-office systems.
