Custodial Wallet
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.
Project Requirements
Our Solution & Results
We delivered a cross-platform mobile app backed by a secure wallet service. Keys are generated and stored in a hardened backend with strict access controls and audit logging. The app supports multiple chains and tokens, with clear UX for sends, receives, and recovery. We integrated with the client's identity and support systems.
The wallet launched on both app stores and has been used by thousands of users. Security audits confirmed our key handling and access controls. Support and compliance teams use the admin tools daily for faster resolution and reporting.
