As reported by The Defiant, Block is seeking an OCC license for Builders Bank—a custody bank for bitcoin and stablecoins without deposit insurance. The application currently requires OCC approval.

According to the published description, Builders Bank is intended to operate under direct federal supervision, neither accepting deposits nor issuing loans. The source does not report a regulatory decision or review timelines.

The significance of the application lies in proposing crypto custody within a separate banking structure under federal supervision. However, available materials represent only a synopsis of The Defiant's publication, so details of the model and potential consequences remain unclear.
