Zerohash, a Chicago-based provider of crypto infrastructure, has resubmitted its application for a U.S. national trust bank charter to the Office of the Comptroller of the Currency following a return of the July filing for missing materials.

The OCC said the July 17 submission was returned because it lacked sufficient materials.

Zerohash described the return as an administrative step that enables a fresh filing this month and said it does not affect its current operations. The company noted that the initial filing encompassed a broad set of digital asset and fiduciary services, and it has chosen a phased approach that targets national trust banking activities that align with its launch timeline.

Headquartered in Chicago, Zerohash provides back-end crypto infrastructure services to institutions including Morgan Stanley's E*Trade, BlackRock, Franklin Templeton, Stripe, Interactive Brokers, and DraftKings. The company already holds a state trust bank charter.
