If approved, Builders Bank would operate as a federally regulated national trust bank under OCC supervision and would provide custody and related fiduciary services, including for bitcoin and stablecoins. The charter would allow Block to support these activities through a consistent national framework as the business scales. Builders Bank would be an uninsured, non-deposit-taking national trust bank and would not accept deposits or make loans. The proposed charter would establish a federal supervisory framework for certain custody and related activities currently offered by Block.
