Block Files Application for Federal Bitcoin Custody Bank

Olivia Carter 09.09.2026

A Specialized Model for Digital Asset Safeguards

Block Inc. has submitted a formal application to the Office of the Comptroller of the Currency. The company seeks a national charter for a new entity named Builders Bank and Trust. This proposed institution would function as an uninsured national trust bank. It aims to provide custody services specifically for Bitcoin and stablecoins. The move places digital asset management under direct federal oversight.

The application outlines a distinct operational model for the new bank. Unlike traditional commercial banks, Builders Bank will not accept customer deposits. It also plans to refrain from issuing loans to the general public. Instead, the institution focuses exclusively on safeguarding digital assets. This specialized approach allows the bank to serve institutional clients holding significant crypto portfolios. The structure separates custody functions from standard banking activities.

The proposed bank operates under a specific regulatory framework. It will hold a national trust bank charter rather than a full-service banking license. This distinction is crucial for its business strategy. The entity can manage trust accounts containing cryptocurrency without mixing those assets with depositors' funds. Investors often prefer this separation for risk management purposes. It provides a clear legal boundary between the custodian and the asset owner. The OCC review process will determine if this model fits current federal standards.

Why Uninsured Status Matters for Crypto Holders

Block executives believe this structure offers superior transparency. Direct federal supervision ensures consistent compliance checks. The bank would report directly to regulators regarding its operations. This level of scrutiny addresses common concerns about private custody providers. Many institutions currently rely on offshore entities or private companies for storage. A federally chartered bank brings a higher degree of accountability. The trust bank status allows it to act as a fiduciary. Clients can appoint the bank to manage their digital wealth securely.

One defining feature of Builders Bank is its uninsured nature. The Federal Deposit Insurance Corporation does not cover its assets. This means that if the bank fails, client holdings are not automatically protected by FDIC insurance. However, the trust structure provides a different layer of protection. Assets held in trust are legally separated from the bank's own balance sheet. In a bankruptcy scenario, these digital assets remain property of the clients. They do not become part of the estate available to creditors. This legal separation offers substantial safety despite the lack of deposit insurance.

The absence of loan-making powers further reduces complexity. The bank cannot leverage client assets to generate interest income through lending. This conservative approach minimizes counterparty risk. Regulators may view this limited scope favorably. It aligns with the goal of creating a safe harbor for digital assets. The application highlights a growing trend in financial regulation. Authorities are adapting frameworks to accommodate new asset classes.
