A “crypto trust bank” is usually shorthand for a national bank chartered by the Office of the Comptroller of the Currency (OCC) for trust-company operations and related activities—not a single nationwide crypto-bank category. A state-chartered trust company gets its powers from a particular state’s law and regulator. Neither label, by itself, tells you whether the institution can take deposits, has FDIC-insured accounts, or is approved to provide every crypto service it advertises.
What the two charter types mean
The most important difference is who grants the charter and which law defines the institution’s powers. An OCC national trust bank is chartered under federal law, including 12 U.S.C. § 27(a). A state-chartered trust company is organized under a state’s banking law and overseen by that state’s banking regulator. State rules are not uniform; New York is a useful example, not a stand-in for all states.
“Crypto trust bank” is a descriptive phrase, not a legal category that guarantees a standard set of crypto permissions. For a named firm, identify its exact charter, regulator, approved activities, and any conditions attached to its approval.
Key differences at a glance
| Question | OCC national trust bank | State-chartered trust company |
|---|---|---|
| Who grants the charter? | The OCC under the National Bank Act, including 12 U.S.C. § 27(a). The OCC’s Interpretive Letter 1176 describes this authority. | The relevant state regulator under that state’s law. In New York, the Department of Financial Services (DFS) charters and regulates banks and trust companies under Article III of the Banking Law. |
| What activities may it conduct? | Permissible trust-company operations and related activities. OCC Interpretive Letter 1176 says these can include non-fiduciary activities such as custody; the particular charter and applicable requirements still govern. | Activities depend on state law, the institution’s charter documents, and regulator-imposed conditions. New York limited-purpose trust companies have specific limits. |
| Who defines fiduciary powers? | Federal law, including 12 U.S.C. § 92a and 12 C.F.R. Part 9, governs national banks acting in a fiduciary capacity. | State law and charter terms. New York Banking Law § 100, for example, enumerates certain fiduciary powers subject to other statutory restrictions. |
| Can it take deposits or make loans? | Do not infer either power from the words “national trust bank.” Check the institution’s charter, approved business plan, and status. | It varies by state and charter. New York limited-purpose trust companies generally may not take deposits or make loans except where directly arising from fiduciary powers. |
| Are its accounts FDIC-insured? | Not necessarily. A trust-bank charter name does not establish deposit insurance; check the institution and the specific account. | Not necessarily. New York’s limited-purpose trust company application process has exceptions concerning FDIC insurance requirements. Other states may set different rules. |
| Does the charter authorize crypto services? | The OCC has recognized national-bank authority to provide crypto custody, but the service and current supervisory requirements matter. | State approval may be required. In New York, DFS says virtual-currency business activity under a banking charter requires Superintendent approval. |
What an OCC national trust bank can do—and what that does not mean
Under 12 U.S.C. § 27(a), the OCC may charter a national bank whose operations are limited to those of a trust company and related activities. In Interpretive Letter 1176, dated January 11, 2021, the OCC explained that trust-company operations can include both fiduciary work and non-fiduciary functions, including custody. A trust bank therefore is not necessarily limited to acting as a trustee.

Fiduciary status is a separate legal question. National-bank fiduciary activities are addressed by 12 U.S.C. § 92a and 12 C.F.R. Part 9. The fact that an institution has a national trust-bank charter does not make every service it provides fiduciary activity, nor does it mean every service is automatically permitted.
On April 1, 2026, an OCC final rule amended its chartering regulation to clarify the language concerning trust-company operations and related activities. OCC Bulletin 2026-4 described the rule as clarifying longstanding authority for national trust banks to conduct non-fiduciary activities as well as fiduciary ones; it also said the rule “would neither expand nor contract the OCC’s authority to charter a national bank.” A bank remains subject to applicable statutes, regulations, supervisory requirements, and conditions in its own charter or approval.

How a state trust company differs: the New York example
A state trust company is not one standardized product across the United States. Its state’s statutes and regulator determine its powers and restrictions. New York DFS says it charters and regulates banks and trust companies under Article III of the Banking Law. The state’s limited-purpose trust company guidance describes a charter without general deposit-taking or lending powers: deposits and loans are generally prohibited except when directly arising from fiduciary powers.
In New York, the institution’s organization certificate and approval conditions help define the actual products, services, and activities it may offer. DFS says a limited-purpose trust company may not materially change those activities without prior Superintendent approval. The application process has exceptions concerning minimum capitalization and FDIC insurance requirements; that does not establish that every New York trust company—or any particular customer account—is insured or uninsured.

New York Banking Law § 100 lists fiduciary powers that can include acting as a fiscal or transfer agent and serving as trustee under certain instruments, subject to other provisions of the law. These details illustrate why a state charter must be assessed under its own statute and documents rather than generalized from the word “trust.”
Crypto custody is not the same as permission for every crypto service
In July 2020, the OCC stated that national banks and federal savings associations may provide cryptocurrency custody, including holding the associated unique cryptographic keys. That guidance addresses custody; it should not be read as blanket approval for trading, exchange operation, payments, stablecoin issuance, or every other digital-asset activity.

In November 2021, the OCC said that certain crypto, distributed-ledger, and stablecoin activities discussed in earlier interpretive letters could be conducted after a bank notified its supervisory office and received written non-objection. The OCC also retained discretion to determine whether an activity is fiduciary for federal-law purposes. That was dated guidance, not a timeless rule for every activity: verify the current requirements that apply to the specific bank and service.
For New York institutions, DFS says a firm may conduct virtual-currency business activity through a New York Banking Law charter, including a limited-purpose trust company or state bank, if it receives Superintendent approval. DFS distinguishes a limited-purpose trust company’s fiduciary powers from the BitLicense framework. A state trust charter alone does not establish that the firm has received the approvals needed for its proposed crypto activities.

What conditional approvals and application lists establish
An application, conditional approval, charter, and permission to begin a particular service are different status points. The OCC’s Digital Assets Licensing Applications page describes its table as pending applications from entities planning to offer digital-asset products or services. As listed on the page reviewed October 7, 2026, it included applicants such as zerohash National Trust Bank, Dakota National Trust Bank, Payward National Trust Company, and EDX Trust. A pending listing is not evidence that an applicant has been approved or is operating.
The OCC’s December 12, 2025 conditional approval letter for Ripple National Trust Bank described proposed cryptocurrency custody and collateral trustee services. It identified Standard Custody & Trust Company, LLC as a New York limited-purpose trust charter regulated by NYDFS. The letter’s conditional approval describes that case at that point in time; it is not, by itself, proof that the proposed services are operating or that all conditions have been met.
In the same 2025 letter, the OCC reported that OCC-supervised uninsured national trust banks had $6.8 trillion in assets under administration as of September 30, 2025, including $1.6 trillion in custody and safekeeping accounts and $5.2 trillion in fiduciary accounts. These are OCC-reported aggregate figures for those banks, not crypto-only totals or measures of assets held for any one customer.
Quick Recap
How to check a particular institution before relying on its services
- Identify the exact legal entity and charter. Do not rely on a brand name or the phrase “crypto trust bank.” Determine whether the firm is an OCC national bank, a state-chartered trust company, or a different kind of entity.
- Check the chartering regulator’s current record. For a national trust bank, consult OCC charter and approval information. For a state trust company, consult the relevant state regulator; for New York, that is DFS.
- Read the actual approval documents. Look for the charter, organization certificate, approval order, and any conditions or limits on products and services. A proposed service may not be authorized merely because it appears in an application or announcement.
- Match the approval to the service you intend to use. Custody, fiduciary administration, trading, exchange services, payments, and stablecoin activity are not interchangeable. Confirm the institution’s authority for the specific activity.
- Verify deposit and insurance status for the specific account. Ask whether the product is a deposit account, whether the institution is FDIC-insured, and whether the account is eligible for coverage. Do not assume that crypto custody or a trust-bank charter means customer assets are FDIC-insured.
- Check status close to the time you act. Applications and approval conditions can change. A pending application or conditional approval should not be treated as proof of current operations.
