A year ago, "crypto bank" was mostly a marketing phrase. In 2026 it describes something real: companies holding bank-style charters that let them safeguard digital assets under the same kind of supervision that applies to traditional trust banks. Here's what the term means now, and what it doesn't.
The short definition
A crypto bank is a regulated financial institution that offers banking-style services for digital assets. The core service is custody: holding the private keys to customers' crypto in audited, insured, segregated storage. Most also connect crypto to the dollar system, letting money move between bank accounts, stablecoins and digital assets.
What most U.S. crypto banks cannot do is take deposits or make loans the way a regular bank does. That distinction matters more than any other in this article.
The four kinds of crypto bank in the U.S.
| Type | Regulator | What it can do |
|---|---|---|
| National trust bank | OCC (federal) | Custody and fiduciary services nationwide; no deposits or loans |
| State limited purpose trust | State banking regulator, e.g. NYDFS | Custody and fiduciary services; no general deposit-taking |
| Wyoming SPDI | Wyoming Division of Banking | Full-reserve deposits of crypto and dollars; no lending |
| Traditional bank with crypto services | OCC, Fed, FDIC, state | Normal banking, plus crypto custody or trading |
National trust banks
In December 2025 the OCC conditionally approved national trust bank charters for Circle, Ripple, BitGo, Fidelity Digital Assets and Paxos. Crypto.com followed in February 2026, along with Stripe's Bridge, and Circle received final approval in July 2026. A national charter replaces a patchwork of state licenses with a single federal supervisor.
New York trust companies
New York got here first. Paxos and Gemini became limited purpose trust companies under New York Banking Law in 2015, and Coinbase, BitGo, MoonPay and, as of July 2026, Circle hold the same kind of charter. These are supervised by the New York Department of Financial Services (NYDFS), widely considered the strictest crypto regulator in the country.
Wyoming SPDIs
Wyoming's Special Purpose Depository Institution charter was built for digital assets. In March 2026, Kraken Financial, a Wyoming SPDI, became the first crypto-native firm to receive a Federal Reserve master account, giving it direct access to Fed payment rails. Custodia Bank, another SPDI, lost its long court fight for the same access days later.
Is crypto at a crypto bank insured?
No. FDIC insurance covers U.S. dollar deposits at FDIC-insured banks. It does not cover cryptocurrency or stablecoins, and it never covers losses from price changes. When a crypto company says your funds are "insured," it usually means dollar balances held at a partner bank, or a private crime policy against theft from its own systems.
How to check a crypto bank before you use it
- Look up the charter yourself on the OCC or NYDFS website, not just the company's.
- Confirm customer assets are segregated from the company's own money.
- Ask whether it lends out customer crypto, and whether you can opt out.
- Read the attestations showing reserves match customer balances.
- Know where you are: New York residents need a firm with a BitLicense or New York trust charter.
The bottom line
"Crypto bank" now means a regulated custodian with a real charter behind it, not a high-yield app. That's a meaningful step for anyone holding crypto long term. It also means reading the fine print: a trust charter protects how your assets are held, not what they're worth.
