Minnesota Banks Get Crypto Custody Green Light, but 60-Day Notice Limits Day-One Launches

Minnesota Crypto Custody Law Takes Effect

The state Legislature’s own new-law explainer says banks and credit unions can offer virtual-currency custody in a nonfiduciary capacity from Aug. 1. It also says the institution must notify Commerce 60 days before commencing and provide the nature of the service and its risk-management framework.

That sequencing matters. The effective date establishes the legal authority, but an institution that had not filed its notice by early June cannot begin the service immediately. The requirement does not itself mean Commerce pre-approves every provider; it creates an advance supervisory touchpoint and documents the controls an institution says it will use.

The law directs Commerce to examine virtual-currency custody as part of its regular supervisory process, placing crypto custody inside an existing supervisory channel rather than a standalone crypto-licensing system.

Minnesota has taken two very different crypto-policy steps on the same date. The state also prohibited public virtual-currency kiosks beginning Aug. 1, as Daily Crypto Briefs reported in its coverage of the Minnesota crypto ATM ban. One measure shuts a cash-to-crypto channel that officials linked to scams; the other permits institutions to build a more controlled custody service.

The 60-Day Notice Is the Real Launch Clock

The advance-notice requirement is the immediate operational filter. A bank or credit union must describe the service it plans to offer and the framework it will use to manage it. The statutory checklist names cybersecurity and business continuity alongside more familiar financial-institution controls, acknowledging that private-key security and access recovery are core custody risks.

The House Research summary also says an institution may use a qualified third-party service provider to facilitate custody, while retaining oversight and responsibility for compliance. That leaves room for a Minnesota institution to use specialist wallet infrastructure or a subcustodian rather than build every part of the technology stack internally.

Customer assets and associated control mechanisms must be structured to remain legally and operationally separate from the institution’s own assets, according to Chapter 93. That is a guardrail aimed at the basic custody question: who controls the keys, and what happens to a customer’s claim if the custodian encounters financial stress?

It is not a federal charter and it is not a federal safe harbor. The statute expressly preserves applicable state and federal law. That distinction is relevant as federally supervised firms pursue their own custody paths, including Circle’s OCC-approved national trust bank, which Circle said will initially provide fiduciary digital-asset custody for the company and its affiliates.

What Minnesota Customers Should Watch Next

The first signal of adoption will be named institutions, service terms and filings, not the effective date alone. The public legislative material does not say which banks or credit unions have filed a 60-day notice, how many applications Commerce has received or what assets any eventual service will support.

Potential customers should distinguish custody from an exchange account. The statute permits safekeeping and management, while trading access, lending, staking, token selection, insurance coverage, withdrawal controls and fees depend on the provider and other applicable rules. Minnesota’s law does not settle those product details.

The wider policy question is whether regulated custody can make crypto access more familiar without blurring responsibility for key security and customer protection. Our guide to U.S. crypto regulation and DeFi policy explains why the line between software, an intermediary and a custodian remains central to the U.S. regulatory debate.

Crypto sentiment was cautious as the law took effect. Alternative.me’s Crypto Fear and Greed Index read 27, or Fear, on Aug. 1.

The next check is whether Commerce or an individual institution confirms a completed notice and a product launch. Until then, the confirmed development is the legal pathway: Minnesota banks and credit unions may offer nonfiduciary crypto custody, but the 60-day notice and control requirements determine who can actually start.
