Key Takeaways
- Minnesota has enacted a law allowing state banks and credit unions to offer crypto custody services.
- The law takes effect on Aug. 1, 2026, and covers the safekeeping of virtual currency and private keys.
- The move comes as states write their own digital asset rules while federal crypto legislation remains unfinished.
Minnesota banks and credit unions will soon be able to hold crypto for customers, giving local financial institutions a clearer role in the digital asset market.
Gov. Tim Walz signed HF 3709 into law on May 15.
The measure, now Chapter 93 of Minnesota’s 2026 session laws, allows eligible state financial institutions to safeguard digital assets and private keys from Aug. 1, 2026.
Minnesota Opens A Bank Custody Path
The new law allows Minnesota banking institutions to provide digital asset custody as agents, bailees or trustees for limited safekeeping and administration.
It also covers control over cryptocurrencies and the private keys used to access them on a customer’s behalf.
Credit unions also gain a path to offer custody services to members, subject to state and federal law.
The bill’s core safeguard is segregation. Customer digital assets and related control mechanisms must be kept legally and operationally separate from the institution’s own assets.
Banks and credit unions may use qualified third-party providers, but they remain responsible for oversight, cybersecurity, continuity planning and compliance.
Before launching custody services, credit unions must give Minnesota’s commerce commissioner at least 60 days’ notice.
Why Minnesota Wants Local Institutions In The Market
Supporters framed the bill around trust and access.
During committee discussion earlier this year, Rep. Bernie Perryman said Minnesotans were already asking whether they could work with trusted local financial institutions to safeguard crypto assets.
That argument gives the law its political center.
Crypto custody already exists, but much of it sits with specialist platforms, national providers, fintech firms or offshore entities.
Minnesota is giving local banks and credit unions a legal route into the same function, under familiar supervisory rules.
The law may also help smaller financial institutions respond to customer demand without entering riskier parts of the market, such as trading, token issuance or lending.
Crypto ATMs Come Under Pressure
Minnesota’s custody law arrives alongside a much tougher approach to crypto kiosks.
State lawmakers advanced a ban on virtual currency ATMs and kiosks this spring amid heightened fraud concerns.
The ban is scheduled to take effect on Aug. 1, 2026, the same day the custody law becomes operative.
That timing gives Minnesota’s policy a clear shape.
Banks and credit unions are being invited into the crypto safekeeping space.
Public kiosks, which lawmakers have linked to scams targeting older residents, are being pushed out.
States Keep Moving Ahead Of Washington
Minnesota is joining a wider state push to define crypto before Congress settles on a national framework.
The National Conference of State Legislatures says at least 40 states and Puerto Rico had digital asset bills introduced or pending during the 2026 session.
Those bills span custody, money transmission, consumer protection, state investment rules and crypto kiosks.
Minnesota now fits neatly into that map: give banks a custody role, keep pressure on riskier retail access points.
What Comes Next
The next test comes after Aug. 1, when eligible Minnesota institutions can begin offering custody services.
Banks and credit unions will need vendor reviews, security systems, internal controls, compliance procedures and board-level comfort before launching products.
Some institutions may wait for more federal guidance.
Others may treat custody as a cautious first step into digital assets, as the service focuses on safekeeping and private-key management.
While Washington debates a national framework, states are already deciding how crypto enters the banking system.
