Minnesota Law Enables Banks to Custody Crypto, Bans Public Kiosks to Curb Fraud
May 18, 2026
The bill received broad bipartisan support and aligns with efforts to protect consumers from scam schemes tied to digital-asset kiosks.
Regulators intend ongoing monitoring and enforcement to ensure consumer protection, asset security, and proper AML/KYC controls in custody operations.
The policy sits within a broader federal and cross-border context, as U.S. and Canadian authorities explore custody charters and tighter crypto oversight.
The statute emphasizes third-party risk management, asset segregation, and clear accounting for crypto holdings, signaling evolving supervisory expectations for custody providers.
Implementation specifics: kiosks must be removed from public access by December 31, and the August 1 effective date triggers heightened compliance for operators and financial institutions.
Industry reaction notes growing institutional interest in regulated custody, though implementation will hinge on security and governance standards.
The measure requires strict asset segregation, risk controls, and allows third-party custodians while keeping institutions fully responsible; regulators can pause unsafe activities and require notices 60 days before launch.
The law aims to curb crypto kiosk fraud by banning public access kiosks and mandating their removal by year-end, while safeguarding legitimate custody services within regulated channels.
Minnesota passed HF 3709, authorizing state-chartered banks and credit unions to custody digital assets like bitcoin, with the new framework taking effect August 1, 2026.
Industry players argue that the ban could hinder legitimate users and call for regulation rather than outright prohibition, with some urging reconsideration.
Institutions must implement robust business continuity plans to protect the financial ecosystem against disruptions.
Concerns about fraud, predatory fees, and traceability of kiosk transactions fueled support for the ban and state intervention.
