Multiple independent sources confirm the core claim. The Bitcoin Magazine X post (the linked source) explicitly names Governor Tim Walz and the bill, with specific vote counts. The St. Cloud Financial Credit Union LinkedIn post independently confirms Walz signed the virtual currency custody bill into law. The official Minnesota Revisor of Statutes site (HF 4188) shows the legislative text establishing virtual-currency custody for banking institutions. The Minnesota House of Representatives weekly review corroborates the bill's committee approval. Minor discrepancies in bill number (HF 2301 vs HF 4188) may reflect a companion bill or different versions, but do not undermine the core claim. The claim that Minnesota's Governor signed a law allowing banks and credit unions to offer Bitcoin custody services is well-supported.
