New Hampshire Governor Kelly Ayotte has signed HB 639, a law that fundamentally changes the legal landscape for digital assets in the state. The document takes effect on August 18, 2026, and provides comprehensive protection for self-custody of cryptocurrencies, blockchain node operation, mining, and staking. It is one of the most progressive laws in the United States, setting a new standard for the industry.
Key Provisions of the Law
HB 639 explicitly prohibits state and municipal authorities from restricting the use of digital assets for purchasing lawful goods and services. Special attention is given to the right to self-custody — users can hold their assets in personal wallets without any obstacles. The law also excludes the introduction of additional taxes or withholdings solely on the basis that payment was made with cryptocurrency, although standard transaction fees remain in effect.
The rights to run nodes, connect to blockchain protocols, and participate in staking are separately protected. Mining and staking with personal funds will not be considered an offer or sale of securities under state law. This is an important clarification that removes a huge layer of regulatory uncertainty for market participants.
Exemption from Licensing and Judicial Innovations
The law exempts some industry participants from the requirement to obtain a money transmitter license. Miners, node operators, and staking service providers are not liable for a specific transaction if their involvement was limited to technical validation. However, these exemptions apply only at the state level and do not override federal regulatory requirements.
HB 639 also allows the state Supreme Court to create a separate judicial proceeding for resolving blockchain disputes. This could set a precedent for the entire country: a specialized court would handle cases involving fraud, contract violations, and fiduciary duties. The first judge will be appointed by the governor with the consent of the Executive Council, and the candidate must have experience in law and technology.
Risks and Uncertainties
In the fiscal note accompanying the bill, the State Department warned of weakened oversight. The Securities Bureau will lose the ability to demand compensation for investor damages and collect fines in cases falling under the new exemptions. These powers are not transferred to another body, creating a gap in consumer protection.
The judicial system pointed out several ambiguities: the law does not explicitly explain how smart contract provisions relate to existing contract law, and which court should hear disputes over cryptocurrency trusts. According to the agency's assessment, this could increase the number of litigations.
Context and Prospects
HB 639 builds on recommendations from the cryptocurrency and digital assets commission established by former Governor Chris Sununu. Lawmakers aim to attract responsible blockchain companies to the state and reduce legal uncertainty. In May 2025, New Hampshire became the first U.S. state to allow the creation of a crypto reserve: the treasury can allocate up to 5% of certain public funds to digital assets with a market capitalization exceeding $500 billion — currently, only Bitcoin meets this criterion.
However, not all state initiatives receive support: in July 2026, the Executive Council rejected CleanSpark's $100 million bond proposal backed by Bitcoin. At the federal level, the Trump administration's initiative to create a strategic Bitcoin reserve for the U.S. has faced disagreements between departments.
My analysis: New Hampshire is consistently moving toward the status of a crypto hub, and HB 639 is a logical continuation of this strategy. However, weakened oversight and ambiguities in the judicial system could create new risks. Investors should closely monitor the development of enforcement practices, especially regarding consumer protection. In the long term, such laws will contribute to the legitimization of the industry, but short-term legal conflicts are inevitable.
