Gov. Kelly Ayotte signed HB 639 into law last week, making New Hampshire one of the most explicit state-level supporters of cryptocurrency innovation. The measure — known as the Blockchain Basic Laws — offers legal protections for people and businesses that use or build on distributed-ledger technology and establishes a specialized blockchain dispute docket in the superior court.
What the law does
The bill’s provisions are aimed at clearing legal uncertainty that can arise when ownership and control of digital assets are at issue. Supporters say the law affirms the right to self-custody of digital assets, and that it will provide clearer rules for developers, miners, validators and companies building blockchain-based services.
"With Governor Ayotte's signature on HB 639, New Hampshire has once again demonstrated that it intends to lead the nation in blockchain innovation," said Republican Rep. Keith Ammon, the bill's primary sponsor.
Ammon, who was a key backer of the state’s 2025 decision to authorize a strategic Bitcoin reserve, framed the bill as a second step in positioning New Hampshire as welcoming to crypto entrepreneurs and investors.
Local context and implications
The law arrives at a moment when states are taking divergent approaches to digital assets: some are tightening rules and enforcement, while others are offering legal frameworks and incentives to attract blockchain businesses. New Hampshire’s move follows its 2025 law allowing the state treasurer to invest up to 5% of public funds in Bitcoin alongside traditional stores of value such as gold and silver.
For local startups and tech firms, the new statute could reduce transactional and legal friction when disputes over wallets, smart contracts and custodial arrangements arise. For consumers, advocates say it clarifies rights around self-custody — the practice of individuals holding private keys themselves rather than relying on an exchange or third party.
- Legal clarity: Creates a framework for courts to handle blockchain-related disputes.
- Protections: Affirms individual rights to control digital assets via self-custody.
- Economic signal: Reinforces the state's earlier move to include Bitcoin in a strategic reserve.
Questions and next steps
While proponents hail the law as pro-innovation, some legal experts and consumer advocates elsewhere have warned that statutory protections must be paired with oversight and consumer safeguards, particularly given the volatile nature of crypto markets. The executive council recently blocked a separate proposal that would have allowed a state authority to support Bitcoin-backed municipal bonds, showing that not all government bodies in New Hampshire are aligned on how far to push crypto adoption.
State officials did not immediately provide an implementation timeline for the new superior-court docket or detail how judges will be trained to handle complex technical disputes. For now, the law signals New Hampshire’s intent to be a friendly jurisdiction for blockchain activity and may influence where start-ups and investors choose to locate or litigate.

| 2025 Bitcoin reserve | Allows treasurer to invest up to 5% of public funds in Bitcoin |
As New Hampshire positions itself to attract blockchain entrepreneurs, local officials and residents will watch for how these legal changes play out in practice — whether they prompt new business formation, influence investment decisions or produce disputes that test the new legal framework.
