New Hampshire Governor Signs ‘Blockchain Basic Laws’ to Protect Crypto Users and Developers
The state establishes a specialized court docket and protects self-custody, despite a recent setback for a Bitcoin-backed municipal bond.
New Hampshire Governor Kelly Ayotte has signed HB 639 into law, establishing “The Blockchain Basic Laws act” to protect cryptocurrency users and developers within the state.
The newly enacted legislation provides legal protections for blockchain innovation and digital asset use, while also establishing a specialized blockchain dispute docket within the state’s superior court.
Representative Keith Ammon, the bill’s primary sponsor, stated that the signing of HB 639 demonstrates New Hampshire’s intention to lead the nation in blockchain innovation.
“The Blockchain Basic Laws protect one of the most fundamental rights in the digital economy—the right of individuals to control their own digital assets through self-custody,” Ammon said. He added that the law provides “clear legal protections for blockchain developers, miners, validators, entrepreneurs, and businesses building the next generation of financial technology.”
The legislative milestone builds on New Hampshire’s previous digital asset initiatives. In May 2025, Governor Ayotte signed a bill establishing a Strategic Bitcoin Reserve, making New Hampshire the first state in the nation to do so. Under that law, the state treasurer is permitted to invest up to 5% of public funds in the leading cryptocurrency, alongside precious metals such as gold and silver. At the time, Ammon described the reserve as “one little way our state could hedge against inflation in the future.”
With the passage of HB 639, Ammon declared that the state has enacted “one of the most comprehensive blockchain rights laws in the country,” signaling that “New Hampshire is open for blockchain business.”
However, the state’s push toward cryptocurrency integration has met some institutional resistance. Last week, the state’s executive council blocked a proposal that would have permitted the New Hampshire Business Finance Authority to facilitate a Bitcoin-backed municipal bond.
Understanding the Technology and Legal Framework
To help readers understand the context of this legislation, here is an overview of the key concepts and institutional roles involved:
Blockchain and Self-Custody
A blockchain is a decentralized, distributed ledger technology that securely records transactions across a network of computers. This technology enables self-custody, which refers to individuals holding their own private keys to secure digital assets directly, without relying on third-party financial intermediaries like banks or centralized exchanges.
Miners and Validators
In blockchain networks, miners and validators play a critical role in maintaining security and consensus. Miners solve complex mathematical problems to add new blocks to a proof-of-work blockchain (such as Bitcoin), while validators verify transactions and propose new blocks in proof-of-stake networks.
Municipal Bonds
A municipal bond is a debt security issued by local, county, or state government entities to finance public projects, such as infrastructure, schools, and highways. The proposed Bitcoin-backed municipal bond in New Hampshire would have represented a novel intersection of traditional public debt issuance and cryptocurrency collateral.
