New Hampshire signs Blockchain and Self-Custody Bill HB639
New Hampshire has formally signed Bill HB639, a law on blockchain and self-custody of digital assets that aims to establish rules for the holding and use of digital assets within the state. The bill has been included in the list of legislation that the governor's office has confirmed signature.
Signature information has been recorded in New Hampshire's official legislative files, and the full text of the bill can be checked through the state's bill status system. The governor's office listed the bill separately in the announcement, confirming that it has come into effect as one of a number of bills to be signed.
HB639 is defined as a blockchain and self-custody bill that falls within the scope of New Hampshire's ongoing work in the area of digital asset policy. (Relevant reports have been hidden)
HB639's core content on blockchain and self-trusteeship
The specific content of the law has been clarified in the text of the bill, which itself is an authoritative source for interpreting the effectiveness of the bill. Readers who need precise legal texts should consult the state's bill records rather than relying on second-hand summaries.
The core of the bill targets self-custody, in which individuals directly hold their own digital assets and use their own private keys, rather than relying on a third-party custodian or exchange to keep the assets on their behalf.
Since the verified records are only legislative texts and signed notices from state governments, the description of the bill here is limited to this framework and does not mention other additional terms that are not confirmed by existing records.
Current significance of HB639 signing
For cryptocurrency users and self-custody advocates in New Hampshire, a signed bill involving blockchain and self-custody provides legal clarity at the state level and clarifies how the behavior will be handled under state law.
The move continues New Hampshire's model of directly responding to digital asset issues. The state had previously proposed a $100 million bitcoin bond proposal, but ultimately failed to pass the vote, and then decided to terminate the bitcoin municipal bond program. In the early stages of the municipal bond process, the program received a Ba2 rating from Moody's, highlighting how far the state has gone in testing crypto-related policy concepts. In this context, HB 639 became a formally signed law rather than a proposal on hold.
Relevant signing reports link it to New Hampshire's broader blockchain stance (according to media reports). The immediate significance lies in regulatory positioning: the state has moved a blockchain and self-custody bill from proposal to law.
The state's actions are also in the midst of a broader wave of state crypto legislation, including efforts from other regions, such as Rhode Island's bill to exempt small bitcoin transactions from taxes. HB 639 is New Hampshire's contribution to this state-by-state policy landscape.
