New Hampshire has enacted HB 639, described as the Blockchain Basic Law, extending legal protections for crypto innovation and use in the state after Governor Kelly Ayotte signed the measure last week. The law protects individuals' rights to hold and use digital assets through self-custody and creates a blockchain-focused court mechanism, giving the sector a more defined legal pathway for resolving blockchain-related disputes. The measure adds to the state's broader effort to build a supportive framework for digital-asset activity. The move follows New Hampshire's earlier step in May 2025, when it became the first U.S. state to pass a strategic Bitcoin reserve bill allowing the state treasury to invest up to 5% of public funds in Bitcoin and precious metals. Together, the measures reinforce New Hampshire's position as one of the more crypto-friendly U.S. states while federal digital-asset regulation remains fragmented.
