Foundation has raised $6.4 million in a funding spherical led by Fulgur Ventures because it launches Passport Prime, a brand new {hardware} gadget designed to safe digital actions in an period of AI-driven automation.
The Boston-based firm mentioned the spherical included participation from Arche Capital and brings its whole funding to $16.5 million, in keeping with a be aware shared with Bitcoin Journal.
The capital will help enlargement past Bitcoin self-custody into id administration, multi-factor authentication, and authorization methods for AI brokers.
Passport Prime, which started transport to pre-order clients in March 2026, is now accessible for basic buy. Foundation describes the product as the primary instance of “Human Authority Hardware,” a class of gadgets meant to make sure that vital digital actions require direct human approval by remoted, safe {hardware}.
The launch displays a shift in safety issues as AI brokers achieve the power to execute duties throughout monetary accounts, cloud methods, and enterprise instruments. Foundation argues that current approval strategies — similar to browser prompts or cell notifications — can not function trusted checkpoints when the identical surroundings could host autonomous software program.
Chief govt Zach Herbert mentioned the rise of AI brokers creates a brand new type of key administration problem. He argued that authorization should transfer to unbiased {hardware} with a verifiable show and working system, moderately than stay inside software program environments that may be compromised.
Passport Prime particulars
