Svmuu reported that Bitcoin hardware wallet manufacturer Foundation announced the completion of a $6.4 million funding round, led by Fulgur Ventures with participation from Arche Capital. The total cumulative funding has now reached $16.5 million. The funds will be used to expand its business from Bitcoin self-custody hardware wallets into a broader digital security infrastructure sector, including identity verification, multi-factor authentication, and AI agent authorization. Foundation is extending the "self-custody and hardware trust model" to more complex smart agent and digital identity scenarios. (The Block)
