Foundation raises $6.4m to build hardware that authorizes ai agents in real time

Overview

  • Foundation closed a $6.4 million funding round led by Fulgur Ventures and announced the news Thursday while opening Passport Prime to general sale.
  • Passport Prime is a single device that combines a Bitcoin hardware wallet, FIDO security keys, two-factor code storage, a secrets vault, and 50GB of encrypted file storage.
  • The device runs KeyOS, an open-source Rust microkernel, and ships with QuantumLink, a Bluetooth protocol that the company says uses post-quantum ML-KEM and ChaCha20-Poly1305 to keep keys and messages separate from the host system.
  • Foundation has opened KeyOS to external developers, will offer an SDK and simulator now, and plans a KeyOS app store by the end of Q2 with Cake Wallet as an early partner.
  • Company leaders frame the shift as a move from key storage to authorization infrastructure to ensure real people approve high-risk actions, but the market for agent-based authorization is still nascent so adoption and timing remain the main risks.
