Bitcoin hardware wallet maker Foundation announced a $6.4 million funding round led by Fulgur Ventures alongside Arche Capital participation. The funding increases the company’s total capital raised to $16.5 million. At the same time, the Boston based company officially opened sales for *Passport Prime*, its flagship hardware device aimed at securing digital identities, financial assets, and AI driven workflows through dedicated hardware approval systems. > Foundation raises $6.4 million to expand from bitcoin hardware wallets into AI agent authorization > > — The Block (@TheBlockCo) [May 21, 2026](https://twitter.com/TheBlockCo/status/2057446360362672277?ref_src=twsrc%5Etfw) ## Foundation Pushes Beyond Bitcoin Wallets Foundation built its reputation through [Bitcoin hardware wallets](https://coinlaw.io/hardware-wallet-market-statistics/), but the company is now moving into a broader digital security market focused on AI agents and identity protection. According to the company, Passport Prime represents the first product in its newly introduced “**Human Authority Hardware**” category. The concept centers on ensuring that critical actions performed by AI systems still require direct approval from a real person through isolated and trusted hardware. The launch comes as AI agents increasingly gain the ability to handle tasks across financial accounts, cloud infrastructure, and enterprise systems. Foundation argues that traditional approval methods like browser prompts or smartphone notifications are no longer reliable enough when the same software environment may also host autonomous AI tools. Foundation co-founder and CEO Zach Herbert explained the company’s thinking behind the new device. Herbert said: “ Every era has its key management problem. For Bitcoin it was self custody. For the agentic era it is who actually authorizes the decisions an AI agent takes on someone’s behalf. That question cannot be answered by the same computer running the agent. It has to be answered on dedicated hardware, with a display you can trust and an operating system you can inspect. Nothing happens without your approval. Zach HerbertCo-founder and CEO – Foundation ## What Passport Prime Offers? Passport Prime combines several security functions into a single device designed to act as a central approval layer for digital activity. The device includes: - **A Bitcoin hardware wallet** - **FIDO security keys** - **Two factor authentication storage** - **A secrets vault** - **50GB of encrypted storage** The product runs on Foundation’s custom built operating system called **KeyOS**, a Rust based microkernel system developed over three years. Foundation said the operating system is fully open source and built specifically for secure authorization and encrypted communications. KeyOS also includes **QuantumLink**, a communication system that uses [post quantum cryptographic standards](https://coinlaw.io/quantum-cryptography-in-finance-statistics/) including ML KEM and ChaCha20 Poly1305 encryption through a dedicated Bluetooth chip. Foundation co-founder and CTO Ken Carpenter described the company’s long term vision for the platform. Carpenter said: “ A hardware wallet is a calculator. KeyOS is a computer. The SDK lets developers write policies that execute inside dedicated security hardware. The device stops being a box your keys sit in and becomes the trust layer for everything you do online. Ken Carpenterco-founder and CTO – Foundation ## KeyOS Developer Platform Expands Alongside the hardware launch, Foundation also expanded access to its KeyOS developer platform. Developers can now use the company’s SDK, simulator tools, documentation, and command line utilities to build applications for Passport Prime without needing physical hardware during initial testing. Foundation also confirmed plans to launch a dedicated KeyOS app store before the end of the second quarter. The company expects developers to build applications focused on Bitcoin transaction policies, enterprise authorization systems, identity verification, and AI workflow approvals. [Cake Wallet](https://coinlaw.io/cake-wallet-adds-bitcoin-lightning/) became the first outside team building on KeyOS. Foundation said additional integrations across financial services, identity systems, and AI authorization workflows are expected throughout 2026. Passport Prime is currently available through Foundation’s website starting at $349. ## CoinLaw’s Takeaway I think Foundation is trying to solve one of the biggest security questions emerging from the AI boom: who stays in control when AI agents begin acting independently online? In my experience, most people still trust browser notifications and mobile approvals without realizing those systems can easily become part of the same attack surface AI operates inside. What stands out to me is that Foundation is not simply selling another crypto wallet. The company is positioning Passport Prime as a broader trust layer for digital life. If AI agents continue gaining access to banking systems, cloud accounts, and personal data, dedicated hardware approval may eventually become as important as passwords once were.
