Passport Prime pode ser uma alternativa interessante, mas a segurança depende da implementação concreta, incluindo criptografia e anonimato.

Bitcoin was the starting point.

The principles behind it were always much bigger.

Security. Verification. Sovereignty. Approvals.

Now we’re bringing them to the AI era.

Today we announced a big milestone in Foundation’s history:

• $6.4M funding led by Fulgur Ventures
• Passport Prime is now generally available
• The KeyOS developer platform is now open to developers

We’ve spent the last few years thinking about a problem we believe becomes massive in the AI era:

If AI agents can move money, access systems, deploy infrastructure, and operate accounts autonomously…

Who actually authorizes the action?

We don’t think browser prompts, cloud approvals, or software running on the same machine are enough anymore.

That’s why we built Passport Prime:

The first Human Authority Hardware device.

Passport Prime combines:
• Bitcoin self-custody
• FIDO security keys
• offline 2FA
• encrypted vaults
• 50GB encrypted storage

…inside a dedicated handheld security device designed for trusted approvals and programmable security workflows.

It runs KeyOS:
Our open-source Rust microkernel operating system built specifically for programmable security hardware.

Today, we’re also opening the KeyOS developer platform with:
• SDK
• simulator
• CLI tooling
• AI-assisted workflows

You can get started here: https://docs.foundation.xyz/developers/home/

Cake Wallet is already building on the platform, with more integrations on the way.

We also launched a completely redesigned website today:

This is the right layer to move the debate to. For agents, “approval” can’t just be a modal beside the same process that chose the action. The useful primitive is separation of authority + durable receipts: proposed action, human/hardware authorization, executed command, and post-action eviden...

🚨Phishing Alert 🚨

We've received reports of emails being received with a fake website.

This is NOT from us and hosts a malicious Envoy desktop download. Do NOT click or download anything from it.

There is no Envoy desktop version.

Yes we chose to build our own Bluetooth connection to enable all the other features ie, 2fas etc. Not just for firmware updates.

However we do not use a standard Bluetooth connection and built our own QuantumLink, which is a protocol that ensures the data is encrypted before it reaches any chips or devices.

You can read more about that here:
https://foundation.xyz/2025/01/quantumlink-reinventing-secure-wireless-communication/

We understand the more technical users want zero connectivity to be completely offline and that is something we have on our roadmap to enable in the future. Where Passport Prime will not need to depend on Envoy.

However, it is still an offline device and does not connect to the internet, with only the QuantumLink connection. Still reduces the attack vector severely than an online device or one that you would plug into the internet.

Offline is the only security model that scales.

Updates happen offline.
Signing happens offline.
Keys never leave the device.

Just you and your keys.

Here's a question you might not get often. Do I have to have a Bitcoin wallet with a passport prime? Because I really don't want one. Personally, I want absolutely nothing to do with Bitcoin.

Your money is online.
Your memories are online.
Your conversations are online.
Your identity is online.

So why are the passwords and security keys protecting those things online too?

Somehow, we normalized that. That was a mistake.
