(Hardware wallet, Black)

The Passport Core Stealth by Foundation Devices is a secure, air-gapped Bitcoin hardware wallet designed to make self-custody simple, transparent, and verifiable. Built in the USA with fully open-source hardware and software, Passport combines robust security with an elegant, intuitive user experience, helping you take full control of your Bitcoin without ever trusting a third party.

The Stealth Edition features a sleek, matte-black finish and minimalist design, giving it a discreet and professional look while maintaining all the trusted features of the Passport Core. Every aspect of the device is engineered for privacy, transparency, and usability, making it a reliable companion for long-term Bitcoin storage.

Passport Core operates completely air-gapped, using QR codes and microSD cards to sign transactions, no USB, Bluetooth, or wireless connectivity required. This eliminates entire classes of remote attack vectors while keeping your private keys permanently offline. The device runs open-source firmware that can be independently audited, and its secure element is used only to store encrypted data, not to hide proprietary code.

The large high-resolution color screen, intuitive navigation buttons, and guided user interface make setup and operation straightforward even for beginners. Passport is fully compatible with leading desktop and mobile wallets such as Sparrow, Specter, Nunchuk, BlueWallet, and Zeus, allowing you to integrate it easily into your existing Bitcoin workflow.

Each Passport Core Stealth includes a replaceable lithium-ion battery, a microSD card for firmware updates and backups, and all necessary accessories. Foundation Devices prioritizes open design, verifiability, and long-term sustainability, ensuring that your Bitcoin remains safe, accessible, and under your full control.
