The Best Bitcoin-Only Hardware Wallets in 2025

‍

As Bitcoin continues to assert itself as the most robust and censorship-resistant form of money ever created, protecting your BTC has never been more important. Custodying Bitcoin isn’t just about having access; it’s about control, privacy, and long-term resilience. This is where Bitcoin-only hardware wallets come into play. Unlike multi-coin wallets, Bitcoin-only devices are designed with a singular purpose: to securely store and sign Bitcoin transactions with minimal attack surface, maximum transparency, and uncompromising sovereignty.

Why Choose a Bitcoin-Only Hardware Wallet?

Bitcoin-only wallets strip away unnecessary features and altcoin code, reducing complexity and the potential for bugs or exploits. They focus solely on Bitcoin, following the principles of minimalism, robustness, and long-term security.

Most importantly, open-source code and airgapped designs—the ability to use a device without ever connecting it to the internet—are critical to proper Bitcoin security. While some users may be used to signing transactions instantly with a USB device or mobile app, true security requires deliberate friction. Bitcoin hardware wallets that avoid Bluetooth, NFC, or Wi-Fi may feel "inconvenient," but they eliminate entire categories of potential remote exploits.

If your Bitcoin is meaningful—whether it's a life-changing amount now or it could become one in the future—it deserves Bitcoin-specific security.

Let’s now walk through the top 10 Bitcoin-only hardware wallets available today, starting from the most affordable options and climbing toward premium, airgapped powerhouses and even DIY sovereignty kits.

Entry-Level Bitcoin-Only Hardware Wallets

The Trezor Safe 3 Bitcoin-Only Edition is a strong entry-level wallet for those looking to self-custody Bitcoin without distractions. Developed by SatoshiLabs, this model offers a refined, security-conscious device tailored exclusively for Bitcoin users. By stripping away altcoin support, the firmware is leaner and less susceptible to bugs or attacks, aligning with the Bitcoin ethos of simplicity and robustness.

Key Features:

• Affordable Price: $79
