The Trezor Safe 7 Charcoal Black. It features three security chips from three different vendors, an aluminum unibody, and a touchscreen that clearly displays your transactions. Plus, you can set it to bitcoin-only firmware in just a few clicks.<\/p>\n<h2>Specifications<\/h2>\n<ul class=\"bss-spec-list\">\n<li><strong>Secure elements<\/strong>: TROPIC01 (auditable) and Optiga Trust M, EAL6+ certified<\/li>\n<li><strong>Processor<\/strong>STM32U5G, ARM Cortex M33 at 160 MHz<\/li>\n<li><strong>Screen<\/strong>2.5-inch color touchscreen, 520 x 380, Gorilla Glass 3, 700 nits<\/li>\n<li><strong>Controls<\/strong>touch screen with haptic feedback<\/li>\n<li><strong>Connections<\/strong>USB-C and Bluetooth 5.0, with open source protocol<\/li>\n<li><strong>Battery<\/strong>LiFePO4, 330 mAh, wireless charging via Qi2<\/li>\n<li><strong>Housing<\/strong>anodized aluminum unibody, IP54<\/li>\n<li><strong>Dimensions<\/strong>75.4 x 44.5 x 8.3 mm<\/li>\n<li><strong>Weight<\/strong>45 grams<\/li>\n<li><strong>Backup<\/strong>: 12, 20 of 24 words, plus multi-share backup and passphrase<\/li>\n<li><strong>Firmware<\/strong>: open source, bitcoin-only, or universal<\/li>\n<li><strong>Version<\/strong>Charcoal Black<\/li>\n<\/ul>\n<h2>Three chips, three suppliers<\/h2>\n<p>The Safe 7 stores your keys behind two separate secure elements plus a hardened security processor. They do not come from the same manufacturer. That is the core of the design: a flaw or backdoor at one supplier does not leave your device exposed.<\/p>\n<p>The TROPIC01 is the most striking component in that regard. Where a secure element is normally a closed chip whose interior you have to take on faith, this one is auditable. For anyone who takes self-custody seriously, that is precisely the difference between trusting and verifying.<\/p>\n<h2>Bitcoin-only firmware in just a few clicks<\/h2>\n<p>The Safe 7 comes with universal firmware that supports hundreds of cryptocurrencies. We are a bitcoin-only store, so we\u2019ll say this right away: in Trezor Suite, you can switch it to the bitcoin-only firmware. Less code on your device, less clutter on your screen, just bitcoin.<\/p>\n<p>You will find the button in Trezor Suite under Settings, under Device, in the Firmware block. You can also make that choice immediately during the initial setup. New to self-custody? Start with the <a href=\"https:\/\/www.bitcoinstuffstore.com\/en_us\/storing-bitcoin-for-beginners\/\">An Explanation of bitcoin Storage for Beginners<\/a> and prevent the <a href=\"https:\/\/www.bitcoinstuffstore.com\/en_us\/bitcoin-self-custody-mistakes\/\">most common mistakes<\/a>.<\/p>\n<h2>Daily use without cable<\/h2>\n<p>The screen is large enough to read an address all at once, and that is no luxury. You verify your transaction on the device itself, rather than on the computer which may be compromised. Bluetooth and Qi2 wireless charging make the Safe 7 a device you take with you, instead of a little box that sits in a drawer.<\/p>\n<p>Would you like to know how this one compares to the other wallets in our collection?

In Trezor Suite, you can choose the bitcoin-only firmware during installation, or switch to it later via Settings, Device, Firmware. After that, the device will only support bitcoin.<\/div>\n<\/div>\n<div class=\"bss-faq-item\">\n<div class=\"bss-faq-question\">How many secure elements does the Trezor Safe 7 have?<\/div>\n<div class=\"bss-faq-answer\">Two: the auditable TROPIC01 and the EAL6+ certified Optiga Trust M. In addition, there is a hardened security processor, an STM32U5G. Three chips from three different suppliers.<\/div>\n<\/div>\n<div class=\"bss-faq-item\">\n<div class=\"bss-faq-question\">Isn&#x27;t Bluetooth on a hardware wallet insecure?<\/div>\n<div class=\"bss-faq-answer\">Your keys never leave the device, not even via Bluetooth. The connection runs over an encrypted, open source protocol and you confirm every transaction on the screen of the device itself. If you do not want a wireless connection, you simply use the included USB-C cable.<\/div>\n<\/div>\n<div class=\"bss-faq-item\">\n<div class=\"bss-faq-question\">What's in the box?<\/div>\n<div class=\"bss-faq-answer\">The Trezor Safe 7, a USB-C cable, two backup cards, a getting started guide, a safety guide, and stickers. For a backup that survives fire and water, we recommend a steel backup.<\/div>\n<\/div>\n<div class=\"bss-faq-item\">\n<div class=\"bss-faq-question\">How long does the battery last?<\/div>\n<div class=\"bss-faq-answer\">The Safe 7 has a 330 mAh LiFePO4 battery. That type of battery is built for many more charge cycles than a standard lithium battery. You charge it via USB-C or wirelessly via Qi2.<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The latest Trezor with two secure element chips, an aluminum unibody, Qi2 wireless charging, and a 2.5-inch touchscreen.
