1. Inspect the Device Packaging
Before connecting, critically examine the anti-tamper seals and packaging integrity. The holographic seals must be unbroken and show no signs of previous opening or distress. A genuine Trezor box is factory-sealed. If there is any doubt regarding the physical security of the device or its container, **do not proceed** and contact support immediately. This initial scrutiny is your primary defense against supply-chain attacks. Treat this physical confirmation as the first line of digital defense.
2. Secure Environment Requirement
Perform the entire setup process in a private, distraction-free environment. Ensure no cameras, onlookers, or screen-sharing applications are active. Your Seed Phrase is the ultimate master key, and its exposure, even momentarily, compromises all future security. Utilize a hardwired internet connection if possible, and verify that your operating system is up-to-date. This step minimizes potential vectors for malicious intrusion.
3. Connect and Verify Firmware
Connect your Trezor device to your computer using the supplied USB cable. Navigate directly to the official Trezor Suite application (or the Trezor web interface). The software will prompt you to install the latest official firmware. The device screen must display the correct Trezor logo and the corresponding fingerprint hash must match the one displayed in the Suite application. Never install firmware from unofficial or third-party sources. The integrity of the firmware guarantees the trustless operation of your hardware.
