In security design, a tamper-evident hologram or holographic seal makes an unauthorized access to the protected object easily detectable.

Trezor One[edit]

The package of Trezor One is protected by a tamper-evident hologram seal. If the sticker is torn or damaged in any way when delivered, please contact our Support Team immediately.

Note The packaging and holographic seals have undergone some updates and facelifts over the years. To see the individual changes in the Trezor packaging, see Trezor packaging timeline.

Trezor Model T[edit]

Trezor Model T features a tamper-evident hologram, using extra strong glue as a security measure. The hologram is placed over the USB-C connector.

Anybody trying to tamper with the device needs to detach the hologram first. This will completely destroy the hologram and leave a residue. A device with a missing or destroyed hologram, or a glue residue should be deemed as tampered. In such case, please contact our Support Team.

ImportantUnlike Trezor One, there is no holographic seal on the Trezor Model T box.

If the device USB-C port is covered with a Trezor hologram and the device does not show any warnings when starting, it can be safely assumed that nobody modified the device during the transport.

Apart from the physical tamper-evident hologram, the Model T also uses software safeguards against tampering. The device firmware and bootloader are signed by SatoshiLabs, and these signatures are checked whenever you start the device. The Trezor will warn you if the signatures are invalid.
