The traveller was returning from a trip and was carrying a Trezor in their carry-on

Constrained

Case description

A documented 2024 case involved a US customs seizure of a hardware wallet at a border crossing. The traveller was returning from a trip and was carrying a Trezor in their carry-on luggage. Border agents seized the device during a secondary inspection. The traveller had their seed phrase at home, so the funds were not at risk—they could restore to a new device. However, the customs seizure raised questions about whether the hardware wallet could be compelled to be unlocked as a condition of entry, and what legal right the traveller had to refuse. The device was eventually returned after a two-week process, but the episode highlighted the intersection of device custody and border search law.

Outcome interpretation

Access remained possible, but only with delay, dependence, or significant difficulty.
