Weighing Crypto Wallets: Checking for Spy Implants

After the scandal involving the discovery of spy implants in Ledger hardware wallets, users began weighing their devices.

Weight of popular models

• Ledger Nano X*: 34 g

• Ledger Nano S Plus*: 21 g

• Ledger Flex*: 58 g

• Ledger Stax*: 44 g

• Ledger Nano Gen5*: 46 g

• Trezor Safe 7*: 45 g

• Trezor Safe 5*: 23 g

• Trezor Safe 3*: 14 g

• BitBox02*: 12 g

• OneKey Pro*: 65 g

• Keystone 3 Pro*: 103 g

• SafePal S1 Pro*: 126 g

Matching the weight with factory specifications does not guarantee the absence of an implant. Attackers can compensate for the mass of a hidden device by changing other components inside the case.
