Don't trust, verify
Are you uncertain whether the hardware wallet you received has been tampered with? Inspect the packaging, the device and install the firmware yourself before using it.
Unsure about what the firmware is doing? Check if it's open-source and verify it.
Not confident that the source code matches the firmware you installed? Verify if the build is reproducible.
Doubtful about trusting the key generation of the wallet? Generate your own entropy by rolling dice and use a passphrase.
Lack trust in the hardware wallet manufacturer or the hardware itself? Setup a multisig with wallets from different manufacturers.
Concerned that the software wallet used for multisig might be compromised? Utilize hardware wallets with screens to verify transactions and receive addresses.
Worried that the computer/mobile where you install the software wallet might contains malware that steals your private keys? Use hardware wallets that are 100% air-gapped.
Unsure which hardware wallet to buy? Take a look at our website.

Two new features to compare added to our Software Wallets comparison.
Seed Phrase Autocomplete
Some wallets support to autocomplete each seed phrase word when importing your private key. This feature increase the protection against keyloggers stealing your seed phrase, because you don't need to type the complete words.
In-app Keyboard
Some wallets render an In-app keyboard when importing a seed phrase or entering a passphrase. This feature protect the users against keyloggers stealing your seed phrase or passphrase.
