How to Choose a Hardware Wallet

This guide walks through what to check before choosing a hardware wallet for self-custody. It's written for anyone comparing devices for the first time and unsure which features actually matter versus which are just marketing.

Evaluation Steps

1. Confirm the device generates and stores keys in an isolated environment that never exposes them to a connected computer or phone, even during setup.
2. Check that the device requires a physical confirmation step, such as a button press or on-device approval, before any transaction is finalized — a device that signs automatically defeats the purpose.
3. Verify the firmware or companion software is authentic by checking signatures or checksums against the manufacturer's published values before you install anything or generate keys.
4. Generate the seed phrase on the device itself, at setup time, and record it offline immediately — away from any camera, screenshot tool, or internet-connected app.
5. Test the recovery process on a spare or reset device before you start relying on the wallet for regular, day-to-day use.

What to Watch For

Skip any device or box that arrives with a pre-generated seed phrase already written down — that phrase may not be private to you, and anyone who saw it before you did could already have access. Also be cautious of setup instructions that ask you to enter your seed phrase into a website or app to “activate” or “register” the device; a legitimate device never requires that step at all.
