Best Practices for Storing Your Crypto Seed Phrase

Your seed phrase controls access to your wallets. Lose it or let someone copy it and the funds disappear. The goal is simple: keep the phrase offline, split the risk, and make sure it survives fire, flood, or theft.

Start With Paper and Keep It Strictly Offline

Write the words by hand on good-quality paper. Do not type them into any device. A single photo on your phone or a note in cloud storage creates an instant copy an attacker can reach through malware or a data breach.

Store the paper in a location that stays dry and hidden. A waterproof document bag inside a locked drawer works for most people. Avoid obvious spots like a desk or safe that a burglar would check first.

Split the Phrase Across Separate Locations

Never keep every word in one place. Divide the phrase into two or three groups and store each group in a different building. For a 24-word seed, one person might keep words 1-8 at a relative’s house and words 9-16 in a bank safety deposit box.

• Label the pieces clearly so you can reassemble them later.
• Do not store the full ordered list anywhere.
• Choose locations that are not linked on paper or online, such as a trusted family member’s home and a distant storage unit.

Use Metal When Paper Is Too Fragile

Paper fails in floods and fires. Metal plates stamped or engraved with the words survive both. Stamp each word once, then store the plates the same way you would the paper split: separate buildings, locked containers.

Test Recovery Every Six Months

Once a year is too long. Set a calendar reminder to pull out one piece of your backup and confirm you can still read it. Replace paper that shows fading or water marks immediately.

Run a small test transaction on a spare wallet with a fresh seed every few months. This confirms you understand the recovery process before you actually need it.
