Your seed phrase is everything

Twelve or twenty-four little words are the master key to your entire wallet. Lose them, lose your coins. Here’s how to treat them right.

When you create a , it hands you a list of words, usually 12 or 24 of them. That list is your seed phrase (also called a recovery phrase). It is the single most important thing you will ever back up.

Those words are a human-readable version of your . From them, your wallet can rebuild every and every coin you control. Which means anyone else who gets them can do the same.

The two rules

  • Don’t lose it. If your phone falls in the ocean and you have your seed phrase, your coins are fine: restore on a new device, done. No phrase, no recovery. Ever.
  • Don’t leak it. Anyone with your phrase has your money. No exceptions.
Write it down. On paper. Offline.
Paper is the easy way, not the lasting oneWriting it down is the fastest backup to make, which is exactly why it’s the place to start. But paper burns, floods, fades, and tears. For a backup meant to last years, copy your words onto something disaster can’t destroy: stamping or engraving them into a steel plate is the gold standard. Do the paper copy today; upgrade to metal when you can.

Where to keep it

Pen and paper is genuinely great. Better still is stamping it into metal so fire and water can’t touch it. Store it somewhere only you know about, and consider a second copy in a separate location in case of disaster.

How you’ll get scammed (so you don’t)

No legitimate wallet, , or “support agent” will ever ask for your seed phrase. The instant anyone does, whether a website, a DM, a popup, or a phone call, it’s a scam. Close the tab.

Lost your phone? Lost your phrase?

These are two very different events, and knowing the difference removes most of the fear. Lost or broken phone, but you still have your seed phrase? You’re completely fine: install a wallet on a new device, enter the phrase, and every coin reappears. Lost the phrase but your wallet still works? Don’t panic, but act: your funds are reachable right now, so write a fresh backup immediately, then consider moving everything to a brand-new wallet whose phrase only you hold. Lost both? That’s the one with no recovery, which is exactly why the backup matters more than the device.

So make the backup bulletproof while it’s easy: more than one copy, kept in separate places, ideally stamped in metal. And actually test that you can read it back. A backup you’ve never checked is only a guess.

Never do thisDon’t screenshot it. Don’t store it in your photos, your email, your notes app, or a password manager synced to the cloud. Digital copies are exactly what attackers hunt for.

In Bad Wallet

The backup you just read about is the part the app won’t let you skip.

Your words are made on your phone and shown once, screenshots blocked. Then Bad Wallet asks for three of them back, one at a time, before it agrees you’re backed up. Skip it and your wallet keeps saying Not Verified until you finish.

The one thing to remember

Your seed phrase is the wallet. Back it up offline, never type it into a website, never photograph it.

Why nobody can guess your seed phrase

Twelve words drawn from a public list of 2,048 sounds guessable. It isn’t, and the reason is a number big enough to break your intuition. Here’s what entropy is, and what happens when a wallet gets it wrong.
