What is a seed phrase?
A seed phrase is a list of 12 or 24 words that can recreate your wallet and all its keys. It's the master backup — and the master key. It's never entered into websites or shared with anyone.
What it does
From these words, your wallet can be fully restored on a new device. That power cuts both ways: anyone who has the words has your funds.
How to treat it
- Write it down offline; never store it as a photo, email, or cloud note.
- Never type it into a website or share it with 'support'.
- Anyone asking for it is attempting theft — without exception.
Seed-phrase mistakes cause the largest, most irreversible losses for newcomers. Getting this one habit right prevents most catastrophes.
The seed phrase is like the master key to a building that also rebuilds the building from scratch. You'd never tape it to the front door or hand it to a stranger claiming to be the locksmith.
- Sharing or exposing it = total, unrecoverable loss.
- Phishing sites exist purely to capture seed phrases.
- No legitimate service ever needs your seed phrase.
