A seed phrase is a short list of words your wallet gives you when you first set it up. It is the key to your crypto. If you lose your phone or your app, that phrase restores everything. If someone else gets it, they can take your funds. Keep it private and offline.
Not to be confused with your wallet address, which is safe to share, your seed phrase must always stay private.
How it works
When you create a crypto wallet, it generates 12 to 24 words from a fixed list. This standard, called BIP39, turns those words into a binary seed. From that seed, your wallet can recreate every private key and address. Because it is standardized, you can restore your account in any compatible wallet by entering the words in the right order.
Seed phrase and private key
A private key unlocks one wallet address. A seed phrase can regenerate every private key in your account, unlocking the entire wallet. That is why protecting it is critical.
Setup and recovery
Setup is quick, but there is no second chance. When you install a self-custody wallet like MetaMask, Eternl, or Coinbase Wallet, it will show you the phrase once. Write it down and store it offline.
If your device is lost or wiped, reinstall a compatible wallet and enter the phrase exactly as given. For peace of mind, test your backup on a spare device with no funds to confirm you copied it correctly.
Security rules
Treat your seed phrase like treasure. Store it on paper or metal in at least two secure places. Never keep it in screenshots, emails, or cloud storage. Never share it with anyone. No exchange, support agent, or friend will ever need it. The only time to type it in is when restoring a wallet.
Common pitfalls
The biggest losses often come from simple mistakes: leaving your phrase in cloud notes or phone photos, falling for fake “airdrop” or “recovery” sites, or writing it down incorrectly. Even one wrong word can make recovery impossible.
World Mobile context
When you hold or stake WMTx in a self-custody wallet, your seed phrase is the only way to recover access. World Mobile does not store it, and neither the company nor exchanges can restore it for you.
How staking works
On Cardano, tokens are managed through the Vault, which asks you to back up a 24-word seed phrase, a passphrase, and optionally a JSON file as an extra recovery option. On Base (EVM), WMTx is locked in a smart contract that you control with your wallet keys. In both cases, your tokens never leave your custody; they are not stored by World Mobile.
This means the responsibility is entirely yours. If your device is lost, stolen, or wiped, there is no support team who can bring your tokens back. Only your seed phrase can do that.
Before you stake or move funds
- Write your seed phrase down accurately and store it offline in at least two secure places.
- Keep your passphrase and (if used) JSON backup equally safe.
- Test your backup on a spare device with no funds before trusting it with real money.
Owning WMTx gives you full control and full responsibility.
