How can words restore a wallet?
A seed phrase, also called a recovery phrase, is an ordered set of words created under a particular backup standard. A compatible wallet can use it to reconstruct key material. Cryptocurrency records remain on the blockchain; a backup plate holds recovery information.
A correct backup can help when a device is lost or damaged. Recovery also depends on the backup format, any passphrase and the wallet settings used.
Seed phrase, private key or password?
- Seed phrase
- Recovery information used to reconstruct wallet keys. Word order matters.
- Private key
- A secret used to authorize transactions. A wallet can derive multiple private keys from one backup under its derivation rules.
- PIN or app password
- Usually unlocks a device or application. It is not a substitute for a wallet backup.
- Passphrase
- If enabled, the exact same passphrase is needed for recovery. The words alone may not open the original wallet.
BIP39 and 12 or 24 words
BIP39 is one mnemonic backup standard. Plate B supports 12 or 24 English BIP39 words; these are not the only lengths or formats used by cryptocurrency wallets.
The English BIP39 list contains 2,048 words distinguishable by their first four letters. Preserve word order and record all letters of a three-letter word. Never create a wallet by choosing your own memorable words.
Choosing a seed phrase plate
A seed phrase plate, also called a metal recovery backup, records recovery information on a physical material. Check format and word count first, then marking method, readability, material, thickness and storage.
Plate B uses 316L stainless steel and a solid 3 mm construction. Punch marks form the record without loose letter tiles. Accurate marking and access control remain essential.
Explore specifications and kit contents, or compare paper, metal and digital backups.
Three checks before storage
- Verify every word, its position and each permanent mark.
- Check the backup using your wallet maker’s official safe process, never an unfamiliar website.
- Plan secure storage for the backup and any necessary passphrase or recovery settings. Do not photograph, email or upload the words.
A metal backup does not encrypt its contents. Physical durability and access control need separate attention.
