What is a seed phrase?¶

A seed phrase is a sequence of words used to recreate or recover a cryptocurrency wallet and the keys it controls.

Avoid the dangerous assumption¶

The dangerous assumption is that it is merely a password or that finding it proves the holder created and exclusively controlled the wallet.

A seed phrase is often twelve, eighteen or twenty-four words generated when a wallet is created.

Entering it into compatible wallet software may restore access to multiple addresses and assets.

Anyone who obtains the phrase may be able to recreate the wallet elsewhere and move the funds.

It is therefore highly sensitive evidence.

A seed phrase may appear on paper, metal backup, photograph, note, password manager, cloud file, message or device.

Preserve the original context carefully.

Do not type the phrase into an online service, ordinary wallet application or investigative note system to see what it contains.

That could expose the assets, alter records or disclose the phrase to another provider.

Possession may indicate potential control, but it does not automatically prove who generated the wallet or who used it at the relevant time.

The phrase may have been shared, copied, stolen or retained after control passed to another person.

Record where it was found, what device or material contained it and what related wallet evidence was present.

Use specialist support to identify the associated wallet structure safely.

Avoid reproducing the complete phrase in reports unless essential and securely protected.

Operational takeaway¶

Preserve a seed phrase as highly sensitive recovery material and use specialist methods to link it to wallets without entering, exposing or activating it unnecessarily.
