Seed Phrase

List of words to recover a crypto wallet.

Why it matters

Seed phrases matter because they define the practical boundary between self-custody and account-based access. Losing the phrase can mean losing recovery, while exposing it can mean losing the assets.

How it works

In practice, the wallet generates the phrase during setup, the user stores it offline or in another protected form, and the phrase is used only when restoring the wallet or migrating custody to a new device.

Risks and pitfalls

The main pitfall is entering a seed phrase into websites, support chats, screenshots, cloud notes, or wallet prompts that have not been verified. No legitimate support flow should need the phrase to troubleshoot an account.

Regional notes

In global fintech education, seed phrase should be separated from bank passwords, exchange credentials, and regulated custody records because the recovery and liability model is materially different.
