What is a seed phrase? The one secret that is your wallet

Your seed phrase is your wallet. What it is, why anyone who has it has your funds, and the simple rules that keep self-custody safe.

By Mitra (@Sigmacrit) — anonymous developer of the BlazePhoenix protocol. The code is the résumé.

A seed phrase is a list of twelve or twenty-four words that mathematically generates every private key in your wallet. It is not a password you can reset; it is the wallet itself. Whoever holds the phrase holds the funds, on every chain, forever. That is the whole deal of self-custody: total control, total responsibility.

The rules that matter

Never type your seed phrase into a website, never share it, never store it in a screenshot or a cloud note. No legitimate protocol, support agent or airdrop will ever ask for it. BlazePhoenix never has custody of your funds and will never message you first or ask for a phrase; if an account claiming to be us does, it is not us. Write the words on paper, keep them offline, and treat anyone asking for them as an attacker.

Confirm the rule in practice: a swap only ever asks you to sign a transaction in your wallet, never to enter your recovery words anywhere
