0 / 5 completed📝 Your Master Key: Seed Phrases
Imagine losing access to thousands of dollars in Bitcoin. No password reset. No customer service. No recovery option... unless you have your seed phrase.
💡 What Is a Seed Phrase?
A seed phrase (also called a recovery phrase or mnemonic) is a list of 12-24 words that represents your wallet's master key. These words are the only way to recover your cryptocurrency if you lose your device.
🔥 The $140 Billion Problem
According to Chainalysis, ~20% of all Bitcoin (worth over $140 billion) is permanently lost because owners lost their seed phrases. Unlike banks, there's no "forgot password" button in crypto.

BIP39 includes a checksum. If you mistype one word (like "witch" → "watch"), the wallet knows something's wrong and won't accept it.
BIP39 uses a fixed wordlist of 2,048 words. Any wallet supporting BIP39 can restore your funds using the same seed phrase.
BIP39 wordlists exist in multiple languages (English, Spanish, Chinese, etc.), making crypto accessible globally.
