What is a Mnemonic Phrase?
A mnemonic phrase (also called seed phrase or recovery phrase) is a list of words that stores all the information needed to recover a cryptocurrency wallet. It's defined by the BIP-39 standard.
How it works: Random entropy (128 bits for 12 words) is generated, then mapped to words from a standardized 2048-word list. This phrase can deterministically generate all your private keys and addresses.
Security:A 12-word phrase has 2¹²⁸ possible combinations — that's 340,282,366,920,938,463,463,374,607,431,768,211,456 possibilities. It would take billions of years to brute-force.
⚠️ Important Safety Tips:
- Write your phrase on paper and store in a secure location
- Never store digitally (no photos, no cloud, no notes app)
- Consider using a metal backup for fire/water resistance
- For large amounts, always use a hardware wallet (Ledger, Trezor)
