Secret Recovery Phrase
A secret recovery phrase (also called seed phrase or mnemonic) is a human-readable sequence of 12 or 24 words generated by a wallet that encodes the master seed from which all private keys and addresses are deterministically derived.
✦ Key Insight
It is the ultimate backup and sole means of restoring full control of a non-custodial wallet. Losing it means permanent loss of funds; exposing it means total theft. For traders, secure management of this phrase is non-negotiable self-custody practice.
✕ Common Misconceptions
Storing it digitally (screenshots, cloud notes); sharing it with “support”; writing only one physical copy; never testing recovery on a spare device.
Detailed Explanation
How It Works: Generated via BIP-39 standard with high entropy. The words map to a binary seed, which is then used (via BIP-32/44) to derive hierarchical private keys. Entering the exact phrase in any compatible wallet regenerates the identical accounts and balances.
