# Mnemonic Seed Phrase A mnemonic seed phrase is a human-readable representation used to derive deterministic wallet keys. In many self-custody systems, possession of the phrase is functionally equivalent to control of the wallet. ## Notebook evidence [[Scanned_20260730-2016]] contains mnemonic material on PDF pages 23 and 34–36. Every word sequence is redacted as a credential. The record retains only the wallet applications and source-page relationships. ## Security classification A seed phrase is not an ordinary resettable password. It should be classified as an asset-control key with a potentially unbounded blast radius across derived addresses and applications. ## Relationship See [[BIP-39]], [[Self-Custody Wallet]], [[Credential Management]], and [[Identity Economy]]. ## Source - [[Scanned_20260730-2016]], PDF pages 23 and 34–36.
