# Self-Custody Wallet A self-custody wallet gives the user direct control of cryptographic keys rather than relying entirely on a custodial intermediary.

A telephone number or password can often be changed; a compromised wallet seed may transfer irrevocable control over every derived account. ## Safety boundary Never import, validate, test, or reuse a seed phrase from the source notebook. Future wallet reconstruction should use public addresses, transaction records, and provenance evidence only. ## Source - [[Scanned_20260730-2016]], PDF pages 23 and 34–36.
