Why self-custody backups are a process, not a single seed phrase

Bitcoin self-custody is often summarized as “keep your seed safe,” but resilience has several parts:

• Backup availability: can you recover if a device is lost? • Backup confidentiality: who could learn the words, now or later? • Recovery testing: have you verified the process without exposing the seed? • Inheritance and access planning: can a trusted person understand the recovery plan without receiving the secret prematurely?
