I used to think self-custody was done once the seed was safe. It’s not. A seed can survive and the setup can still die with you. Passphrase forgotten. Descriptor missing. Device unlabeled. Heirs panicking. Wrong helper trusted. That gap is what SPC is for. Not custody. Not seed storage. Just continuity. Seed phrase = access. Companion = continuity. 21k sats. DM to get yours.
