Crypto Self-Custody Walkthrough

Transcript

Welcome. In this twelve-minute walkthrough, I’m going to walk through the four habits that make self-custody survivable for working families — not traders, not institutions, regular households that just want to hold their own money without losing sleep over it.

Habit number one is hardware-wallet-first. Buy a hardware wallet directly from the manufacturer — never a third-party marketplace. Set it up on-device, generate the recovery phrase on-device, verify the firmware with the manufacturer, and send a small test transaction before moving meaningful amounts. The biggest failure I see in working-family self-custody is treating the seed phrase like your house key — when it is actually more like the deed to the house.

Habit number two is offline seed phrases. Never photograph your seed phrase. Never store it in a cloud note, a password manager, or an email draft. Write it to paper or a metal seed-phrase plate, and keep at least two copies in physically separate, secure locations — a fireproof safe and a safe-deposit box is the common starting point I walk families through.

Habit number three is two-factor authentication on anything custodial. If you keep even a small balance on an exchange, an authenticator app or hardware security key is the floor — not SMS. SMS-based 2FA has been defeated by SIM swaps in real working-family casework more times than I’d like to count, so this habit is non-negotiable.

Habit number four is an annual recovery rehearsal. Practice restoring from your seed phrase on a second device where the wallet supports it. Re-test after major firmware updates. Document who in your household knows the recovery plan — including a trusted contact for estate scenarios, written down, not just in someone’s head.

That’s the walkthrough. For the printable reference, download the free one-page wallet-security checklist linked at the bottom of this page. For the broader context — why self-custody matters going into the November 2026 ISO 20022 migration — read the Sentinel explainer in the articles section. Take care, and own your keys.

Key Takeaways

• Buy a hardware wallet direct from the manufacturer

  Generate the recovery phrase on-device, verify firmware, and fund with a small test transaction before moving meaningful amounts.

• Keep the seed phrase offline and physically redundant

  Never photograph, cloud-store, or email the seed phrase — write it to a durable medium with at least two geographically separate copies.

• Use authenticator-app or hardware-key 2FA on custodial accounts

  Avoid SMS 2FA on exchanges; SIM swaps have drained working-family balances — prefer Authenticator apps or security keys.

• Rehearse a full wallet recovery once a year

  Restore from the seed phrase on a second device where supported, retest after firmware updates, and document a trusted-estate contact.
