Have been all about self custody for a few years now but guess it’s time to take it to the next level. With the #[1] tutorial hopefully it won’t be too complicated for a dumb doc like me to set up!

Cold card is easy.

Recommended steps:

Make a wallet. Write down seed phrase.

Stamp it into either washers or a fire resistant plate.

Put about 1000 SATs into the wallet.

Reset the cold card.

Restore the cold card with the seed phrases.

Download sparrow wallet.

Export the read only json xpub.

Load into sparrow.

Confirm the 1000 SATs are there.... Great. You tested the backup.

Add a passphrase.

Export json xpub into sparrow as a read only wallet.

Restart cold card.

Send 1000 SATs to the wallet with the pass phrase using the airgap feature in the cols card via micro SD.

If all goes well. Load up your passphrase wallet.

Enjoy

Play aroundwithh your cold card

.Be sure to do one transaction a month just to remember how to use it.

Be sure to set a distress pin or this could just be the normal wallet if you like. Keep between $500 and $1000 there for a $12 wrench attack.

The rest of your stack should be behind your passphrase wallet. It would be smart to have 1 passphrase wallet per bitcoin and during low fee times break up your utxo into .25 increments at different addresses. Never reuse an address. Hide the seed phrase, and passphrase seperatly

Have the locations of your recovery options in your will, as well as instructions on recovery for your beneficiaries.

If your stack gets larger than 1 btc, look into multisig with passphrases.
