For 3-of-5 I'd sub the second "Safe at home" for "Safe at workplace or secondary residence. Obviously, not everyone has a secure work environment and/or secondary residence, but keep 2 seeds at home somewhat defeats the purpose of having a larger quorum (just stick with 2-of-3).

| #3 | Bank or trusted friend/family | Bank or trusted friend/family |
| #4 | - | Bank or trusted friend/family |
| #5 | - | Bank or trusted friend/family |

I think by wallet this section means "hardware wallet"?

- With each wallet, include the following:
- the wallet's seed, on paper or metal
- all the wallets' master public keys[^1] (xpub), on paper

I didn't know markdown supported footnotes, neat! I think it's probably still better to include the link/disclaimer inline though.

- in a storage medium (i.e. SD card, thumb drive):
- current version of bitcoin core (all platforms)
- current version of Specter Desktop (all platforms)

While backups of the software is nice-to-have, I don't think it's strictly necessary.

This was a bigger problem in the past when people used non-standard wallets, but p2wsh with output descriptors will be supported forever by many platforms (Nunchuk, Sparrow, Blue wallet, Gordian/Noded, etc).

- in a plain text document (.txt or .md), all the wallet's master public keys again, for easier access

Specter-Desktop now has a PDF export feature for pubkey info, this could be highlighted (and added to the guide)!

- plain text document including spending instructions
- Place everything in a fireproof document bag

#### Checklist
- If storing in a bank, choose different banks, definitely different branches

Have m-1 keys in different geographies (think of a flood, evacuation, etc)

- If wallets 4 & 5 are with trusted friends/family, in the event you want your heirs to access your bitcoin, ensure that they will be able to get a hold of the wallet in a safety deposit box or at home.
- Every year or two, check your devices and seeds to ensure they are still intact. Put this on your and any trusted key holders' calendars so you do not forget. There can be floods, paper can corrode, devices can break, or bank can lose your things.
- Look years ahead. If the amount of bitcoin you have calls for it, you may want to have the seeds in safety deposit boxes or with friends/family in other cities, or possibly even other countries. Though this will make checking on them much harder, there's a certain amount of money where this becomes worth the trouble.
