If you don't have a multisig or social recovery wallet, imo the next best is to split up your seedphrase with a "poor man's 2-of-3": chunk 1 is top + middle, chunk 2 is middle + bottom, chunk 3 is bottom + top. We could even use the kind of paper that people use to sign two copies of a form at the same time for this:

Followup: actually you should do this with 24-word seeds and not 12-word, so that there is enough remaining entropy to make the wallet secure even if one of the chunks gets stolen.

I feel like the easiest thing someone can do to increase EOA security is keep some decoy ETH in the default path and hide real value behind a BIP39 passphrase. Not sure why this is almost never talked about

Any one of the pages only has 4 of words missing. Is that brute forceable? I remember reading about some impressive brainwallet cracks years ago…

I just store entropy and memorise the salt For those who wonder BIP39 explained https://m.youtube.com/watch?v=rA3BFzq7FOk

I don't think most people actually know what it means to truly "own" something and the difficulty that comes with protecting that in which they find significantly valuable. I had to become a minimalist in order to discover I didn't own my things, they owned me

Protip: Don't use paper. I tried a variant of this with 5 friends, and 3 of them lost the paper within a few years (moves, etc). My next attempt will be requiring people to save it in their password manager.

Yes, good suggestion For anyone interested, there are other similar examples in @christophera's smartcustody.com book If you'd like to sponsor/donate to the new edition, you can support here https://github.com/sponsors/ChristopherA

I split them in 4 such that I can recover them if I have any of 3 pieces.

Love the simplicity of this method! However if you do this for 12 word seed you only need to brute force about 33 bits of entropy to crack the seed from one of the shards. IMO this method is one of the main use cases for a 24 or 36 word seed. For a 36 word seed each shard needs around 128 bits of entropy to crack.

There is also this: https://iancoleman.io/shamir39/ But it's not that simple as pen and paper method you described.

I gave half of them to my mom who is on the other side of the country, and call her everytime I need them.
