Nunchuk.io / Nunchuk walletNunchuk.io / Nunchuk wallet

ProsPros

  • AFAIK this is the only non-KYC multisig custodian.
  • Their app has a encrypted chat feature which can come in handy when trading BSMS or PSBT files.
  • Supports a wide range of hardware wallets.

ConsCons

  • Their desktop app is in beta but I found it to have lots of bugs.
  • Linux desktop app uses a very outdated libssl package that you can't install in modern distros.
  • Their mobile client does not work with hardware wallets like the ledger nano s plus.

UnchainedUnchained

ProsPros

  • Does not cost anything for the basic model until you actually need to use them as a signer.

ConsCons

  • Does not support seedsigner
  • KYC Required.

CasaCasa

This is the one I have the least hands-on experience with.

ConsCons

  • The most basic model costs money even if you never use them as a signer.
  • They now support Ethereum ( might be a pro for some ).

DIY methodDIY method

If you have a friend who uses bitcoin you can create a 2/3 multisig and use their signature as one of the sigs.

ProsPros

  • If you use your friends sig that they use for themselves they have an incentive to keep it safe/backed up.
  • non-KYC.

ConsCons

  • If you give the descriptor to your friend, or a BSMS, your friend can see how many sats you have.
  • Probably more likely your friend looses their signing device/backup than a company loosing theirs.

Nunchuck is the solution for me. Pricing is also attractive.

I'd love to use Nunchuck with my brother and trusted friend as signers in case something happens to me and my keys. My wife could then reach out to one of them and they'd be able to sign together to get the 2 needed keys.

Only issue that I'm trying to work out is if there is a way to allow my brother and trusted friend to be part of the multi-sig but otherwise not be able to watch the balance.

Anyone know if this is possible?

You can kind of do this already with 1 of your friends. Here is a rough idea of how you would do it:

  • Have your friend send you their multsig xpub and derivation path for their signing device.
  • Create a 2/3 multisig and use their xpub + derivation path as one of the sigs in the multisig.

Your friend wouldn't be able to see your wallet since they don't have the other 2 xpubs + derivation paths, but if they needed to sign a tx they could.

Downside to this is your wife would need 1 of the sigs to get your Bitcoin. You could do a 2/3 and have your friend and brother be signers but they technically could get together and steal your Bitcoin.

Unchained is ideal for passing your wallet on to a loved one if you pass, from my understanding
