Multisig backups are a mess. The BSMS standard exists, but in my experience, the BSMS files are not compatible 100% from wallet to wallet. I’ve tried and some wallets fail to load BSMS files created by others. Period. This leaves me feeling like I would need to rely on one wallet vendor for recovery instead of the basic and universal, uncomplicated seed phrase. So for long term storage, it’s frightening to feel like you might have problems later if your chosen wallet vendor vanishes. You need to be concerned with derivation paths, key fingerprints and all that mess. My question is: has anyone simplified multisig (self-custody) backups to the fool-proof level of seed phrase simplicity? #asknostr #multisig

I was also speculating about this just yesterday. I think a possible solution is applying Shamir's Secret Sharing to the passphrase. This way you have a n-of-m access to the wallet without the derivation paths overload. I need to do some experiments.

I found https://github.com/trezor/python-shamir-mnemonic?tab=readme-ov-file

But SLIP-0039 aims to replace BIP-39, while would be nice using SSS on top of it.
