Creating software multi-vendor multisig

[kexoni]

Hi,

I want to create multi-vendor multisig using software wallets.

Two wallets have derivation path m/84'/0'/0', but third (Electrum) have m/0'.

Sparrow will be coordinator, and while creating multisig Sparrow set derivaton path to m/48'/0'/0'/2' by default. Should I use this derivation path for all three signers (keystore), or to enter derivation path from the wallets?

The later which is m/48'/0'/0'/2  is the derivation path for native segwit P2WSH, not m/84'/0'/0.

m/84'/0'/0 is for singlesig wallet and ha s nothing to do with multisig. Their private and public keys cn not wrok with each other.

There is nothing you have to do with singlesig keys about it.
