Monero multisig is surprisingly complex. You can get an idea if you read the manual for the system I implemented to make it a bit easier to handle, here: https://www.getmonero.org/resources/user-guides/multisig-messaging-system.html

None of the "consumer friendly" Monero wallets that you could pair with supports multisig. Not Cake Wallet, nor Monerujo; the Monero project CLI wallet is currently the only wallet that offers full support.

IMHO this is most probably out of reach for this project.

I opened this issue to shill how monero-serai offers a O(n) 2-round multisig, and note how difficult integrating wallet2's implementation or writing a unique implementation would be. Seems like rbrunner already did the latter for me :sweat_smile:
