@Mx12art Keeper is smooth; the main features work flawlessly for a multisignature wallet with Sparrow. I tested it on the testnet (by the way, you request test SATs and they arrive immediately). Then I sent and received on the mainnet. I'm checking out the multi-user feature; it would be very useful to be able to match users quickly. When you start the wallet, it takes a few seconds to sync and shows you some tips, which isn't bad. Overall, I like it, but I'm still exploring. Its user experience feels more professional than other wallets, even though it's still a hot wallet.
