Do you know haveno-reto.com ? It's a bisq fork making possible to trade #Monero in P2P for FIAT & Cryptocurrencies with 2/3 multisig wallets.
Can.I use multisig in Mondeo?
Yes you can it's activated/implemented by default on each haveno trade (one multisig per trade), it's managed by the software so you dont need to modify your setup but the wallet-cli or rino supports multisig
