Tbh I'm not sure. I was trying a few of the wallets from https://github.com/cashubtc/awesome-cashu?tab=readme-ov-file#wallets---nostr-nip-6061-support and was green to what I should add. I finally tried https://chorus.community and was able to deposit in some sats via the default mint on it.

Hey. NIP-60 is a wallet NIP--most NIP-60 wallets allow you to connect to any mint. On the awesome-cashu page you can find some mint discovery/ratings services. Pablo has a good explanation and links to NIP-60/61 on his NIP-60 wallet here: https://github.com/pablof7z/nutsack
