Is your goal to receive zaps, then eventually move them into cold storage multisig?

I receive zaps to my nostr:npub15klkdfx9sh3y096a5jf895rcvkmkzvly2fm9dgxq6huqhp9576jsav4m73 node right now, then swap using nostr:npub1psm37hke2pmxzdzraqe3cjmqs28dv77da74pdx8mtn5a0vegtlas9q8970 to liquid for the medium term. Eventually I jump from liquid to my Nunchuk multisig OR my single sig coldcard.

Or do you mean a lightning wallet governed by a multisig setup? Because lightning wallets can't be cold storage themselves... they must be hot.
