I perceive that previous to taproot activation, m-of-n multisig addresses had an “n” max restrict of 20 keys. I additionally noticed the 998/999 tapscript multisig transaction that just lately brought on points with LND, so this tells me that the 20 max key restrict might now not be in play.

If that is right, how can I create a multisig handle utilizing 210 keys, and requiring 21 of them to spend?

I might like to do that utilizing nothing aside from Bitcoin Core 0.22 QT Console and a textual content editor (I exploit notepad++).

Proper now I exploit this command to create a multisig handle within the QT Console

createmultisig mKeysRequired "["pubKey1","pubKey2","pubKey3",...]"

What can be the right format to permit me to create a tapscript 21/210 multisig handle?

Thanks!
