How to use multisig?

There is a create multisig option in Counterwallet.

How to use it? Any guide / tutorial?

Specifically, I would like a 2-2 multisig where every transaction is signed in counterwallet + another client.

There’s no graphic tutorial as far as I know. @Filip do you know?

We could certainly create one.

Check this post: I cannot create multisig address on counterwallet.io (testnet)

Can you make it work based on it?
