Yes, you get me right, I just wanted to point that onchain is not the "spender" as many would think. It can be called whatever "keys..."

I usually call it - the 3 levels of stash:

• onchain cold storage - your central bank, your vault, you almost never touch it
• onchain cache - your commercial bank, where you do coin control, funds management (in/out to other levels), you node (public routing or not), uncle Jim bank if you like
• LN channels / wallets - your spending pockets, just enough funds for daily, weekly spend, in multiple LN wallets

All is explained in my guides, like this ones:
