CTV and Cold Channels.

Today in Bitcoin, to make a channel, you must first receive Bitcoin on-chain and then transfer it to a channel with your partner interactively. This is a minimum of two transactions just to open a channel and the channel opening cannot be batched.

With CTV, channels can be hidden inside your pubKey so that when you're paid and the transaction is committed on-chain (can even be batched using only one UTXO), that on-chain commitment is sufficient to use your channel. No need to dump the channel details on-chain.

It should look like a relatively normal channel except you roll it up into ctv to hide it. It is "cold" since you partner isn't aware of its existence yet. You'll need to coordinate with them to close it efficiently, otherwise you'll have to deal with the time locks.
