A LN node is required in this case. One could ideally practice with Polar. Then, when comfortable enough, install in an existing node @Alby Hub to manage multiple HODL invoices.

Not ideal for routing nodes though because Hold Invoices can take up significant transaction space, even those involving small amounts, and the Lightning protocol allows 483 concurrent HTLCs to conform with the standard transaction size.

Without an LN node, one could also use Robosats coordinators as escrow service, but both parties must already trust each other and sync to not allow others to take the offer.
