Discussed a bit here

A core benefit is unilateral opens. I.e. you can pay someone into a
derivative without them being online.
For example, you want to receive your payment in a Bitcoin backed Magnesium
risk reversal in exchange for some phys magnesium. I can create the
contract with your signing keys offline.

I have a decent understanding of a bit of the trading world and can answer
most questions you have, or point you to someone else who would.
The way a unilateral option would work is that I can create a payment to
you paying you into an Option expiring next week that gives you the right
to purchase from me a magnesium risk reversal contract that settles next
month.
An example where this type of pattern must be used is in conjunction with
DCFMP and PowSwap where miners could commit to, instead of just keys,
'trade specs' and an Automatic market maker inside the DCFMP could attempt
to match that miner to a counterparty who wants the opposite hashrate
hedge. The need to exchange signatures would make this unviable otherwise.
