That is indeed an interesting product:
the policy would cover losses for retailers that accept bitcoin in the event that a customer transaction doesn't go through due to technical problems
That seems to be aimed to the blockchain congestion problem - it has some similarities to the service
BTC.com offers here.
However, I don't fully understand how the product works. If the purchase transaction does not go through and the money gets returned to the sender, then the merchant
should have no obligation to send his product to the buyer. But in all other cases the transaction should go through eventually - and then only in the case of a Bitcoin price crash there would be some "loss" for the merchant.
So some more details about these products would be appreciated.
