https://en.wikipedia.org/wiki/Contract#Consideration
>Anything of value promised by one party to the other when making a contract can be treated as "consideration": for example, if A signs a contract to buy a car from B for $5,000, A's consideration is the $5,000, and B's consideration is the car.
A failure of a contract for lack of consideration would be if there’s no exchange of value contemplated, ever. For example if I made a promise to provide you a valuable service for nothing in return.
In this situation both sides agreed to exchange something of value so there’s obviously consideration.
They could make an argument that no damages have occurred and claim you have no credible allegation of being harmed, but that’s a different thing and far from automatic.
If this wasn't the case then every single financial futures contract or swap would be null and void. These contracts incur no cash flow on day one. They're merely a promise by one part to pay another based on some event in the future. If your legal theory was true, then one party could simply cancel any losses by voiding the contract as soon as the position moves against them.
