I'm having trouble thinking of a situation in which this would matter and am curious what you're thinking about to give this more context. As is, I think the most complete answer would be to point you towards the steps for revealing an enchantment in the Supplement. They rarely matter, to the point that they're not even mentioned in the core rules, but they do exist. They are:
1. Show the enchantment
2. Counter the enchantment (only usable by effects that specifically say they can counter reveals)
3. Pay Costs
4. Resolve the effect
When you are unable to pay the cost in step 3, the reveal is canceled and the card is discarded. I believe this would prevent any effects contingent on the reveal occurring.
