Maintainers can and are encouraged to specify the entity of the prospective reward in the issue (see examples here https://github.com/slice-so/merge-to-earn/issues).

However this should be limited to maintainers as rewards in merge to earn are related to actual ownership of the project and its future earnings.

But anyone could open an issue, and then the maintainer can add a tag to it depending on the reward it thinks it could be worth.

At the end though it's important to note that the contributor opening the PR has the final word on the amount being requested for the work done.
