Ask HN: Any payment system integration for GitHub?

Is there any way to 'release funds' when your commit/s get merged into a specific branch.

Example of work flow:

Create milestone Link budget to the milestone Define issues Link payout to issues (% or fixed)

Once the issue is closed via commit and the commit is merged into the master branch (or the branch related to the milestone) the 'prize' is automatically released to the author/s of the commit/s.
