I saw your bounties implementation, but I felt it was too tightly-bound to LNURL and gives too much credence to the code creator vs the reviewer, when the biggest costs are in the review. What do you ...
I think you misunderstood the flow. You want to 1.make sure it has been really paid, 2. make sure the solution really IS a solution and that can only be said by the owner which you, yes trust here. If its helpful a withdraw-link is generated for the PR-Creator. In the below flow you risk paying non-solutions/bs, cashu or not doesnt mind.
