@Kurt_Larsen could you share who’s doing module audits for $4k-10k 
— like @Ankit_Chiplunkar said, if the audit can be completed for less than the stated amount by a reputable auditor, those excess funds will not be paid out or will be returned. for reference, the ZK Email team was quoted $75k, and the stated amount is in line with our experience.
I think it’s great that multiple resource lock implementations are being developed, as this will ultimately benefit the Safe ecosystem. each implementation has its own idiosyncrasies and may be suited to different contexts. the more the merrier!
