You could do a version of this with gator.metamask.io where it doesn't cost a tx fee to "stake" (extend allowance). Allowance would have to be active to be visible, and the reader gets to determine when the "race" to withdraw begins, and so achieve good safety if they have a bundler they trust.

The contracts are already public and accessible from that page. We're also refining an SDK for using it more conveniently, and inviting devs into that early beta by invitation. I'm sure we'd get you oriented if you're interested.
