Maybe something like this 1) maintainer creates a GitHub issue 2) public key created by maintainer for that issue 3) dev who wants to work on issue "claims" the issue and generates a new key, issue key + dev key (like a multi sig key) 4) cashu-address created from new key to solicit funds to do the work 5) dev does work and merges issue 6) maintainer reveals SK to dev to claim the cashu tokens.
