Case study

Collaborators

Turns verified GitHub activity into on-chain rewards. Maintainers set bounties on open issues; contributors get paid to their wallet once the work is reviewed.

Problem. Open-source maintainers have no good way to pay the person who fixed the issue. Contributors have no durable, verifiable record of the work they did. Both sides fall back on goodwill, which doesn’t pay rent.

Approach. Tie rewards to activity that can actually be verified. Contributors log in with GitHub and link a Solana wallet; the platform tracks real contributions rather than self-reported ones. Maintainers connect a repo and set a bounty directly on an open issue, and once the work is solved and reviewed the funds go straight to the contributor’s wallet. Verified contributions also mint NFT badges, so the record outlives any one platform.

Outcome. The bounty system is live, and the project went through the Cypherpunk Hackathon powered by Colosseum. It’s the clearest example of me taking something from zero to a working product in a domain (on-chain payments) where “mostly working” isn’t good enough.
