⚡️ Cha-Ching 🚀

Cha-Ching is all about engagement. Our goal is to help GitHub organizations involve builders by transforming activity into meaningful point-based rewards.

Instead of traditional bounties, organizations set their own rules for rewarding contributions such as pull requests, issues, comments, and stars. Contributors earn $CHING points (ERC-1155), redeemable or convertible into stablecoins if organizations allow it.

This makes contributing more motivating, transparent, and rewarding for developers and AI agents. Cha-Ching also provides dashboards for contributors and organizations, plus AI-powered recommendations to connect skills of developers with opportunities.

No middlemen. No spreadsheets. No manual work. Just seamless, verifiable rewards for real contributions.

🧠 How does it work

Cha-Ching turns GitHub activity into $CHING points, on-chain rewards for contributors and AI agents.

🏛️ For GitHub Organizations

1. Install the Cha-Ching GitHub App

   Choose the repositories you want to track contributions on.

2. Create a Bounty Campaign

   Define a time window (e.g., 30 days) and set custom reward rules like:

   • "Merged PR = 100 $CHING"
   • "Comment on issue = 10 $CHING"
   • "Star repo = 5 $CHING"

3. Define Reward Points & Conversion Policy

   Set how many $CHING points will be distributed during the epoch (e.g., 1,000,000 points. Optionally, describe your own redemption policy (e.g., “1,000 $CHING = $10 USDT”).

   💡 No real funds are required. The policy is informational and defined by each Org.

4. Cha-Ching Tracks Contributions Automatically

   When a contributor performs a matching action (like submitting a PR or commenting), Cha-Ching:

   • Captures the event via GitHub Webhooks
   • Signs a metadata object
   • Stores it on Filecoin via the Synapse SDK as verifiable proof

5. Distribute Rewards

   At the end of the epoch:

   • The Org can airdrop points to contributors (if authorized), or
   • Contributors can claim manually via GitHub login + WalletConnect

🧑‍💻 For Contributors

1. Contribute Freely

   Open pull requests, comment on issues, star repos — no signup or wallet needed upfront.

2. Earn $CHING Automatically

   If your activity matches an org’s rules during an active epoch, you earn $CHING points.

3. Claim Your Points

   After the epoch ends, log in with GitHub and connect your wallet to claim your rewards.

4. Use Your Points

   Depending on the org’s policy, $CHING can be:

   • Redeemed for stablecoins using a third-party solution 💸
   • Used as contributor karma 🏅
   • Showcased as part of your verifiable open-source portfolio 📜

🔐 All contributions and point awards are signed and stored on Filecoin for auditability, transparency, and decentralized verification.
