Application issue: Grant Application - Shielded Zcash Payments in KOKOPAI · Issue #556 · ZcashCommunityGrants/zcashcommunitygrants · GitHub
Summary. Integrating shielded Zcash as a payment system in KOKOPAI, an AI-created video platform with a marketplace for digital collectibles. Users add credits by paying shielded ZEC from their own wallet, and spend the credits in the marketplace.
Requested: USD 14,500 · Category: Integration · Startup funding: none
How it works. Everything on KOKOPAI is priced in acredits. On the Add credits page a user picks an amount, chooses Zcash and scans a ZIP-321 QR. KOKOPAI’s server detects the payment with a viewing key, verifies amount, memo, expiry and confirmations, and adds the credits. No Zcash spending key is on the server and no Zcash key is in the browser.
Milestones
| # | Deliverable | USD | Date |
|---|---|---|---|
| 1 | Zcash payment core on testnet: quote, ZIP-321, verification, example app, CI with a real testnet payment | 4,950 | 2027-01-15 |

| 4 | Three months of maintenance and a usage report | 1,650 | 2027-05-28 |
Open source. KOKOPAI’s repository is private, so the Zcash payment module is published separately under MIT, with tests and an example app.
About me. I built zcash-faucet and zcash-testnet-wallet (both MIT, on npm) and have open PRs on zcash-devtool and sapling-crypto. Everything is listed at GitHub - anukulpandey/zcash-pow: Proof of work: my Zcash tools, contributions and posts, with links · GitHub .
Disclosures. I am applying as an individual. I build and run KOKOPAI, which benefits from this integration. KOKOPAI is pre-launch, so there is nothing public to try yet and I am not claiming users. KOKOPAI has no outside funding. I also have a USD 1,500 retroactive application pending in the Q4 coinholder round for the faucet and testnet wallet, which is separate, finished work. The attached images are design mockups of proposed work, not a working feature. I used an AI assistant to help draft and edit this application; the design, the scope and the commitments are mine.
I’ll post monthly updates in this thread and answer questions here.
