Vantemio Donations: how it works
Revision of 10 November 2026. Status: test network. Donations run on Base Sepolia; the main network follows an independent audit.
1. What it is
Vantemio Donations lets viewers support an author during a stream or under a video. The author shows a QR code or a link; the viewer confirms the transfer in their own wallet.
2. For viewers
- Scan the QR code or open the author's link.
- Check the author's name and payout address on the page.
- Choose the amount and token, review the network fee and confirm in your wallet.
Vantemio never asks for a recovery phrase or private key, and signing in to Passport never authorises a payment.
3. For authors
- Sign in to Passport with Google or an EVM wallet.
- Create a creator profile and set the payout wallet.
- Add your channels and share your link or QR code.
- To show alerts on stream, add the overlay page to OBS as a Browser Source.
Keep the overlay address private: it contains an access key. If it leaks, revoke it in Passport and create a new one.
4. Network and tokens
| Parameter | Value |
|---|---|
| Network | Base Sepolia (test), chainId 84532 |
| Tokens | Test ETH and test USDC |
| USDC contract (test) | 0x036CbD53842c5426634e7929541eC2318f3dCF7e |
Test tokens have no monetary value. The main network will be enabled only after the contracts and payment flow are audited.
5. Fees
| Rate | Who |
|---|---|
| 0% | Vantemio partners |
| 0.5% | Agreed high volumes |
| 1% | Standard rate for all other authors |
Network (gas) fees are separate and are paid by whoever sends the transaction. A donation goes through a splitter smart contract: in one transaction the author's share goes to their payout wallet and the platform fee goes to the platform wallet. The contract does not hold funds.
6. Privacy and safety
We store only what the service needs: the creator profile, payout address and donation history. Each author sees only their own history. Overlay keys expire and can be revoked at any time.
