Terms of use

Last updated: 6 November 2026. WondrPay is a hackathon project built for ETHGlobal Mumbai and is offered as a testnet preview. By using it you agree to these terms.

1. Testnet only

WondrPay runs on Whitechain Sepolia testnet with test USDT, which has no monetary value. Do not send real funds or rely on WondrPay for real payments.

2. Your wallet, your responsibility

Your wallet key is created and stored on your device, encrypted with your PIN or passkey. We never see it and cannot recover it. If you clear your browser data without a backup, the wallet is gone.

3. Payments are final

Blockchain payments cannot be reversed by WondrPay. A shop may refund you; refunds can only go to the paying wallet and never exceed the amount paid. Autopay payments run on the schedule you approved until completed or cancelled.

4. Merchants

Merchants are responsible for the goods and services they sell and for complying with the laws that apply to them. A World ID "verified" badge confirms a unique human runs the shop; it is not an endorsement.

5. Public data

Payment requests, receipts and subscriptions are written to Arkiv and transactions to Whitechain. Both are public. Do not put personal information in notes.

6. No warranty

The service is provided "as is", without warranties of any kind, and may change or stop at any time. To the extent permitted by law, the authors are not liable for any loss arising from its use.

7. Contact
