Before you begin

Useful boundaries.
No surprises.

What happens after I pay?

Confirmed payment starts your selected job. Your private order page provides the result and download access. Save your result during the 30-day access window. Routine processing is automatic; unusual payment or delivery problems may need support.

What does validation cover?

These tools check supported file structure and formatting. They do not verify factual accuracy or compliance with a particular legal, security, or industry standard. Conversion supports the structures described in the selected tool.

Does the Zcash checker move money?

No. It checks payment-request syntax. It does not access a wallet, send funds, confirm a recipient’s identity, or prove payment occurred. Never submit seeds, private keys, or viewing keys.

Can I pay with shielded ZEC?

Shielded ZEC appears as a checkout choice only when the payment service is available. Otherwise, use an available payment method shown at checkout. This is separate from the Zcash request-checking tool.

What should I upload?

Use small, non-sensitive text files. Submitted content is sent for processing; paid results are saved for 30 days. Read our privacy policy before submitting. Do not include credentials, personal records, or confidential material.

Where can I get purchase support?

Keep your private order link and order number. If payment is interrupted, check that session before starting another purchase. See our terms and purchase support page for delivery issues and refund information.
