⚠️ NOTICE: Deployment Testing in Progress We have recently deployed a major platform update and are currently performing post-deployment testing and validation. Please do not use this website or submit any transactions until testing is complete. Some features may be unavailable or behave unexpectedly. Thank you for your patience as we work to ensure everything is functioning correctly.

Fees
Stamping is the only thing Proof charges for. Where the fee goes and how to pay it.
What is free and what is not
- Creating and publishing a proof
- Free.
- Signing in and signing a proof
- Free. No coins move.
- Viewing and checking a proof
- Free, for anyone.
- Saving a proof to the blockchain
- The stamp fee, paid in DGB, once per proof.
The stamp fee
The stamp fee is set by whoever runs this site, and can change. The amount that applies to your proof is the one shown with your proof’s payment address, under Blockchain stamp on your proof’s page. It is fixed for that proof once the address is given.
On this site the stamp fee is currently 250 DGB per proof.
10% of the stamp fees is passed on to the DigiAsset pool, as the original Proof did.
The fee is paid once per proof. If a batch’s transaction does not go out and its proofs go back to the queue, the fee already paid still counts. See If a stamp is slow.
Paying the right amount
- Send at least the amount shown to the payment address shown for this proof. Every proof has its own address; scan its QR code or copy it from the proof’s page.
- Check what arrives. If your wallet takes its own network fee out of the amount you enter, less than the fee may arrive. What reaches the proof’s address is added up until it covers the fee.
- One address, one proof. A payment counts only for the proof whose address it was sent to. The page notices the payment by itself; you do not need to paste a transaction ID.
- Too much: the stamp goes ahead. Nothing above the fee is paid back automatically.
The payment counts once it has one confirmation.
Wait before paying again
The network fee
Writing the stamp to the blockchain takes a DigiByte transaction, which has a small network fee of its own. DigiStamp pays it, once for the whole batch. You pay only the stamp fee, plus whatever network fee your own wallet charges to send it.
