What is a crypto stamp?

A crypto stamp is a stamp made up of two parts: a physical stamp and its digital twin. The digital twin is an image that you can collect, exchange and trade on the blockchain1.

Physical stamp

You can collect the physical stamp or use it to send your mail.

Digital twin

Each physical crypto stamp has a QR code that allows you to discover its digital twin. This is your own NFT2 ("non-fungible token").

Limited edition

The new Luxembourg crypto stamp is a limited edition of 15,000 copies.

The Luxembourg crypto stamp is a stamp made up of two parts: a physical stamp and its associated digital twin.

It is the twin of your physical stamp. You can use it to create your own digital collection. If you do this in the blockchain, you will need cryptocurrency and a wallet3.

The selling price of the first two crypto stamps (9.00 € each) corresponds to the former rate for sending a registered letter in size M within Luxembourg. The value of the Artemis crypto stamp (10.30 €) reflects the new rate for sending a registered letter in size M within Luxembourg (4.80 € for the postage stamp and 5.50 € for the registration fee).

Purchasing the Luxembourg crypto stamp should be done only on our website or in official outlets. The real Luxembourg crypto stamp contains an encrypted NFC chip that can be read with a smartphone. In this way, its authenticity can be verified.

Yes. Please follow the instructions on your packing slip and returns form to return your Luxembourg crypto stamp. Please note that returns will only be accepted in unopened and undamaged packaging.

Don't worry about your address details: they are submitted in encrypted form via the blockchain. You will then receive the physical stamp by post.
