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 blockchain4.

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").

A first

Get your hands on Luxembourg's very first crypto stamp. This stamp is all the more special because POST Luxembourg is launching it as part of a joint issue with the Austrian and Dutch Posts.

LU crypto stamps user guide

  1. Discover the color of the digital twin

    The crypto stamp contains a locked NFC chip. Approach your smartphone to the crypto stamp. Any smartphone with an NFC function can read the chip. 
    If your smartphone is not equipped with an NFC function, please scan the QR-Code located on the back of your crypto stamp.
    Your smartphone's browser will automatically open, prompting you to enter the Code [A] on the back of the crypto stamp. After a few moments, you'll discover the associated digital twin (NFT) and its color.

  2. Create your own NFT wallet

    Use your laptop or computer to visit metamask.io (The crypto wallet for Defi, Web3 Dapps and NFTs | MetaMask) and download the MetaMask browser extension. Complete the steps to create a new wallet. If you already have one, simply import it.

  3. Connect your wallet to cryptostamp.com

    Go to cryptostamp.com/wallet and click ‘connect wallet'. Use the MetaMask extension to log in. Your wallet is now connected. The digital twin of your stamp will now appear in your cryptostamp wallet.

  4. Switch to the Polygon network

    Your digital twin will now appear. Time to switch over to the Polygon network. Your MetaMask wallet is automatically configured to use Ethereum. To change the network, click on “switch network” in the MetaMask extension.

  5. Store your digital twin in your wallet

    You have reached the final step! Scan the QR-Code [2] on the back of your crypto stamp, which is protected by a security film. Click on "Transfer stamp into your wallet", enter your personal wallet address and click on "Transfer" again. Wait for confirmation of the transaction. Congratulations! Your LU crypto stamp is now in your NFT wallet.

  6. View the NFTs in your wallet

    If you have ordered several crypto stamps, follow the steps as many times as required to register them in your NFT wallet. To view your collection, go to cryptostamp.com/wallet to view your collection.

Are you looking for this information?

The LU crypto stamp costs the same as a stamp for a registered national format M item, €9.00. So, you can use it for that too.

The Austrian crypto stamps are available online and onchain cryptostamp.com,

The Dutch crypto stamps are available online at postnl.nl

The LU crypto stamp is a stamp that consists of 2 parts: a physical stamp and a linked ‘digital twin’. It is Luxembourg’s’ first crypto stamp. And thanks to our collaboration with Austrian Post and the Dutch Post, this is also the first crypto stamp issued by three postal services together!

It is the twin of your physical stamp. You can use it to create your own digital collection. If you do this in the blockchain4, you will need cryptocurrency and a wallet.

With a Luxembourgish crypto stamp worth € 9 you have the possibility to send a letter in format M by registered delivery to Luxembourg, which costs € 4 for the stamp and € 5 for registered delivery.

We have chosen Polygon for storing and trading the digital twins. They process transactions using the so-called 'proof-of-stake' principle. This consumes a lot less energy than ‘proof-of-work’, which is what cryptocurrencies like Bitcoin use.

Purchasing the Luxembourgish crypto stamp should be done only on our website or in official outlets. The real Luxembourgish 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 LU crypto stamp. Please note: returns will only be accepted in unopened and undamaged packaging.

You can buy the crypto stamp onchain through the Austrian website. Whereas you normally order the physical stamp first, in this case you buy the digital twin first. You pay for your purchase with cryptocurrency, after which your LU crypto stamp will appear in your own wallet. After that, you can request the corresponding physical stamp within 5 years.

Customers can buy a first day cover (FDC) with the Luxembourgish crypto stamp. The Luxembourgish crypto stamp and the first day cover are only available online at postphilately.lu.

Onchain sales take place via the Austrian website. The physical LU crypto stamp can be requested via the button 'Request shipping'. 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.

No. MorphXYZ only transforms the Crypto stamp Safe, while your lion stamp remains unchanged. After the MorphXYZ transformation, you therefore have both your lion stamp and the baby lion.

To be able to create lion babies, you need to have a lion crypto stamp and an Austrian or Dutch Crypto stamp Safe. Once you have purchased them, you can combine them for free.

No. Each Crypto stamp Safe can only be used once for the Crypto stamp MorphXYZ metamorphone process. This means that a lion motif can only transform one Crypto stamp Safe.

Crypto Stamp Safe

1/ Crypto Stamp Safes are modifiers from Österreichische Post and PostNL that allow you to create new designs from your Luxembourg crypto stamps. Behind the fold-out stamp you'll find one of three magical symbols: a soother, a baby bottle or a rainbow. They can be combined with various animal motifs, including the Luxembourg lion, to create a completely new symbol. Find out more on the websites of Österreichische Post or PostNL.
