What's behind our crypto stamp?

Our crypto stamp is a post-valid stamp, i.e. you can use it for mailing like all other stamps. There is a Secure QR code (SQR code) integrated into these crypto stamps. When the SQR code is scanned with the associated app, the stamp becomes visible as a digital twin in your collection in the app. Once the crypto stamp is scanned, its digital CV starts in the blockchain. In the digital CV, events of the crypto stamp, such as a successful verification, are stored in the blockchain. These innovations make our crypto stamps forgery-proof, interactive, and exciting.

What is behind the new NFT crypto stamp?

Philately Liechtenstein's new crypto stamp not only combines the classic stamp with a digital twin in the app, but also with an NFT (non-fungible token). The NFT can be transferred to a personal digital wallet, where it can be stored or traded online. The ownership and history of this crypto stamp is digitally tamper-proof.

How does the NFT get from my stamp to my digital wallet?

Via QR code scan:

1. Scan the SQR code on the stamp using your smartphone camera or QR code reader app (not in the Stamp 4.1 app). You will now be redirected to a website that is only reserved for your crypto stamp. Important: Please do not copy and send the link to unauthorized persons.
2. Click on "GET NFT". A section with your private key and further instructions will open. Follow the steps described here. Important: The private key is a secret code that is used to authorize the transaction of the NFT to your personal digital wallet. Keep it safe and do not share it with unauthorized persons.

How can you transfer your CHLI NFT?

Transfer your NFT to your digital wallet

1. Copy the mnemonic phrase from this website. The Mnemonic Phrase is the private key for transferring the NFT. You will find the Mnemonic Phrase on your Crypto Stamp in the hidden area. The mnemonic phrase consists of 12 words.
2. Click on the ‘Swiss Post Transfer’ button.
3. If you are using a mobile device, the link should open automatically in the MetaMask app. If this is not the case, enter the URL manually in the browser of the MetaMask app.
4. If you do not have access to the MetaMask app on your mobile device, please use a desktop computer to open the link.
5. Paste the mnemonic phrase into the text field provided on the Swiss Post website. This will start the transfer process.

What can I do in the app?

Our crypto stamps app has versatile features.

All about collecting love:

• You can create a digital collection in the app. Your scanned stamp is automatically added and displayed as a digital twin.
• Check your crypto stamp for authenticity and verify your original. For this, you need a suitable smartphone with a macro lens.

What is the Crypto-Stamp-CHLI joint issue?

With the Crypto Stamps CHLI, CHLI 2.0 and CHLI 3.0, Swiss Post and Liechtenstein Post combine traditional philately with blockchain technology and digital NFTs.

CHLI marked the beginning: two stamps – one from Switzerland and one from Liechtenstein – come together to form the complete design featuring a cow, the Matterhorn and Vaduz Castle. CHLI 2.0 continued the concept as the world’s first crypto Christmas stamp edition, featuring a festive winter design. Both editions were released in six colour variants with different levels of rarity.

With CHLI 3.0, collecting becomes interactive: for the first time, a single stamp is valid for postage in both countries. At the same time, collectors can take part in the blockchain-based “Burn or Save” decision and directly influence their digital NFT.

The Crypto Stamp CHLI consists of six different colour editions. Each country has the same number of stamps per edition. The circulation per country is 12,500 crypto stamps with a total circulation of 25,000.
