What is the Polish Crypto Stamp?
The Polish Crypto Stamp was created from a combination of a love of philately and modern technology.

Each Crypto Stamp consists of two parts: one is a traditional postage stamp, the other is represented by unique NFT tokens on the Polygon network in the ERC1155 standard, which allows multiple token types to be supported within a single application in a blockchain environment.

Therefore, the Polish Crypto system is not only a combination of traditional postage stamps and cryptographic technologies, but also a complete environment that builds a digital philatelic community in Poland and around the world.

ZicoDAO: it’s an informal association ceated by the team Dead Cryptophilatelists Society
It represents a group of passionate people who are committed to an out-of-the-box approach, both in terms of physical and digital products, hitherto developed by traditional postal institutions.
