The national postal service of Switzerland is working to bridge the gap between physical stamps and the digital cryptocurrency industry by introducing tradable digital stamps. On Sept. 20, the Swiss Post officially announced the upcoming launch of the “Swiss crypto stamp,” a digital collectible linked to a physical stamp issued by the postal service worth 8.9 Swiss francs. The Swiss crypto stamp will provide a digital representation for a physical stamp and will be stored on a blockchain. “Each design forms a nonfungible token and is stored in the Polygon Blockchain,” a spokesperson for the Swiss Post told Cointelegraph.
