Kabosu

Österreichische Post released the Crypto stamp Kabosu on 2 May 2025, as the second character in its Comic Characters series on Crypto stamp Island. This ghost-doge debuted alongside the unicorn Aurora Sparks, joining the expanding narrative universe that would grow to include Raka, Bambu and Cassius. The edition was limited to 7,500 copies and sold for €9.90, continuing the post's pioneering work in blockchain-based philately that began in 2019.

The Kabosu character is a playful ghost-doge whose spectral design nods to internet meme culture while fitting the mystical world of Crypto stamp Island. Launched on the same day as Aurora Sparks, the pair established the thematic world-building that later Comic Characters issues would deepen. Unlike earlier Austrian crypto stamps that featured animals or abstract symbols, this series develops an interconnected narrative set on a fictional "Crypto stamp Island," with each character release adding depth to the collective story. The design approach reflects a shift toward sequential storytelling within the program, engaging collectors through both visual art and lore rather than standalone imagery alone.

Minted on the Polygon blockchain, the issue maintained the technical infrastructure Austrian Post had adopted for recent releases to reduce transaction costs and environmental impact compared to earlier Ethereum-based editions. Each of the 7,500 NFTs corresponds to a physical stamp, preserving the hybrid philatelic-digital model that has characterized the program since its inception. No contract address was publicly disclosed at launch, following a pattern seen in some recent Austrian issues where such details were provided only through specialized channels or later documentation.

Market response aligned with the established collector base for Austrian crypto stamps, though the Comic Characters series has appealed particularly to audiences interested in narrative-driven collectibles. The €9.90 price point remained consistent with recent mainstream releases, balancing accessibility for casual buyers with the limited supply that supports secondary-market activity. As one of the two launch characters in an ongoing series, Kabosu helped set the tone for the characters that would follow on Crypto stamp Island.
