The Yamaneko Yacht Club is a limited collection of 12,000 unique Japanese zodiac wildcat tokens living on the Ethereum blockchain. Colloquially known as Metaverse Birthstones, these personalized limited NFT tokens exist to celebrate human existence through Juunishi (十二支). Yamanekos are stored as ERC-721 tokens on the Ethereum blockchain and hosted on Arweave. Each Yamaneko is uniquely generated from over 277 possible traits. Yamanekos are more than just collectibles; they are symbols of personality. Each Metaverse Birthstone is meticulously crafted to reflect a birth year and has an elaborate zodiac kanji attribute that connects to one of the 12 Japanese Zodiac signs.
