Kreechures holds the distinction of being the first NFT project to launch on the Solana blockchain. These crypto-collectibles are described as alien NFTs that have arrived on Earth in need of a home. They are generative, on-chain NFTs stored on the Solana blockchain. The initial minting on March 26, 2021, happened before the existence of widely used Solana NFT infrastructure like Metaplex's Candy Machine and the Phantom wallet, making it a pioneering project in the ecosystem. The earliest Kreechures were generated on a schedule of approximately every 15 minutes. Originally planned as a larger collection, the max supply was later adjusted to 5,000, which are separated into two decks.
