Any two CryptoKitties can mate, and a genetic algorithm creates a child with its own special traits. Every single CryptoKitty is distinct and has a digital genome that is kept in a smart contract. Initially, the purpose of CryptoKitties was to investigate the idea of virtual scarcity by utilizing smart contracts and ERC721 tokens. ERC721 made it possible to create one-of-a-kind, non-fungible tokens. This changed with the introduction of ERC721. Tokens on blockchains were previously fungible, or interchangeable each Bitcoin or Ethereum token is the same as every other. How does Cryptokitties work?ĬryptoKitties are non-fungible tokens that were initially created on the Ethereum blockchain using the ERC721 token standard. Since its debut in 2017, CryptoKittes has been one of the most popular NFT games in the blockchain industry, with over $12 million in circulation. In fact, many players have made headlines by raking in sizable sums of cash from the simple act of selling kittens in-game. This suggests that if you are a legitimate owner of a kitten, no one else will be able to claim it any longer. However, each in-game NFT cat has a unique feature that cannot be copied or destroyed. This is the most common way to make money in the game.įor example, in December 2017 a Cryptokitty has been sold for $100,000.This game is built around the idea of digital scarcity.

Breed Kitties: When you breed your Kitties together and make offspring, you can sell either the parents or the offspring.You’ll get the majority of the payment, but every transaction made in Cryptokitties takes 3.75% of the sale for itself. Having your kitty placed as a Sire in the game is another way to earn money. Sire Kitties: Kitties don’t have gender.Purchase and Sell: You can buy kitties, and then turn around and re-sell them for a higher amount, especially if you have a cat with positive traits.You can use the kitty calculator to understand good kitty-traits thats sell for more on the market. To do it the right way, you’ll want to understand what would be good breeding patterns. Otherwise, you can choose one of your kitties to breed with another player’s Sires. To start breeding, simply choose one of your existing kitties to be the Sire (this would be the daddy kitty), then select one of your other kitties to be the Dame (the mother). Once you have your first one, you’re ready to start making money, mainly through breeding.
