Retro Cat Integrates Multiple Chainlink Services to help Mint NFTs and Automate Raffles
Retro Cat integrates multiple Chainlink services to randomize the traits and characteristics of Retro Cat NFTs, and to automate monthly raffles for Retro Cat NFT holders.
Retro Cats are 10,000 randomly generated funky bundles of love. Retro Cats feature 11 different sets of traits, including 15 breeds of cat, with hundreds of variations and characteristics including common, rare, and super rare.
To generate the random characteristics of Retro Cats, we needed access to a secure random number generator (RNG) that each user can independently verify. However, RNG solutions for smart contracts require several security considerations to prevent tampering and ensure system integrity. For example, RNG solutions derived from blockchain data such as block hashes can be exploited by miners/validators, while RNG solutions derived from off-chain APIs are opaque and do not provide users with definitive proof of process integrity.
Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. The Retro Cat smart contract will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof.
Retro Cats are available for 0.02 ETH each (plus gas fees) during our presale. Once 5,000 Retro Cats are sold, 48 ETH is going to be deposited into the community wallet that will be used to fund the monthly raffle for Retro Cat holders. Each Retro Cat NFT holder is automatically entered into the raffle, where a winner of 2 ETH is randomly selected at the end of each month.
About Chainlink
Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
