Our team at My DeFi Pet and our patrons at KardiaChain believe that leveraging NFTs and blockchain technology to their full potential will take gaming experiences to a whole new height. Following the momentum we have created over the past few weeks, My DeFi Pet is enhancing its blockchain gaming experience by integrating oracle powerhouse Chainlink to access the VRF solution.

Chainlink VRF is a tamper-proof and verifiable random number generator (RNG), supplying smart contracts with an on-chain source of randomness that they can prove to their users is truly random. My DeFi Pet is using this randomness to power randomized breeding and distributions of DeFi Pet NFTs, leading to fair and unbiased outcomes when it comes to accessing rare traits and NFTs.

Understanding My DeFi Pet and the Role of Chainlink VRF

My DeFi Pet is the top trending NFT game in Asia as recognised by Coingecko, the top trending and most widely used game in terms of users on Binance Smart Chain, and the Winner of Top 10 Most Valuable Builder Accelerator (MVBII) Program “The Bigbang of NFTs”. My DeFi Pet always shoots for the stars by continuously implementing cutting-edge technologies to strengthen our platform. It is with our utmost appreciation to integrate a wonderful service from a blockchain giant like Chainlink to make all of our ambitions become a reality.

Our players, also known as Pet Masters, are no strangers to the game mechanics involved in raising a unique pet army. In My DeFi Pet, each pet can have eight traits, which can include a wide number of variations in the Wings, Tail, Paw, Horn, Glasses, Amulet, Aura, and Outline. Through Chainlink-powered randomized breeding, a pet acquired from an egg may or may not have all the body parts above. Additionally, DeFi pets have genes that are split into either dominant or recessive genes, resulting in different offspring based on how they are expressed. Each pet has its own strengths and weaknesses that give it varying levels of combat ability, staking APR, and even aesthetic qualities.

In technical terms, egg hatchings use random numbers as inputs that are combined with the “gene traits” and the probabilities of those gene traits being expressed to birth new pets. The total realm of possible outcomes contains over 2 million variables in appearances and stats.

Building randomness using blockchain technology helps prove the integrity of the random outcome in a transparent manner. However, randomisation mechanics, either centralized or using on-chain data, are still subjective to exploits and tampering. For example, on-chain block hashes alone can lead to minor reorg attacks and off-chain RNG data providers are opaque. Even established game publishers are struggling to deal with this problem across game genres, evidenced in major game companies such as EA — who have historically struggled with their loot box mechanics — and various gacha games (games that use randomized mechanics to offer new characters and items) in the mainstream market. This is where Chainlink VRF comes into play as an innovative approach that provides our smart contracts with provably fair and verifiable on-chain randomness.

Chainlink Verifiable Random Function (VRF) works in the following manner. For every new request for randomness, Chainlink VRF generates a random number and cryptographic proof of how that number was determined. Our smart contract only accepts the random number if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This provides users with automated and publicly verifiable assurances directly on-chain that each My DeFi Pet using Chainlink VRF for randomness is provably fair and cannot be tampered with or predicted by the oracle, outside entities, or the development team.

Simply put, by using Chainlink VRF, My DeFi Pet’s in-game results are guaranteed to be 100% random and provide reliable verification, security, and transparency. Chainlink VRF enhances My DeFi Pet by allowing high frequency rolling, and we also plan to integrate Chainlink Price Feeds to enable NFTs to be priced on-chain in various cryptocurrencies in the future, all recorded the moment the input was recorded. In our community, we have a saying that what you earn in-game through randomising is “based on your good karma”. Our integration with Chainlink VRF is a firm statement that further brings fairness to the game whenever players generate new pets with Rare or Mythical traits, bringing surprise factors and re-igniting your love for the game.

KardiaChain, My DeFi Pet’s creator, is working with Chainlink Network to enhance e-Sport incentive platforms by bringing the same values of transparency and fairness. Being passionate gamers and DeFi users at heart, we cannot be more excited to expand our platform offerings with Chainlink-powered functionality to move towards greater success in the blockchain gaming landscape.

“Chainlink VRF is a necessity in today’s blockchain games, providing our smart contracts with an unbiased source of randomness that all users can verify is tamper-proof,” stated Tri Pham, CEO of My DeFi Pets. “Ultimately, integrating Chainlink VRF will create a fairer, more transparent, and increasingly secure gaming experience for our users and set us up for long term success.”
