NFT Heroes Goes Live With Chainlink VRF on Ethereum Blockchain

In our previous announcement, we stated our intent to integrate Chainlink Verifiable Randomness Function (VRF) within our Galaxy Modificator generation process. We’re excited to announce that the integration is now live on the Ethereum mainnet! Now we can achieve complete randomness in the appearance of game elements on NTF platforms. As a result, users can enjoy fair distribution and robust security regarding the generation process.

Upgrade cards randomly appear on the NFT Heroes website and on once a week. They are a holder’s only way to increase the uniqueness of their NFT Hero, which directly affects its market value and place in the SIDUS hierarchy. As upgrade cards are rare and limited, the generation process must be smooth and fair for all players.

We selected Chainlink VRF as our go-to random number generator (RNG) solution because it allows any user to verify the integrity of the randomness upon which the Galaxy Modificator relies. By supplying cryptographic proofs, Chainlink VRF helps ensure that the randomness is generated and supplied on-chain in a tamper-proof manner, leading to provably fair and unbiased outcomes for all users. Not even our development team can tamper with the process, nor can outside users predict the results.

As an ambitious and growing project, NFT Heroes is considering expanding the use of Chainlink VRF to beyond the Galaxy Modificator appearance process. The project involves different innovative technologies that might also require a fair random number generator (RNG) solution as well as other solutions by Chainlink.

“Our team has repeatedly used Chainlink solutions and each time, the integration has been very smooth. The importance of Chainlink VRF is difficult to overestimate when it comes to the random and limited generation of Galaxy Modificators. I am glad that NFT Heroes users can be 100% sure of the transparency of this process.” — Dan Khomenko, CEO of NFT Stars.

About NFT Heroes

NFT Heroes is a project born from the new direction that NFT development is taking and is in line with growing market trends. The project resembles more of an NFT ecosystem than just a collection of NFT cards. It combines characteristics and features inherent in NFT avatar projects, DAO metaverse and yield farming. A variety of earning opportunities, from distribution of royalties to NFT staking, satisfies the NFT community’s quest for NFTs that have real value. The relatively low price of 0.055 ETH (less than $170) opens the NFT world up to the general population.

NFT Heroes is developed by NFT STARS in partnership with the NFT256 collective. NFT STARS is a multi-chain NFT marketplace that has accumulated a set of features and products to provide artists, digital art lovers, startup founders and investors with unique opportunities. NFT STARS’ unique offering to artists includes Gas-free NFT minting, the opportunity to create an AR gallery in which to host an exhibition, collaborative NFT creation and an NFT Pricing Scanner.
