Heroes of NFT is Integrating Chainlink VRF to Help Power WarFactory Item Generation
We’re excited to announce that Heroes of NFT, a turn-based collectible trading card game with a unique play 2 earn mechanism is integrating Chainlink Verifiable Random Function (VRF) on the Avalanche blockchain. By integrating the industry-leading decentralized oracle network, we can obtain access to a tamper-proof and auditable source of randomness needed to generate random ERC1155 items that can be used in game as power-ups. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can trust the real item generation process.
Heroes of NFT redefines the trading card game concept. Players will be able to participate in a real economy. They’ll gain and spend game currency in exchange for valuable assets. Moreover those assets have utility i.e will determine the game pace. Also these assets are tradable with real value.
In order to provide fair and secure item generation, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof about the integrity of the process.
After reviewing various solutions, we selected Chainlink VRF because it’s based on cutting-edge academic research, supported by time-tested oracle infrastructure, and secured through the generation and on-chain verification of cryptographic proofs that prove the integrity of each random number supplied to smart contracts.
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 Heroes of NFT WarFactory 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. This provides our users with automated and verifiable assurances directly on-chain that WarFactory is provably fair and was not tampered with by the oracle, outside entities, or the Heroes of NFT team.
Fair and tamper proof item generation is crucial for such a game that values the game items. The effects of a possible exploitation of on-chain random generation would directly impact the economy that Heroes of NFT is building. For that we’re planning to use Chainlink VRF on our future value-critical applications.
“Authenticity and fairness are the keys that define what Chainlink VRF does and that’s what Heroes of NFT provides. “

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.
About Heroes of NFT
Heroes of Nft is a turn-based collectible trading card game. Players can battle in the arena against each other and show-off their skills with unique hero cards. Our novel Play 2 Earn mechanics will allow players to be participants of a real game economy. PvP and PvE modes are rewarded separately with mintable HRM tokens while the real prizes are distributed in the official tournaments. HON token holders will designate the game’s future thus they’ll be the real game masters. Future integration of Virtual Reality will carry the player to a new world where one will determine his own fate. Having all of these features, Heroes of NFT distinguishes itself from the others.
