MyMetaverse Integrates Chainlink VRF to Power Randomly Generated Real Estate Utility in the Metaverse

We’re excited to announce that MyMetaverse—the Web3 games store for play-and-earn experiences—has integrated Chainlink Verifiable Random Function (VRF) on Polygon mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to mint our MetaBusiness real estate NFTs and ensure that the generative utility that is applied to them is fair and auditable. Ultimately this creates a more exciting and transparent user experience, as you can mint the first generative utility NFTs and use them in the Infinity Realms MMO as real estate parcels that have randomly generated business utility attached to them.

MyMetaverse’s generative MetaBusiness NFTs is now available to mint and at launch, it is integrated into three different games, including; Infinity Realms (the open-world MMORPG), Infinity Auto (the play-and-earn GTA 5 server), and Survival Infinity (the NFT-powered Minecraft server).

In Infinity Realms the MetaBusiness NFTs will be real estate plots that have varying business utility based on the randomized metadata that is generated using Chainlink VRF, in GTA 5 the NFTs will unlock a fighter jet and in Minecraft they will be usable as swords.


In order to ensure transparency and fairness in the distribution of the randomized business utility attached to each MetaBusiness NFT, 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 a time-tested oracle network, 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 MyMetaverse 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 MetaBusiness utility  is provably fair and was not tampered with by the oracle, outside entities, or the MyMetaverse team.


“Chainlink is a world leader in verifiable randomness. This kind of provable transparency is only truly possible on the blockchain and we’re proud to leverage this cutting-edge technology to provide a dependable NFT minting experience for our players.”  – Simon Kertonegoro, Founder and CEO of MyMetaverse.
