LULU Market Integrates Chainlink VRF

LULU Market integrates Chainlink VRF to help randomize outcomes of crop harvests. LULU Market is a Web3 GameFi project that aims to develop a healthy and sustainable ecosystem. 


By integrating the industry-leading decentralized oracle network, LULU now has access to a tamper-proof and auditable source of randomness needed to determine in-game outcomes in a fair manner. Ultimately this creates a more exciting and transparent user experience. Users can verify that the outcome of each crop harvest is fair to all players.

Through play-to-earn gaming and NFT minting in LULU Market, players can participate in DAO governance and receive staking rewards. They also support its in-game economy by bridging its platform to the blockchain and the real world, even enabling players to purchase physical goods from LULU Market.


In order to generate random in-game outcomes, LULU needs 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 derives from blockchain data like block hashes. It can be exploit by miners or validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof of the integrity of the process.

Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-commits private key to generate both a random number and a cryptographic proof.

The LULU Market smart contract will accept the random number input if it has a valid cryptographic proof, and the cryptographic proof that generates if the VRF process is tamper-proof. This provides its users with automation and verifiable assurances directly on-chain that the planting mechanism is provably fair and is not tamper with by the oracle, outside entities, or the LULU Market team.

Web 3.0 is built upon the core concepts of openness and greater user utility. As we aim to be a fair and transparent GameFi project, LULU Market is thrilled to integrate Chainlink’s industry-leading technology that supports advanced smart contracts on any chain. Using Chainlink VRF helps generate fair and transparent in-game outcomes for our users.” — Zac, Director of LULU Market.
