FarmHero Integrates Chainlink VRF to Secure Fair Distribution of Rare NFTs

We’re excited to announce that FarmHero — a cross chain DEFI protocol that combines yield farming, NFT and gaming — has integrated Chainlink Verifiable Random Function (VRF) on the Polygon mainnet. By integrating Chainlink’s industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to fairly distribute Rare NFTs via the FarmHero Loot Boxes. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can redeem the FarmHero Loot Boxes without worrying whether the prize is manipulated or not.

The users can earn profits while having fun on FarmHero according to their risk appetite in several different approaches.

Also, FarmHero provides several games for the community to play with each other, like the auction and fomo games.

However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions using on-chain data like block hashes can be exploited by blockchain miners, while off-chain RNG solutions like traditional data providers are opaque and don’t provide users with definitive proof about the integrity of the process.

After reviewing various solutions, we selected Chainlin...
