"The Cult of Randomness"

Just as the lottery was a key part of the Athenian democracy, we believe that chance is the fairest way to distribute value. For that reason, we don't only use VRF for minting, we push the cult of randomness further by using chainlink VRF all game mechanics: - Fights - Stats allocation - Skills allocation - Training scrolls - Piñatas - Lottery VRF is the best tool as a tamper-proof random number generator to build reliable smart contracts for any applications which rely on unpredictable outcomes.

Before you can tell your friends you’ve found the next big thing, Chainlink will call back our smart contract with a random number, and that number is assigned to your Luchador NFT :
