NFT trading card game 9tales NFT has integrated Chainlink VRF on Polygon
9Tales (TCG) has integrated Chainlink Verifiable Random Function (VRF) on Polygon mainnet to help power a fair rewards system in our new experience called DAWN. 9tales DAWN is a tokenized experience that will accompany the launch of the alpha version and aims at rewarding the 9Tales community for their feedback on this pre-release of the 9Tales TCG game. Players are rewarded with tokens for mastering the game and/or providing constructive feedback. They can then redeem these tokens and receive randomly selected gifts from a gift pool.
