AdManager - Powered by Chainlink VRF

The primary objective of the AdManager Smart Contract is to offer a fair and unbiased method for selecting the next advertisement to display. At SignWise, we advocate equal visibility for all companies, prioritizing randomness over favoring a specific company willing to pay more for their ads to appear first. Leveraging the capabilities of Chainlink's Verifiable Randomness Function (VRF), we achieve this impartial selection process.
