Description:

My favorite TikTok influencer told me that NFTs are about to blow up again. Since NFTs can otherwise be copied, this project implements access control where only people who previously owned the token can access the jpgs. This ensures only the ones who wear the freshest clothes, eat at the chillest restaurants and hang out with the hottest dudes get access to these rare pepes :^)
