HashDrop is a cross-chain, AI-powered hashtag reward engine built for DAOs, brands, and communities. It turns social media hashtag participation (like tweets, casts) into verifiable on-chain achievements — delivering rewards such as NFTs or tokens based on the quality of participation.
HashDrop is a decentralized platform that enables brands and creators to launch hashtag-based social media campaigns with automatic NFT rewards. The system monitors social media engagement (specifically Farcaster) and distributes NFT rewards to participants based on their engagement scores.
