To screen high-potential airdrop projects using whitepapers and community activity, start by analyzing the whitepaper for a clear vision, detailed roadmap, and robust tokenomics—ensure the team has credible experience. Next, assess community engagement on platforms like Twitter, Discord, or Telegram; look for consistent interaction, organic growth (e.g., 10K+ active members), and developer activity on GitHub (frequent commits signal progress). Cross-check claims with X posts for sentiment, but prioritize projects with tangible updates over hype. Focus on those with scalable use cases and avoid vague or overly promising documents.
