Targeted Marketing and Precision Airdrops for the Next Generation of On-Chain Audiences

CrossDrop was recognized as a top-tier solution for the Arbitrum ecosystem, demonstrating the power of targeted distribution in the L2 landscape.

In the current Web3 landscape, Airdrops are the primary tool for user acquisition. However, they face a critical efficiency gap:

• Sybil Vulnerability: Automated bots dilute rewards intended for real users.
• Shotgun Marketing: Distribution is often broad and unoptimized, leading to low retention.
• Lack of Profiling: Companies cannot easily identify power users or loyal community members across chains.

CrossDrop transforms airdrops from a "quantity-play" into a "quality-play." By leveraging deep on-chain analytics, we enable businesses to execute Targeted Marketing with surgical precision.

"We help protocols find their true champions, not just their loudest farmers."

• What is an Airdrop? A strategic tool for Web3 projects to distribute tokens to a community based on specific criteria.
• The CrossDrop Edge: We don't just drop tokens; we drop them to the right people based on transaction history, social graph (Airstack), and NFT ownership (SimpleHash).

• 🎯 On-Chain Targeting: Filter audiences based on specific protocol interactions.
• 🔗 Cross-Chain Insights: Aggregated data from multiple networks to build a complete user persona.
• 🛡️ Sybil Resistance: Intelligent filtering to prioritize organic wallets.
• 📊 Marketing Dashboard: A core development console for PMs to track campaign conversion and impact.

• L1/L2 Infrastructure: Built on Arbitrum for high-speed, low-cost execution.
• Data Intelligence:
  • Airstack GraphQL API: For complex social and transactional graph queries.
  • SimpleHash API: For multi-chain NFT data aggregation.
• Verification & Access: Crossmint modules for seamless NFT integration.
• Frontend: React (Vite) + Chakra UI + Framer Motion.
• Backend: Node.js (Express) + MongoDB (Mongoose).
