[Frontend/Contract] Build Token Airdrop Manager with Merkle Tree Distribution and Anti-Sybil Protection

[ayomideadeniran]

📋 Overview

Labels: smart-contract complexity: hard eta-2-days airdrop merkle-tree distribution

🎯 Problem Statement

Token airdrops are expensive and vulnerable to sybil attacks. The platform needs a merkle tree-based airdrop system with anti-sybil protection for efficient and fair distribution.

📝 Task Breakdown

Phase 1: Merkle Tree Setup (0.5 days)

• Implement merkle tree generation from recipient list
• Create merkle root storage on-chain
• Add proof verification logic
• Build recipient eligibility checking

Phase 2: Claim Mechanism (0.5 days)

• Implement token claim with merkle proof
• Create one-time claim enforcement
• Add claim status tracking
• Build claim deadline

Phase 3: Anti-Sybil Protection (0.5 days)

• Implement identity verification requirement
• Create sybil detection heuristics
• Add claim limits per identity
• Build blacklist for detected sybils

Phase 4: Frontend Interface (0.5 days)

• Create airdrop claim interface
• Build eligibility checker
• Add claim status display
• Implement airdrop analytics

✅ Acceptance Criteria

• Merkle proofs verified correctly
• Claims processed accurately
• Sybil attacks prevented
• One-time claim enforced
• Frontend guides users through claiming
• All operations emit proper events

📁 Files to Create

• contracts/src/airdrop_manager.rs
• contracts/src/merkle_distributor.rs
• frontend/src/components/airdrop/AirdropDashboard.tsx

🎯 Success Metrics

• Claim processing <2 seconds
• Sybil detection >90% accurate
• Gas-efficient distribution
• Support for 100000+ recipients
