Fair cross-chain airdrops typically focus on equal opportunity, transparent eligibility, and proportional distribution. Mechanisms that snapshot activity across multiple chains, reward verified users, and prevent double-claiming ensure fairness. Some projects use on-chain proofs or Merkle tree-based claims to allocate tokens accurately without bias. Weighted distribution based on consistent engagement rather than capital size can also improve fairness. Additionally, combining time-based participation or social verification helps reduce bot exploitation and opportunistic claims. A well-designed cross-chain airdrop ensures that users interacting meaningfully across ecosystems receive proportionate rewards, maintaining equity while encouraging long-term engagement.
