Airdrops concentrate on chains with high user interaction, diverse dApp ecosystems, and low claim friction. Historically, Ethereum and its Layer-2 networks (Arbitrum, Optimism, zk-rollups) see many retroactive drops due to heavy DeFi and NFT activity. Solana and Polygon also host frequent campaigns because of fast, low-cost transactions that attract builders and users. Emerging chains with active testnets or grant programs—plus ecosystems promoting developer incentives—frequently run airdrops to bootstrap participation. Smaller chains sometimes run aggressive bounty programs to attract liquidity, but distribution quality varies. Track ecosystems where onboarding, bridging, and dApp engagement are highest to find consistent airdrop activity.
