To identify potential airdrop opportunities on emerging blockchains:

Track Early Activity: Monitor chains with sudden TVL spikes (DefiLlama) or developer commits (GitHub).

Engagement Rewards: Join testnets, complete quests (Galxe, Layer3), and interact with new dApps—active wallets often qualify.

VC-Backed Projects: Research teams funded by top crypto VCs (a16z, Paradigm), as they frequently use airdrops for distribution.

Community Hubs: Follow Discord/TG groups where devs hint at future token plans (e.g., "governance token" discussions).

Chain-Specific Trends:

Modular chains (Celestia ecosystem) often reward early rollup users.

EVM-compatible L2s (Base, Scroll) target power users for retroactive drops.

Prioritize projects with clear utility—avoid "farm-and-dump" schemes.
