2025 may see airdrops from zkSync Hyperchain, Optimism Bedrock, and Arbitrum Nitro. ZkSync’s team (Mute Swap alumni) plans to reward early adopters with 3% of ZKS supply, targeting developers and liquidity providers. Optimism’s "Superchain" initiative could airdrop 2% to ecosystem projects, favoring DeFi protocols with TVL >$100M. Arbitrum’s focus on gaming may allocate 1.5% to NFT marketplaces. Historically, Layer 2 airdrops yield 5-20x returns—expect similar ranges, but prioritize projects with strong technical roadmaps.
