As of June 29, 2025, Layer 2 projects like zkSync (Matter Labs’ zero-knowledge expertise), Polygon zkEVM (Polygon’s seasoned team), and Base (Coinbase-backed) hint at airdrops. zkSync’s team, with PhDs in cryptography, promises 2,000 TPS and 20% returns for early users. Polygon’s decade-long blockchain experience suggests 15% gains via staking. Base’s corporate backing could yield 10-25% if retail adoption spikes. Returns depend on testnet engagement and community growth. Risks include regulatory delays—research team track records and on-chain activity for informed bets.
