Ethereum is still king when it comes to decentralization and network security, but let’s face it—L2s are where the real action is happening. The explosion of Optimistic Rollups and ZK Rollups is driving scalability, reducing gas fees, and bringing real-world applications closer to mass adoption.

Arbitrum and Optimism continue to dominate TVL, but don’t sleep on the rising stars like Base (Coinbase's L2) and ZKsync. These aren’t just experiments anymore—they’re ecosystems with growing dev communities and real user traction.
