The Ethereumâs Layer 2 (L2) players have been performing exceptionally well to date, with impressive TVLs in the ecosystems of Arbitrum, Polygon, and Optimism as the market rebounds. Among these, Arbitrum has the largest TVL, accounting for almost 50% of L2 markets and 3% of the entire Ethereum mainnet. Arbitrum has consistently demonstrated strong operational capabilities with technical upgrades: the launch of dual mainnets â Arbitrum Nova and Arbitrum One and the debut of a brand new programming language, Stylus. The release of Odysseyâs weekly event has also generated significant attention to the ecosystem. Meanwhile, in the long run, as suggested by Vitalik, ZK Rollups might likely have more technical breakthroughs than Optimism Rollups and will become the leading L2 solution.
