Ethereum’s Evolving Landscape: A Resurgence of Layer 1 and the L2 Migration Trend
Ethereum’s core blockchain (Layer 1) is experiencing renewed interest from significant decentralized finance (DeFi) projects, even as several alternative Layer 1 (alt-L1) networks transition to become Layer 2 (L2) solutions within the Ethereum ecosystem.
This dynamic shift highlights a continuous evolution in blockchain strategy, driven by economic efficiencies and the pursuit of stronger network effects.
DeFi Giants Reaffirm Ethereum L1
High-value DeFi protocols, including Synthetix and Aave, are reportedly reinforcing their commitment to the Ethereum Layer 1. This trend underscores Ethereum’s established position as a foundational platform for substantial financial applications.
The network’s Total Value Locked (TVL) significantly surpasses its closest competitors, indicating its continued dominance in the DeFi space.
Alt-L1s Embrace the L2 Model
Conversely, several independent blockchains are opting to integrate with Ethereum as Layer 2s. This strategic move can unlock considerable cost savings and leverage Ethereum’s extensive user base and developer community.
Celo’s Cost-Saving Transition
Mobile-first blockchain Celo, for instance, transitioned to an L2 solution earlier this year, discontinuing its independent validator network. This change is projected to generate annual operational cost savings of approximately $7 million.
Ronin’s Planned Return to Ethereum
In a similar vein, the Ronin blockchain, known for hosting the game Axie Infinity, announced its intention to rejoin the Ethereum ecosystem as an L2 by early 2026. This move comes after network congestion previously led Axie Infinity to migrate off the Ethereum mainnet.
Jeffrey Zirlin, co-founder of Sky Mavis, the creator of Axie Infinity and Ronin, noted that Ethereum’s scaling progress played a role in this decision. The L2 model offers a path for these projects to benefit from Ethereum’s security and liquidity while addressing scaling challenges and reducing operational overhead.
