Ethereum’s Shifting Landscape: L1 Revival and L2 Integration
The blockchain ecosystem is witnessing a dynamic period of repositioning as projects re-evaluate their strategies regarding Ethereum’s Layer 1 (L1) and Layer 2 (L2) solutions. High-value Decentralized Finance (DeFi) protocols are reinforcing Ethereum’s core, while several standalone blockchains are opting to integrate as L2s.
The Allure of Ethereum L1 for DeFi
Ethereum’s mainnet continues to be a dominant force in DeFi. With a Total Value Locked (TVL) significantly higher than its closest competitors, it remains a primary hub for substantial financial applications. This demonstrates enduring confidence in its security and established infrastructure for high-value transactions.
Alt-L1s Embrace the L2 Model
Recent trends show several alternative Layer 1 blockchains transitioning to Ethereum’s L2 ecosystem. This move is driven by potential cost efficiencies and the opportunity to leverage Ethereum’s extensive network effects. The L2 model offers substantial savings in operational expenses, a critical factor for long-term sustainability.
Celo’s Strategic Shift
Celo, initially a mobile-first blockchain, made a significant move by transitioning its validator network to become an Ethereum L2. This strategic decision is projected to result in annual operational savings of approximately $7 million, highlighting the financial benefits of L2 integration.
Ronin’s Return to Ethereum
Ronin, the blockchain behind the popular game Axie Infinity, also announced its plans to re-integrate with Ethereum by early 2026. This decision marks a return to the Ethereum ecosystem after prior network congestion issues. Jeffrey Zirlin, co-founder of Sky Mavis, the creator of Ronin and Axie Infinity, noted Ethereum’s progress in addressing scaling challenges, suggesting that the original scaling roadmap has largely been fulfilled.
DeFi Protocols Reconfirming L1 Commitment
While some L1s are becoming L2s, several prominent DeFi projects, such as Synthetix and Aave, are actively continuing their development and operations directly on Ethereum’s mainnet. This reinforces Ethereum L1’s role as the foundational layer for substantial and established DeFi protocols.
