Ethereum’s Shifting Landscape: L1 Revival and L2 Redefinition
Ethereum’s ecosystem is undergoing a significant transformation. High-value DeFi protocols are consolidating on its Layer 1 (L1) blockchain, while several independent chains are either returning to Ethereum or re-establishing themselves as Layer 2 (L2) solutions. This trend highlights Ethereum’s continued dominance in decentralized finance and the growing appeal of its scaling solutions.
DeFi’s Return to Ethereum L1
Leading DeFi projects, including Synthetix and Aave, are actively utilizing the Ethereum L1. This indicates a renewed confidence in its capabilities for securing and settling high-value transactions. With a Total Value Locked (TVL) significantly greater than its closest competitors, Ethereum’s L1 remains a central hub for substantial financial activity in the crypto space.
Alt-L1s Embrace the L2 Model
Several prominent blockchain networks are integrating with Ethereum as L2s. This strategic shift offers potential benefits such as reduced operational costs and access to Ethereum’s robust network effects.
Celo’s Cost-Saving Transition
Celo, a mobile-first blockchain, recently transitioned to an Ethereum L2. This move is projected to save the network an estimated $7 million annually in operating expenses by discontinuing its validator network. The decision reflects a broader trend of networks seeking more cost-efficient infrastructure within the Ethereum ecosystem.
Ronin’s Planned Reintegration
Ronin, the blockchain initially developed for the popular game Axie Infinity, announced its intention to return to Ethereum as an L2 in early 2026. This move comes after network congestion previously led Axie Infinity to migrate off the Ethereum mainnet. Jeffrey “Jiho” Zirlin, co-founder of Sky Mavis, the creator of Axie Infinity and Ronin, noted that Ethereum’s scaling roadmap has largely been implemented, making the reintegration feasible.
