Ethereum’s Evolving Landscape: L1 and L2 Dynamics
The blockchain ecosystem is experiencing a notable shift, with various projects re-evaluating their strategies concerning Ethereum’s Layer 1 (L1) and Layer 2 (L2) solutions. High-value Decentralized Finance (DeFi) protocols, such as Synthetix and Aave, continue to thrive on the Ethereum mainnet, underscoring its enduring appeal for significant financial applications. Simultaneously, several Layer 1 blockchains, including Ronin and Celo, are transitioning to become Ethereum L2s, seeking to leverage its established network effects and enhanced scalability.
This trend highlights a complex interplay where some projects embrace L2s for efficiency, while others, even those previously on L2s, consider returning to the Ethereum mainnet. The Ethereum L1 boasts a Total Value Locked (TVL) significantly greater than its closest competitors, reinforcing its position as a primary hub for DeFi innovation.
Cost Savings and Network Effects Drive L2 Adoption
Moving to an L2 can offer substantial financial benefits and strategic advantages. The L2 model promises considerable savings in operational costs and provides access to Ethereum’s vast user base and developer community.
Celo, a mobile-first payments network, exemplified this migration. Earlier this year, Celo deactivated its validator network to integrate as an L2. This move is projected to save the project nearly $7 million annually in operating expenses, demonstrating the economic incentives behind such transitions.
Ronin’s Return to the Ethereum Ecosystem
Blockchain gaming platform Ronin is also preparing for a significant change. In August, the team behind Ronin announced plans to reintegrate with Ethereum by early 2026. This decision follows a period where network congestion on Ethereum previously prompted Ronin’s popular game, Axie Infinity, to operate independently on its own chain.
Jeffrey “Jiho” Zirlin, co-founder of Sky Mavis, the company behind Axie Infinity and Ronin, observed that Ethereum has largely delivered on its scaling objectives. This improved scalability appears to be a key factor in Ronin’s strategic return, aiming to benefit from Ethereum’s revitalized architecture and robust ecosystem.
