Skeptics of Ethereum's rollup-centric roadmap have raised concerns about layer-2 networks potentially separating from the ecosystem, but this hasn't happened. Instead, independent layer-1s like Celo and Lisk are re-architecting themselves as L2s. Celo, originally launched in 2020 as a mobile-first L1, migrated to an Ethereum rollup model in March 2025, citing benefits like security and community from Ethereum. This migration led to significant growth, showcasing over 600,000 daily active users and more than $1 billion in monthly stablecoin volume. Similarly, Lisk transitioned its token to Ethereum in May 2024 and reported an impressive 48 million transactions post-migration. The shift highlights a trend where more layer-1s are opting to integrate into Ethereum's ecosystem rather than pursue independence, reinforcing Ethereum's role as a central hub for scalability and security. The article suggests that this trend promises lower fees and improved user experiences within the Ethereum network.
