ENS v2 launches on Ethereum L1, joins wave of projects migrating from Layer 2s

Ethereum Name Service (ENS) v2 launched directly on Ethereum mainnet on October 27, abandoning its planned Rollup network Namechain. This move reflects a broader trend: over the past year, projects including Synthetix, Trueo, Blast, and Abstract have migrated or announced plans to migrate back to Ethereum L1. The shift is driven by Ethereum's block gas limit increase from 30 million to 60 million in 2025, which significantly lowered L1 transaction fees, and the high cost of maintaining independent chains. ENS v2 retains core ownership and settlement on L1 while moving computationally intensive domain resolution to L2 or off-chain via CCIP-Read, separating state storage from execution.
