ENS Drops Namechain Plan as More Crypto Projects Move Core Activity Back to Ethereum L1
Ethereum Name Service has rolled out ENS v2 directly on Ethereum mainnet, abandoning the Layer 2 path it had spent years preparing through its planned Namechain rollup. The move is part of a wider pattern described in the source article: a growing list of crypto projects are stepping back from dedicated L2 deployments, shelving custom chain plans, or shutting down live networks and returning core contracts to Ethereum L1. The article ties that shift to Ethereum’s higher block gas ceiling in 2025, which rose from 30 million to 60 million and pushed L1 transaction fees lower, while the cost of operating an app-specific chain has become harder to justify. It cites ENS, Synthetix, Superseed, Trueo, ShapeShift, Blast, Nillion, and Abstract as examples. At the same time, projects are not simply moving every function back on-chain. A common design pattern is emerging: custody, ownership, and settlement stay on Ethereum L1, while matching, computation, or other heavy tasks run off-chain or in cheaper environments. The piece also points to Ethereum Economic Zones and the idea of ephemeral rollups as efforts to redraw the boundary between L1 and L2 rather than erase it.
