ENS Comes Home to Ethereum L1
ENSv2 just shipped on mainnet instead of its planned rollup. It's the latest in a quiet exodus away from L2s.

ENSv2 is live on Ethereum mainnet — and that address tells the whole story. Instead, the biggest upgrade in the protocol's history shipped on L1, where ENS registration gas costs had already dropped 99% over the prior year. [1]
ENSv2 is not a minor patch. [1] ENS currently supports over 36 million names across .eth and ecosystem namespaces, integrated into 600+ applications that support name resolution, from DeFi apps like 1inch, Jumper and Lighter, to wallets like MetaMask and Safe. [2]
The U-turn on Namechain came down to math. On Feb. 6th, ENS founder Nick Johnson explained the U-turn: "Ethereum L1 is scaling, and it's scaling faster than almost anyone predicted two years ago." [1] An L2 would have added trust assumptions that L1 doesn't carry. When Johnson published that reasoning, Vitalik Buterin signed off the same day: "It's a good decision!" [1]
ENS is not alone in reversing course. Ethereum's gas limit doubled from 30M to 60M over the course of 2025, pulling L1 fees down with it. [1] That shift has made the economics of running a separate chain look far worse by comparison. Synthetix, one of the first protocols to launch on an Ethereum rollup back in 2021, published a post in June 2025 titled "L2s are Dead, Long Live Ethereum," citing fragmented liquidity. Its new perps exchange opened on L1 in December. [1]
The migration wave accelerated sharply through October. Blast announced on Oct. 2nd that it's winding down because its costs exceeded its chain revenue. Abstract said on Oct. 6th that it's shutting down on Dec. 15th, calling a consumer-only chain "unsustainable as a standalone model." [1] ShapeShift moved its rFOX staking program from Arbitrum to L1 on Oct. 1st. Nillion took its Blacklight network live on L1 on Oct. 5th. [1]
What's emerging is less a rejection of the multi-chain thesis than a sorting of what actually needs a chain. The most critical stuff — ownership, custody, settlement — is returning to where trust is deepest. The cheaper, faster work goes wherever costs least.
ENSv2 itself illustrates this split. The NFT names and core contracts live on L1, but cheap and gasless subnames can still resolve from L2s or offchain via CCIP-Read, a standard that lets a name point to data stored elsewhere. [1] Synthetix's new perps match orders offchain but settle on Ethereum L1. [1] State and compute are quietly decoupling.
The longer horizon holds open questions. [1] If applications return to L1 faster than block capacity grows, fees climb again and the math flips. Meanwhile, the Ethereum Economic Zone is an effort to give Ethereum and its rollups synchronous composability, letting contracts on different chains interact within a single transaction — a path that could make the L1/L2 distinction matter less rather than require picking sides. [1]
The direction is clear, even if the destination isn't fixed. Builders who bet on their own chains are reconsidering. Protocols that need trust are moving to where trust is cheapest to verify. The infrastructure is reorganizing itself around a simple question: what actually has to live here?
If you already hold a .eth name, ENSv2 is waiting. When ENS launched in 2017, a name like alice.eth offered a recognizable way to interact with an Ethereum account. [2] Eight years later, the protocol behind it has been rebuilt — and it chose to stay home.
I spent two years of my life memeing the L2 narrative into existence. It didn't work out well for Synthetix in the end hence back to mainnet.Kain Warwick
