A few days ago, I was sitting at a familiar coffee shop near my old workplace, taking the opportunity to work while browsing Binance to ease the headache caused by the market lately.
I happened to read a rather interesting comment: “@Linea.eth that's exactly what MetaMask Chain is.” At that moment, I burst out laughing, thinking it was probably just a fun name, similar to the old memes that called Base “Coinbase Chain.”
@Linea.eth #Linea
But when I looked down, a series of people agreed, analyzed, and even debated very seriously, I began to feel that something was different.
And when thinking deeper for a moment, I realize: indeed, this nickname is not spontaneously given by the community. It arises from the very real feelings of users when stepping into Linea.
I see the vibe of 'MetaMask Chain' appearing before everyone notices it. Simply because the experience of Linea... is familiar to the point of being natural.
When you open MetaMask, $LINEA is there as if it has belonged to the wallet since day one. No need to copy RPC, no need to add networks manually, no unfamiliar feeling. Everything feels like the home you’ve lived in for years but today suddenly has a new, brighter, and more convenient door.
That feeling makes users think that MetaMask and Linea are a twin pair, or at least share the same DNA.
That night I messaged a friend who is building a dApp on Linea, asking how the builders feel. He laughed and said: 'Linea feels like a layer just under MetaMask.'
Building on it is as easy as adding a page to an existing app.' And when I heard that, I understood more: MetaMask is not just a wallet, but a habit. And habits have a power that is hard to describe.
Now, among dozens of Layer-2, users choose Linea simply because… it is the closest to their habits. Using MetaMask for 5 years makes using Linea feel as easy as breathing.
From a technical perspective, I think many people call Linea the MetaMask Chain because it solves a problem that is very close to users' pain points: reducing fees without breaking the Ethereum experience.
Not about 'building something new', not about 'changing the way of use', but about expanding exactly what users are already familiar with. Other rollups may be stronger, faster, but not all provide the feeling of 'I am using Ethereum' like Linea.
This is similar to how MetaMask has long been the bridge between users and Ethereum. Now Linea simply expands that bridge into a boulevard.
Once I tried the MetaMask Portfolio experience on Linea, and I realized one thing: every flow naturally pushes me towards Linea.
Swap? Linea is currently first. Bridge? The same. When MetaMask Portfolio is in action, Linea is almost the default network. It feels just like iPhone suggesting to use iMessage instead of SMS.
Users are starting to think that MetaMask and Linea are a cohesive ecosystem — even though technically they are not 'of each other', but the experience is too seamless.
I've also noticed how Linea builds its community. Not too noisy, not shocking, not spamming tasks.
Every campaign follows the style: 'this is a journey, just take it step by step, and you will understand why this chain is worth using.' Linea Voyage, Linea Park, the small campaigns in MetaMask Portfolio… all designed for onboarding in the true spirit of a builder: gently, not forcefully, for users to discover on their own.
And that is exactly MetaMask's style from day one: not noisy, but infiltrating the habits of millions.
Philosophically, I think Linea reflects what Ethereum has long wanted to pursue: making blockchain the 'invisible' part of the experience. For me, the best blockchain is one where users don't feel like they are using blockchain.
And Linea is very close to this: fast transactions, low fees, no RPC error overload, no worrying about spam pending, no need to manually adjust anything. You just use it — and everything else runs by itself.
One more thing I feel very clearly: Linea does not chase the race of 'beating Solana', 'competing with Arbitrum', or 'competing for TVL with Base'. It does not enter those battles because its philosophy is completely different.
Linea strives to be the smoothest pathway for users to enter Web3, not a battlefield for benchmarking TPS. And at the value level, that is MetaMask's philosophy: to bring users into Web3 safely, simply, and sustainably.
Looking deeper, I think users call Linea the MetaMask Chain because they feel they can trust it. In a market full of new chains, new wallets, and new solutions, MetaMask is still the psychological anchor.
Want to enter Web3? Open MetaMask. Want to try a new chain? Open MetaMask. Want to swap quickly? MetaMask Portfolio. In that context, Linea feels like a 'relative' stepping out from the same family.
Trust MetaMask → trust Linea.
Not many chains have this kind of natural trust.
One day I saw someone on Square comment: 'Linea is the chain that users step into without realizing they are stepping into a new chain.'
And I think this sentence describes it perfectly. Linea doesn't force you to learn anything new, doesn't require you to remember additional network addresses, doesn't change the way you use the wallet. It blends into your habits — just as MetaMask has done over the years.
In conclusion, I see the name 'MetaMask Chain' not as a fun nickname, but as a truth from experience: Linea is where MetaMask becomes more complete, and MetaMask is where Linea reaches millions of users without needing a complex strategy. A wallet is the doorway. A chain is the path.
And for many, the entire Web3 increasingly resembles a long corridor starting from MetaMask and leading to Linea.
I think this relationship is not created by marketing, but shaped by experience. And if Linea continues on this path, it could very well become the default Layer-2 for regular users in the most natural way.
I hope this article helps you understand better why the name MetaMask Chain appears, and why it makes so much sense in the context of Web3 getting closer to the mainstream. If you want more articles about Linea, just let me know.
