What is Linea? Explained & Works

When I first ventured into the world of blockchain, the excitement was palpable, but so was the jargon. Terms like “Layer 2,” “zkEVM,” and “rollup” seemed like a secret code, accessible only to the initiated. If you’ve felt that same initial confusion, you’re not alone. Welcome to a comprehensive guide that will demystify the Linea Ecosystem, a crucial and innovative player in the quest to scale Ethereum and bring decentralized applications to a broader audience.

Linea is not just another blockchain; it’s an Ethereum Layer 2 (L2) scaling solution developed by ConsenSys, a leading blockchain software company known for products like MetaMask. Think of Linea as a superhighway built on top of the foundational Ethereum blockchain. While Ethereum (the “Layer 1” or L1) provides the ultimate security and decentralization, it can sometimes get congested and expensive, especially during periods of high demand. Linea steps in to solve this by offering faster transactions and significantly lower fees, all while inheriting the robust security of Ethereum.

At its core, Linea is a zkEVM rollup. Don’t worry if those terms sound intimidating; we’ll break them down into simple, relatable concepts. Essentially, Linea bundles thousands of transactions off the main Ethereum chain, processes them efficiently, and then submits a tiny, cryptographic “proof” back to Ethereum, verifying that all those transactions were valid. This innovative approach allows for massive scalability without compromising the trust and security that Ethereum is renowned for.

This deep dive will explain the fundamental concepts of cryptocurrency and blockchain, detail how Linea’s ecosystem works, highlight its real-world benefits, address common crypto myths, and guide you on how to get started interacting with Linea. Our goal is to provide a clear, no-nonsense introduction, empowering you to understand and potentially participate in Linea’s vision for a more accessible and efficient decentralized future.

Join me as we explore how Linea is helping to pave the way for the next generation of decentralized applications (dApps) on Ethereum.

Your Foundational Knowledge: Understanding Core Blockchain Concepts

Before we delve into the specifics of the Linea Ecosystem, let’s establish a clear understanding of the fundamental building blocks of this revolutionary technology. If you’re new to crypto, these are the essential terms to grasp.

1. Cryptocurrency: Digital Money for a Digital Age

At its simplest, cryptocurrency is digital money that exists entirely online. Unlike the rupees in your bank account, which are controlled by a central bank or government (a “centralized” authority), cryptocurrencies operate on a decentralized network. This means no single entity has control; instead, a global network of computers collectively verifies and records every transaction. This decentralized nature makes them transparent, secure, and resistant to censorship.

While Linea itself does not have a native “Linea token” for general usage at the time of writing (though a token for governance and decentralization is planned for the future), it uses Ether ($ETH), the native cryptocurrency of Ethereum, for gas fees. This means that if you’re using Linea, you’ll be interacting with $ETH, just as you would on Ethereum’s mainnet. This deep integration makes it very familiar for Ethereum users.

2. Distributed Ledger Technology (DLT) & Blockchain: The Digital Record Book

Imagine a public, continuously growing digital record book where every transaction is meticulously recorded. Now, instead of this record book being stored in one central location (like a bank’s server), copies are maintained and synchronized across thousands of computers around the world. This is the essence of Distributed Ledger Technology (DLT).

A blockchain is a specific, very popular type of DLT. Here’s how it works:

Records (transactions) are grouped into “blocks.”
Each new “block” is cryptographically linked to the previous one, forming a “chain.” Think of it like pages in a digital ledger, where each new page refers back to the one before it with a unique, unalterable “fingerprint.”
Once a block is added to the chain, it’s incredibly difficult to alter or remove, making the record transparent and tamper-proof.

Linea operates as its own independent blockchain, but crucially, it “rolls up” its transactions and cryptographic proofs back to the Ethereum mainnet, inheriting Ethereum’s robust security.

3. Decentralization: Power to the People (and the Network)

This is a core philosophy and a defining characteristic of blockchain technology. Decentralization means that power and control are distributed among many participants in a network, rather than being held by a single, central authority (like a bank, a corporation, or a government).

Why does this matter? This distribution makes the network highly resilient:

To attacks: If one computer or server goes down, the rest of the network continues to function.
To censorship: No single entity can stop or block transactions.
To manipulation: No one party can unilaterally change the rules or records.

Linea is on a roadmap towards progressive decentralization, aiming to distribute control of its core components (sequencers and provers) to the community.

4. Consensus Mechanism: How Everyone Agrees

With thousands of computers independently maintaining the same record book, how do they all agree on which transactions are valid and which new blocks to add to the chain? They use a consensus mechanism. It’s like a set of agreed-upon rules and processes that all participants follow to maintain the integrity and accuracy of the ledger.

Linea, as an Ethereum Layer 2, doesn’t have its own separate consensus mechanism in the same way as a standalone blockchain. Instead, it inherits the security of Ethereum’s Proof of Stake (PoS) consensus. Linea processes transactions off-chain, then bundles them into a “rollup” and submits a cryptographic proof to Ethereum. Ethereum’s PoS validators then verify this proof, essentially securing Linea’s transactions on the mainnet. This “security inheritance” is a key benefit of L2 rollups.

5. Wallets and Keys: Your Digital Vault

A cryptocurrency wallet isn’t a physical container for your crypto, like a leather wallet for cash. Instead, it’s software or hardware that securely stores your private keys. These private keys are unique, secret alphanumeric codes (think of them as super-complex passwords) that prove you own your cryptocurrency on the blockchain and enable you to authorize transactions.

Most wallets, including those compatible with Ethereum and Linea (like MetaMask, Coinbase Wallet, Trust Wallet, etc.), are non-custodial. This is a crucial term: it means you (and only you) retain full control over your private keys and, therefore, your funds. If you lose your private keys or your seed phrase (a list of 12 or 24 words that can regenerate your private keys), you lose access to your crypto forever. This is the ultimate form of financial sovereignty, but it also means ultimate responsibility.

6. Smart Contracts: Self-Executing Agreements

Imagine a traditional contract, but digital, self-executing, and stored directly on a blockchain. Smart contracts are programs that automatically execute when pre-defined conditions are met, without the need for intermediaries like lawyers or banks. For example, a smart contract could automatically release funds to a seller once a buyer confirms receipt of goods.

Smart contracts power a vast array of decentralized applications (dApps) across various sectors, including:

DeFi (Decentralized Finance): Lending, borrowing, and trading financial assets without traditional banks.
NFTs (Non-Fungible Tokens): Unique digital assets representing ownership of art, collectibles, or other items.
Gaming: Creating decentralized game economies.

Linea is a zkEVM (Zero-Knowledge Ethereum Virtual Machine), meaning it is highly compatible with Ethereum’s smart contracts. Developers can deploy their existing Ethereum dApps onto Linea with minimal or no changes, immediately benefiting from lower fees and faster transaction speeds.

7. Decentralized Finance (DeFi): Banking Without Banks

DeFi is a revolutionary movement that aims to recreate traditional financial services (like lending, borrowing, trading, and insurance) using blockchain technology, without relying on centralized intermediaries like banks or brokers.

Key characteristics of DeFi:

Permissionless: Anyone with an internet connection can access DeFi applications.
Transparent: Transactions are recorded on public blockchains.
Immutable: Once recorded, transactions cannot be changed.
Composability: Different DeFi protocols can be combined like “money Lego bricks” to create new financial products.

Linea’s low transaction fees and high throughput make it an ideal environment for DeFi applications, allowing users to engage in activities like swapping tokens, lending, and borrowing without the prohibitive costs often found on Ethereum’s mainnet.

The Linea Ecosystem: Scaling Ethereum with zkEVM Technology

Linea’s core innovation lies in its approach to scaling Ethereum. It leverages cutting-edge cryptographic technology to deliver a high-performance network that is both efficient and secure.

Consider adding an infographic here: “How Linea Scales Ethereum.” Visually depict Ethereum (L1) at the bottom, with Linea (L2) as a layer above it. Show transactions being processed on Linea, then a small “Proof” being sent back to Ethereum. Include icons for “Faster Transactions,” “Lower Fees,” and “zkEVM Compatibility.”

1. The Challenge of Ethereum Scaling: Why Linea is Needed

Ethereum, the pioneer of smart contracts, faces a fundamental challenge: scalability.

High Gas Fees: When the network is busy, the cost of transactions (known as “gas fees,” paid in ETH) can skyrocket, making it expensive for everyday users and small transactions.
Slow Transaction Throughput: The Ethereum mainnet can only process a limited number of transactions per second, leading to congestion and delays.

These limitations hinder widespread adoption of dApps, especially for use cases like gaming, social media, and micro-transactions, where frequent, low-cost interactions are essential.

2. Layer 2 Scaling Solutions: Building on Top

Layer 2 (L2) scaling solutions are protocols built on top of a Layer 1 blockchain (like Ethereum) to increase its transaction processing capacity and reduce costs, while still inheriting the L1’s security. They effectively “offload” a significant portion of the computational work from the main chain.

There are different types of L2 solutions, but Linea utilizes a specific and powerful one: zk-rollups.

3. zk-Rollups: The Magic of Zero-Knowledge Proofs

Rollups work by “rolling up” (batching) hundreds or even thousands of off-chain transactions into a single transaction. This single, compressed transaction is then submitted to the Ethereum mainnet. This significantly reduces the data that needs to be stored on Ethereum, thus lowering costs.

Zero-Knowledge (ZK) Proofs are where the magic happens. A ZK-proof is a cryptographic technique that allows one party (the “prover” – in this case, Linea’s system) to prove to another party (the “verifier” – Ethereum’s mainnet) that a statement is true, without revealing any other information about the statement itself.

In Linea’s context:

Linea processes a batch of transactions off-chain.
It then generates a tiny zero-knowledge proof that mathematically verifies that all those transactions were executed correctly and resulted in a valid new state.
This proof is sent to the Ethereum mainnet.
Ethereum’s smart contracts can quickly and efficiently verify this proof, confirming the validity of all the transactions in the batch, without needing to re-execute them.

This means Linea can offer incredibly high transaction throughput with very low fees, all while benefiting from Ethereum’s robust security model.

4. zkEVM: Ethereum Compatibility Perfected

A zkEVM (Zero-Knowledge Ethereum Virtual Machine) is a type of ZK-rollup that is designed to be EVM-equivalent.

The Ethereum Virtual Machine (EVM) is the runtime environment for smart contracts on Ethereum. It’s essentially the global computer that processes all transactions and smart contract executions.
Being EVM-equivalent means that Linea behaves almost identically to the Ethereum mainnet at the bytecode level. This is a crucial advantage because it allows developers to:
- Deploy their existing Ethereum dApps, smart contracts, and tools onto Linea with minimal or no code changes.
- Benefit from Ethereum’s well-established developer ecosystem, extensive tooling, and battle-tested infrastructure.
- Enjoy a seamless transition between Ethereum and Linea.

This level of compatibility simplifies the development process, accelerates innovation, and makes Linea highly attractive for projects looking to scale.

5. Key Components of the Linea Architecture:

Linea’s architecture involves several sophisticated components working together:

Sequencer: This component collects transactions from users, orders them, executes them on Linea, and then batches them together. Currently, Linea’s sequencer is centralized but with a clear roadmap towards decentralization.
Prover: After transactions are sequenced and executed, the prover generates the cryptographic zero-knowledge proof that confirms the validity of the batch of transactions. This proof is then submitted to Ethereum.
Bridge: A critical component that allows users to securely move assets (like ETH or other tokens) between the Ethereum mainnet and the Linea network. The official Linea Bridge uses the ZK-proofs to ensure asset integrity during transfers.
EVM State Manager: This component keeps track of the global state of the Linea network (e.g., account balances, contract states) and updates it based on executed transactions, preparing the data needed for proof generation.

6. The Role of ETH in Linea

As mentioned, Linea uses Ether ($ETH) for gas fees. This means that if you want to perform transactions on Linea (e.g., swap tokens, mint an NFT, interact with a DeFi protocol), you’ll need ETH in your Linea-compatible wallet.

The ETH you use for gas on Linea is often referred to as “L2 ETH” or “bridged ETH” because you’ve moved it from the Ethereum mainnet to the Linea network via the bridge. A portion of these gas fees on Linea are eventually “rolled up” and paid back to the Ethereum mainnet to cover the cost of submitting the ZK-proofs to Layer 1, thus contributing to Ethereum’s security.

7. Progressive Decentralization

While Linea is currently operated by ConsenSys, it has a clear and public roadmap towards progressive decentralization. This means gradually handing over control of the network’s key operations (like sequencing and proving) to a broader, decentralized community. This commitment to decentralization ensures that Linea will ultimately be community-governed and censorship-resistant, aligning with the core principles of blockchain technology. This includes plans for a potential native Linea token, which would be used for governance and further decentralizing the network.

The “Why”: Real-World Applications and Benefits of the Linea Ecosystem

Linea isn’t just a technical marvel; it’s a practical solution designed to unlock a new era of decentralized applications. Its unique capabilities offer significant real-world applications and benefits for both developers and everyday users.

For Developers & Innovators:

Massive Scalability: Linea’s zk-rollup technology allows it to process thousands of transactions per second (TPS), significantly more than Ethereum’s mainnet. This high throughput is crucial for dApps that require frequent, low-cost interactions, such as gaming, social media platforms, and high-frequency DeFi trading.
Lower Transaction Costs: By batching transactions and using ZK-proofs, Linea drastically reduces gas fees compared to Ethereum mainnet. This makes it economically viable to build and operate dApps that would be too expensive on L1, attracting a wider range of users.
EVM-Equivalence & Developer Familiarity: As a zkEVM, Linea offers near-perfect compatibility with the Ethereum Virtual Machine. This means developers can seamlessly migrate existing dApps, smart contracts, and tooling (like Hardhat, Truffle, Ethers.js, Web3.js) from Ethereum to Linea with minimal code changes. This reduces development time and costs, leveraging Ethereum’s vast developer ecosystem.
Inherited Ethereum Security: Linea inherits the robust security of the Ethereum mainnet. All transactions processed on Linea are ultimately verified by Ethereum’s validators through ZK-proofs. This provides a high level of trust and security without the need for Linea to build its own independent security model from scratch.
ConsenSys Backing & Ecosystem: Developed by ConsenSys, Linea benefits from the extensive resources, expertise, and existing ecosystem of a major Web3 company. This includes integration with MetaMask (the world’s most popular non-custodial wallet), Infura (a leading blockchain API service), and a broad network of developers and partners. This backing provides stability, reliability, and strong support for projects building on Linea.
Growing Ecosystem of dApps: Linea is rapidly attracting a diverse range of dApps across DeFi, NFTs, gaming, and social platforms, creating a rich environment for developers to build upon and integrate with.

For Everyday Users:

Significantly Lower Gas Fees: This is perhaps the most immediate and tangible benefit for users. Interacting with dApps on Linea, whether it’s swapping tokens on a DEX, minting an NFT, or playing a blockchain game, will cost a fraction of what it would on Ethereum mainnet. This democratizes access to decentralized applications.
Faster Transactions: Experience near-instant transaction confirmations. No more waiting minutes (or even longer during peak times) for your transaction to go through. This makes the user experience much smoother and more akin to traditional web applications.
Access to Innovative dApps: Linea’s ability to host scalable and cost-effective dApps means you’ll find new and exciting projects emerging on the network. This includes:
- DeFi: Engage in lending, borrowing, and swapping with reduced costs, potentially leading to more efficient capital utilization.
- Gaming: Play blockchain-based games with seamless, low-cost in-game transactions, making the gameplay experience more fluid and enjoyable.
- NFTs: Mint, buy, and sell NFTs without breaking the bank on gas fees, opening up the world of digital collectibles to a wider audience.
- SocialFi: Participate in decentralized social applications where micro-interactions are affordable and fast.
Seamless User Experience (UX): Because Linea is EVM-equivalent, most familiar Ethereum wallets (like MetaMask) and tools work effortlessly. This means a low learning curve for existing Ethereum users.
Security of Ethereum: You can transact on Linea with confidence, knowing that the underlying security is rooted in the battle-tested Ethereum mainnet. Your assets are ultimately secured by Ethereum’s robust consensus mechanism.
Future Potential: Being an early adopter or user on Linea positions you to potentially benefit from its future growth and decentralization roadmap, including potential token launches or community incentives.

Dispelling the Myths: Addressing Common Crypto Misconceptions (and Linea’s Context)

As someone who has navigated the crypto space for a while, I’ve heard countless misconceptions that often cloud people’s understanding. It’s crucial to address these myths directly, especially when discussing a project like Linea, which emphasizes legitimate utility, robust security, and real-world innovation.

“Cryptocurrency is only for criminals and illicit activities.”
- Reality: This persistent myth is largely a misconception. While any form of value, including traditional cash, can be used for illicit purposes, public blockchains (like Ethereum and its Layer 2s like Linea) are inherently transparent. Every transaction – whether it’s an ETH transfer, a DeFi swap, or an NFT mint – is permanently recorded on an immutable, public ledger. This makes it traceable by law enforcement and blockchain analytics firms. In fact, this transparency often makes crypto less suitable for large-scale criminal operations than traditional financial systems that can operate in shadows. The vast majority of crypto transactions are for legitimate uses like remittances, payments, and, in Linea’s case, enabling a highly scalable and efficient decentralized application ecosystem.
- Context for Linea: Linea is designed as a transparent, public blockchain focused on providing a platform for legitimate innovation and decentralized applications. Its core mechanisms, including the public verifiability of its ZK-proofs on Ethereum, are built for open and auditable interactions. The platform’s emphasis on accessibility and empowering developers and users for ethical participation directly counters the idea of it being a platform for illicit endeavors.
- Trustworthiness Principle: “When engaging with any digital currency or distributed ledger platform, it’s crucial to understand that transactions on a public ledger are permanently recorded and transparent. While unfortunately, some illicit activities have been associated with cryptocurrencies, the very design of public DLTs, which Linea exemplifies, enhances accountability rather than enabling illicit activity. Linea’s comprehensive ecosystem, focused on enabling cutting-edge development and user empowerment for various dApp categories, directly counters the notion of it being a platform solely for illicit endeavors. We encourage users to always verify information through official channels and understand the inherent transparency of public blockchains.”
“All crypto is a scam/Ponzi scheme.”
- Reality: The crypto space has, regrettably, seen its share of fraudulent projects, “rug pulls” (where developers abandon a project and run off with investor funds), and “pump-and-dump” schemes. However, it’s a grave error to brand all cryptocurrencies this way. Legitimate projects offer genuine technological innovation, solve real problems, have transparent development processes, and are built by dedicated teams with long-term visions. Their value is derived from their utility, adoption, and the problems they solve, not solely from attracting new investors in a pyramid scheme.
- Context for Linea: Linea is developed by ConsenSys, a highly reputable and well-established company in the blockchain space. ConsenSys is a major contributor to the Ethereum ecosystem and is responsible for widely used products like MetaMask and Infura. Linea has publicly available documentation, an open-source code base, and a clear roadmap for progressive decentralization. Its utility is tangible: it provides a vital scaling solution for Ethereum, enabling faster and cheaper transactions for a wide range of dApps. Its value proposition is tied directly to its technical innovation (zkEVM) and its ability to solve real-world problems of high gas fees and slow throughput on Ethereum.
- Authoritativeness Tip: “To assess the legitimacy of any DLT project, including Linea, it’s essential to look beyond market speculation and examine its fundamental purpose and technological underpinnings. Does it solve a real problem (e.g., scaling the Ethereum blockchain to make dApps more accessible and affordable)? Is its underlying technology (zk-rollups, EVM-equivalence) robust, innovative, and its code open-source and auditable? Does it have a clear and publicly available roadmap, a history of consistent development, and a dedicated, active team and community? Are there real products and demonstrable adoption, particularly with its dApp ecosystem? Linea’s strong technical foundation, its backing by a reputable entity like ConsenSys, and its commitment to progressive decentralization are strong indicators of its commitment to long-term utility and legitimate growth. We believe in transparent education, encouraging our readers to always conduct their own deep due diligence, consult official project documentation, and evaluate the technology’s actual utility and track record very carefully.”
“Crypto is bad for the environment because of mining.”
- Reality: This myth primarily applies to older Proof-of-Work (PoW) based cryptocurrencies like Bitcoin, which do consume significant energy due to their “mining” process (solving complex computational puzzles). However, many newer DLTs and evolving ones utilize far more energy-efficient consensus mechanisms.
- Context for Linea: Linea is an Ethereum Layer 2 solution. Ethereum itself transitioned from Proof-of-Work to Proof of Stake (PoS) with “The Merge” in 2022, which drastically reduced its energy consumption (by over 99%). Since Linea inherits its security from Ethereum’s PoS, and its own operations do not involve energy-intensive mining, Linea is a highly energy-efficient blockchain solution. The cryptographic proofs it generates are computationally intensive, but they are a small fraction of the energy required by PoW mining. Therefore, concerns about high energy consumption are largely inapplicable to the Linea network.
“It will replace all money / it’s not real money.”
- Reality: While cryptocurrencies offer a new form of digital value, the idea that they will completely replace all traditional fiat currencies in the near future is highly unlikely. Most cryptocurrencies are not designed to be a universal replacement for national currencies but rather to serve specific purposes (like powering a decentralized application, enabling faster international transfers, or acting as a store of value). Governments are also actively exploring central bank digital currencies (CBDCs) and regulations that would allow coexistence rather than full replacement. However, cryptocurrencies are increasingly recognized as valuable digital assets and are accepted as payment in various contexts, proving their “real” value and utility.
- Context for Linea: Linea’s primary purpose is to scale Ethereum, making it more efficient and accessible for decentralized applications. It uses $ETH as its gas token, which is a widely recognized digital asset. Linea is not designed to replace traditional money, but rather to enhance the utility and reach of decentralized digital economies. The “realness” of the ETH used on Linea comes from its tangible utility: its ability to pay for transactions, interact with smart contracts, and enable a new generation of low-cost, high-throughput dApps. It’s a critical infrastructure for the future of Web3, creating new ways for value to be exchanged and for applications to function, complementing traditional financial systems.

Getting Started: A Beginner’s Perspective on Acquiring & Using ETH on Linea

If the vision of a scalable, efficient, and user-friendly Ethereum ecosystem like Linea excites you, you might be curious about how to acquire and interact with it. This section provides a beginner-friendly overview. This information is purely for educational purposes and should not be considered financial, investment, or legal advice. Always prioritize security and conduct your own extremely thorough research before proceeding.

Understanding What You’ll Need:
- Ether ($ETH): The native cryptocurrency of Ethereum, used for gas fees on Linea.
- Compatible Wallet: A non-custodial wallet that supports Ethereum and Layer 2 networks like Linea (e.g., MetaMask, Coinbase Wallet, Trust Wallet).
Acquiring ETH (on Ethereum Mainnet first):
- 1. On Centralized Exchanges (CEX): This is typically the easiest and most common way for beginners to acquire ETH, especially if you’re starting with traditional money (fiat).
  - Step 1: Identify Exchanges: Major cryptocurrency exchanges like Binance, Kraken, Coinbase, WazirX (in India), etc., allow you to buy ETH directly with fiat currency.
  - Step 2: Sign Up and Complete KYC (Know Your Customer): This is a mandatory step for regulated centralized exchanges. You’ll need to provide identification documents (e.g., Aadhar Card, PAN Card in India) and sometimes proof of address.
  - Step 3: Deposit Fiat Currency (e.g., INR) or another Cryptocurrency: Once your account is verified, fund your exchange account. You can typically do this via bank transfer, UPI (if supported by your chosen exchange in India), or by depositing other cryptocurrencies you already own (like USDT).
  - Step 4: Buy ETH: Navigate to the trading section of the exchange. Find the ETH trading pair (e.g., ETH/INR, ETH/USDT). Enter the amount of ETH you wish to buy and execute your order.
  - Step 5: Withdraw ETH to Your Personal Non-Custodial Wallet (Highly Recommended): While you can leave your ETH on the centralized exchange, for true ownership and to interact with Linea, it’s strongly recommended to withdraw your ETH to your personal non-custodial wallet (like MetaMask). Always double-check the recipient address and ensure it’s the correct Ethereum mainnet address generated by your wallet! Sending crypto to the wrong address can result in permanent loss.
Bridging ETH to Linea: Moving Your Funds to the Superhighway

Once you have ETH on the Ethereum mainnet in your non-custodial wallet, you’ll need to “bridge” it to the Linea network to use it for transactions on Linea.

Step 1: Add Linea Network to Your Wallet:
- For MetaMask users: Go to Chainlist.org, search for “Linea,” and click “Add to MetaMask.” Approve the prompts. This will configure your wallet to interact with the Linea network.
- Alternatively, you can manually add the network details (available on the official Linea documentation).
Step 2: Use the Official Linea Bridge: The most recommended way to move assets to Linea is via the official Linea Bridge.
- Go to the official Linea Bridge website (usually bridge.linea.build or a link from the official Linea website, linea.build).
- Connect your MetaMask (or other compatible) wallet. Ensure your wallet is currently connected to the Ethereum Mainnet.
- Select the amount of ETH you want to bridge from Ethereum to Linea.
- Confirm the transaction in your wallet. Be aware of the Ethereum mainnet gas fees for this bridging transaction, as it’s an L1 transaction.
- Important: Bridging takes some time. While the transaction on Ethereum might confirm quickly, it can take anywhere from a few minutes to longer for the funds to appear on the Linea network due to the rollup process.
Step 3: Alternative Bridges (Use with Caution): While the official bridge is recommended, various third-party bridges (like Orbiter Finance, Synapse Protocol, etc.) also support bridging to Linea. These can sometimes offer faster or cheaper options for certain assets, but always do your research on their security and reputation before using them.
