🌀Linea Network Guide

🚀 About Linea Network

Linea is a Layer 2 Rollup solution powered by Zero-Knowledge Proofs (ZKPs). Unlike Optimistic Rollups, Linea guarantees transaction finality directly through mathematical proofs. As a core pillar of the Consensys product suite—deeply integrated with MetaMask and Infura—it provides industry-leading security and premier developer tool support.

SlerfTools has fully integrated the Linea ecosystem, offering a complete suite of ready-to-use tools for Token Creation, Airdrops, Trade Execution, and Wallet Management.

⚠️ Note on Network Configuration & Support: This page provides the RPC parameters required to switch your wallet to the Linea network.

• Consistent Workflow: Once the network is switched, the operational workflow for all features remains identical to the BSC (BNB Chain) experience.

• Tutorial Note: To maintain a unified documentation style, tutorial screenshots may still use the BSC interface as an example. However, the UI and steps for Linea are exactly the same—you can follow the visual guides step-by-step without any adjustments.

⚙️ Step 1: Network & RPC Configuration

🌟 Note: The Linea Mainnet is operating stably and is typically pre-integrated into the MetaMask network list (though it may need to be toggled "on" in some versions). If you need to add the network manually, please use the following parameters:

🔌 Linea Mainnet Parameters

• Network Name: Linea Mainnet

• RPC URL: https://rpc.linea.build (Official Infura Node)

• Chain ID: 59144

• Currency Symbol: ETH

• Block Explorer: https://lineascan.build

🛠 Step 2: Core Functional Guide

SlerfTools is fully compatible with Linea’s zkEVM environment, providing you with a secure, high-speed, and seamless on-chain tool experience.

Universal Operating Instructions (Must Read)

To ensure consistent maintenance across our documentation, the tutorials below may use the BSC (BNB Chain) interface for demonstration purposes. When operating on Linea, the logic remains exactly the same.

👉 You simply need to:

• Follow the Workflow: Execute the same clicking sequence and steps as illustrated in the guides.

• Asset Equivalence: Treat any BNB shown in the screenshots as ETH on the Linea network.

• Network Verification: Always double-check that your wallet is connected to Linea Mainnet (Chain ID: 59144) before initiating any transaction.

🪙 One-Click Token Launch

Standard Token Creation (Linea ERC20)

• Leverage the cost-efficiency of zkEVM to rapidly deploy your project tokens. Assets created on Linea are designed for instant recognition across the MetaMask ecosystem.

⛽️ Gas Fees: Overview & Optimization (ETH)

Following the Alpha v2 upgrade, Linea’s gas mechanism has seen significant improvements, primarily through the drastic compression of Call Data costs.

1. Fee Overview

• Standard Transactions: Paid in ETH. Interaction costs on Linea have stabilized within the $0.05 – $0.15 range, representing an 80% reduction since the network's inception.

• zk-Proof Costs: Unlike Optimistic Rollups, Linea’s fees include the computational cost required to generate Zero-Knowledge proofs. However, due to continuous system-level optimizations, this cost is largely negligible for the end user.

2. How to Obtain Gas (ETH)

• MetaMask Portfolio: As a flagship product of the ConsenSys suite, MetaMask’s native "Bridge" feature provides the most integrated and seamless experience for onboarding funds to Linea.

• Official Bridge (Linea Bridge): Use this for large transfers directly from Ethereum Mainnet. Note: Withdrawing funds back to L1 via the official bridge can take anywhere from a few hours to a full day while the final validity proof is generated.

• Third-Party Bridges: For speed, we recommend Orbiter or Owlto. These allow for near-instant "cross-L2" transfers (e.g., from Arbitrum or Base to Linea), bypassing the official bridge's waiting periods.

3. Optimization Tips

• Monitor L1 Congestion: Because Linea must eventually submit and verify zk-proofs on the Ethereum Mainnet, high gas prices on L1 can still indirectly inflate Linea's transaction fees.

• Batch Operations: Executing transactions through SlerfTools’ batch suite allows you to maximize the efficiency of zk-batching, further compressing the per-transaction cost compared to individual manual actions.

❓ Linea Exclusive FAQ

Why is the Linea network already in my MetaMask by default?

This is because Linea is developed by Consensys, the parent company of MetaMask. This native integration is a "factory default," meaning projects launched on Linea gain immediate exposure to tens of millions of MetaMask users. You won't need to guide your community through the friction of manually adding an RPC.

Both Linea and zkSync are zkEVMs; what is the difference?

The primary distinctions lie in EVM Equivalence and ecosystem backing:

• Linea: Focuses on being a Type 2 zkEVM, meaning it is almost 100% compatible with Ethereum. Developers can migrate code without any modifications. It also benefits from the massive user traffic funnel provided by MetaMask.

• zkSync: Employs a more aggressive technical architecture. While it may achieve higher TPS (Transactions Per Second), certain complex smart contracts may require re-compilation or minor adjustments to function correctly.

Why can't I trade my USDC on certain DEXs?

This is usually due to a mismatch between versions: you likely hold USDC.e (the bridged version) while the liquidity pool uses Native USDC, or vice versa.

• Fact: Circle has officially deployed Native USDC (0x1762...) on Linea.

• Pro Tip: We recommend using the MetaMask Swap feature. It automatically scouts the best routes and typically handles the liquidity for both USDC versions seamlessly.

Does Linea have a testnet?

Yes, it is called Linea Sepolia. For new developers, we strongly advise deploying and testing your contracts on Linea Sepolia for free. Once everything is verified, you can switch to the Mainnet with confidence.

Will using Batch Collection flag me as a "Sybil" (airdrop farmer)?

Risk Warning: Linea is notoriously strict regarding Sybil detection (as seen in their POH — Proof of Humanity program).

• Legitimate Use: If you are using the tool to consolidate capital for an actual project or business operation, it is safe.

• Airdrop Farming: If you are using it to farm points (e.g., Linea Voyage), frequent fund consolidation—especially patterns with clear on-chain correlations like "star-shaped" transfers—is highly likely to be flagged by their anti-Sybil systems.
