Layer2 Star Project Linea Mainnet Guide

6 min readSep 6, 2023

Linea has officially launched its mainnet, marking a new phase in the project’s development. As a star project in the Layer2 space, what outstanding advantages does Linea have? This article comprehensively explores key information about Linea’s project positioning, operation mechanism, and ecosystem layout.

I. Project Introduction

Linea, formerly known as ConsenSys zkEVM, is a Layer2 network for the Ethereum Virtual Machine (EVM) using zero-knowledge technology. It boasts several advantages, including extremely low gas fees, comprehensive support for existing Ethereum wallets and infrastructure, high security (with over 500,000 verification nodes), and a leading position in zk-proofs.

ConsenSys zkEVM launched its testnet in December last year and achieved 1.5 million transactions within the first few weeks after three months of operation. On March 28, 2023, the ConsenSys zkEVM testnet officially launched as Linea. Developers can continue to use familiar tools like MetaMask, Truffle, and Infura to deploy and manage applications without changing code or rewriting smart contracts. Linea allows builders to create scalable DApps or migrate existing ones without code changes.

MetaMask, the popular wallet from the same parent company as Linea, ConsenSys, adds to Linea’s strong competitive position in the Ethereum Layer2 space, harnessing network effects.

The Linea mainnet’s ecosystem is rich, covering various dimensions, including cross-chain bridges, NFTs, wallets, DeFi, social, and more. Achieving complete ecosystem interoperability is not an easy task. Our goal is to complete interactions with the lowest cost and maximum efficiency to access as many airdrop opportunities as possible.

II. Mainnet Launch

In July 2023, Linea’s mainnet was officially launched, marking the project’s transition from the testing phase to commercial operation. The mainnet’s launch solidified Linea as a highly regarded choice in the Ethereum Layer2 solutions. The mainnet’s deployment also fueled the robust development of Linea’s ecosystem. On Linea, projects from various domains such as DeFi, NFTs, cross-chain, and more were launched, providing users with diverse application scenarios and opportunities. These initiatives further solidified Linea’s position in the Ethereum Layer2 ecosystem.

III. Ecosystem Layout

The Linea ecosystem comprises several key components:

- Cross-Rollup Bridges: Owlto, Symbiosis, and others support asset cross-rollup transfers.
- NFT Platforms: Zonic, Omnisea, and others for NFT creation and trading.
- DeFi Applications: LineaBank, Velocore, and various other projects in the DeFi space.
- Wallets: Fluvi, MetaMask, and other wallets integrated with Linea.
- Social Applications: IDriss, Atticc, supporting account tipping and NFT trading.
- Domain Services: Linea Name Service, and more.

IV. User Interactions

After the mainnet launch, users can interact with Linea in the following ways:

After connecting your wallet, enter the amount you want to cross-chain and confirm it in your wallet to complete the fund transfer.

Use Owlto for cross-Rollup transfers.

Owlto currently supports networks such as Ethereum, zkSync, Arbitrum, Arbitrum Nova, Optimism, Polygon zkEVM, BNB Chain, opBNB, Zora, Base, and will support Starknet, ZetaChain, Immutable X, and more in the future. With the fastest cross-chain speed, taking only 20 seconds, and the lowest fees, using Owlto for cross-chain needs is highly recommended.

Owlto also has a unique referral mechanism that allows you to earn some ETH rewards by inviting friends, and points are likely to be a standard for future airdrops.

- Velocore Dex: A DEX based on the Velodrome code, also a DEX with a higher TVL on zkSync Era.
- WOOFi: Launched by WOO Network, WOOFi uses a new on-chain market-making algorithm called sPMM, which better simulates the price, spread, and depth of centralized trading platforms.
- zkUSD: Combining collateralized stablecoins with zkSNARKs technology, the next-generation DeFi platform focuses on privacy, stability, and cross-chain interoperability in transactions.
- EchoDEX: The first DEX on the Linea network, known for its low-cost transactions and liquidity aggregation features, with a simple interface and high security.


- IDriss: A Web3 social application plugin that allows users to conduct transfer transactions on Twitter with others who have installed the same plugin. After sending a transaction request, users need to confirm the transfer on their plugin wallet, such as MetaMask.

- Linea Name Service: A third-party domain name project within the Linea ecosystem, already live on the Linea mainnet.

V. Future Outlook

As a leading Layer2 project, Linea has a solid foundation in both technology and commercialization. With the operation of the mainnet, its ecosystem will continue to expand, and the user base will grow steadily.

As Ethereum evolves into a multi-layered architecture, Linea has the opportunity to become a high-speed channel connecting the Ethereum base chain and application chains, securing its position in the scaling solution landscape.”
