The decentralized finance (DeFi) landscape continues to evolve at a rapid pace, and 1inch is at the forefront of this transformation. With the goal of delivering optimal trading experiences across multiple blockchains, 1inch has officially expanded its services to Linea, Consensys’ high-performance zkEVM Layer 2 network. This integration brings classic swaps, Fusion, and Fusion+ functionality to Linea, empowering users with enhanced liquidity, faster transactions, and significantly reduced costs.
This strategic move underscores 1inch’s commitment to broadening access to efficient, secure, and scalable DeFi solutions. By aligning with Linea—a network designed for Ethereum-equivalent performance with lower fees—1inch ensures that traders and developers alike can operate in a more seamless and cost-effective environment.
What Is Linea?
Linea is a zk-rollup Layer 2 scaling solution developed by Consensys, one of the most trusted names in the Ethereum ecosystem. Built as a zero-knowledge Ethereum Virtual Machine (zkEVM), Linea maintains full compatibility with Ethereum’s existing tooling, smart contracts, and developer workflows. This means dApps can migrate or deploy on Linea with minimal changes while benefiting from:
- Lower gas fees: Transactions are batched and proven off-chain, reducing congestion and cost.
- High throughput: Faster block times and efficient proof systems enable rapid execution.
- Strong security: Inherits Ethereum’s robust consensus and data availability guarantees.
- Developer-friendly tools: Full MetaMask integration, comprehensive SDKs, and detailed documentation streamline development.
With hundreds of active protocols already live on Linea—from lending platforms to NFT marketplaces—the ecosystem is rapidly maturing into a core hub for next-generation Web3 applications.
“In moving toward our mission to empower everyone to live on-chain, Linea’s approach has been to take web3 user, builder and community experience to higher levels,” Linea stated on its website. “With innovations in security, digital identity, payments, and DeFi, as well as community nurturing and organization, we’ve aimed to lower barriers to entry, create the most secure environment, streamline everyday processes, and elevate the whole Web3 experience.”

Why This Expansion Matters for DeFi Users
The expansion isn’t just technical—it’s transformative for real-world usability. Here’s why:
Lower Transaction Costs
Ethereum mainnet fees can be prohibitive for small trades. On Linea, users enjoy dramatically reduced gas costs, making micro-transactions viable and frequent trading more economical.
Faster Settlement Times
Thanks to zk-rollup architecture, confirmations are near-instantaneous during normal network conditions. This improves trade execution speed and reduces exposure to market volatility during pending transactions.
Seamless User Experience
Because Linea is EVM-equivalent, wallets like MetaMask work out of the box. There's no steep learning curve—users connect their wallets just as they would on Ethereum or Polygon.
Broader Liquidity Access
By aggregating liquidity from multiple sources across Linea, 1inch minimizes slippage and maximizes output. Whether you're swapping stablecoins or emerging altcoins, the system finds the most efficient route.
