The 1inch Network has officially expanded its decentralized finance (DeFi) infrastructure to Base, the rapidly growing Ethereum Layer-2 (L2) scaling solution incubated by Coinbase. This strategic move enhances user access to deeper liquidity, reduced transaction fees, and faster swap execution—key advantages for both retail and advanced traders navigating the evolving DeFi landscape.
As part of this integration, both the 1inch Aggregation Protocol and the 1inch Limit Order Protocol are now live on Base. This deployment enables seamless cross-protocol token swaps across multiple decentralized exchanges (DEXs) operating within the Base ecosystem, all through the familiar 1inch interface.

Why Base Matters in the DeFi Ecosystem
Base is built as an Optimistic Rollup on Ethereum, designed to offer developers a secure, scalable, and cost-efficient environment for building decentralized applications. By inheriting Ethereum’s robust security model while significantly lowering gas costs and improving transaction throughput, Base has quickly become one of the most promising L2 networks in the crypto space.
Since its mainnet launch on August 9, Base has attracted over 100,000 daily active users, with transaction volumes rivaling those of established L2 platforms such as Optimism and Arbitrum. Its tight integration with Coinbase—allowing easy fiat on-ramps and access to millions of verified users—gives projects deployed on Base a unique advantage in user acquisition and real-world utility.
Sergej Kunz, co-founder of the 1inch Network, emphasized the alignment between 1inch and Base’s long-term vision:
“We are happy to expand to Base. It’s a very promising L2 solution, plus it’s incubated by such a major player as Coinbase. In addition, we totally share Base’s philosophy aimed at bringing the next billion users to blockchain.”
This synergy underscores a shared mission: democratizing access to decentralized financial tools and making blockchain technology more accessible, efficient, and user-friendly.
Enhanced Liquidity and Efficiency for 1inch Users
The deployment of 1inch on Base unlocks several tangible benefits for users:
- Lower Transaction Costs: Gas fees on Base are a fraction of those on Ethereum mainnet, enabling frequent or small-volume traders to operate more efficiently.
- Faster Swap Execution: With higher throughput and reduced network congestion, users experience quicker confirmation times.
- Aggregated Liquidity: 1inch’s smart routing algorithm scans multiple DEXs on Base to find the best possible price, minimizing slippage and maximizing returns.
By leveraging 1inch’s aggregation technology, users no longer need to manually compare prices across individual exchanges. Instead, they benefit from automated optimization across a wide range of integrated protocols.

Frequently Asked Questions (FAQ)
What is Base?
Base is an Ethereum Layer-2 scaling solution developed by Coinbase using Optimistic Rollup technology. It offers lower fees, faster transactions, and full EVM compatibility while maintaining Ethereum-level security.
Why did 1inch choose to expand to Base?
1inch expanded to Base due to its rapid user growth, strong backing from Coinbase, seamless fiat onboarding options, and alignment with 1inch’s mission to make DeFi more accessible and efficient for global users.
Are transaction fees really lower on Base?
Yes. As an L2 solution, Base processes transactions off the Ethereum mainnet and batches them for final settlement, resulting in significantly lower gas costs—often less than $0.01 per swap.
Can I use my existing wallet with 1inch on Base?
Absolutely. Most EVM-compatible wallets like MetaMask, Trust Wallet, and WalletConnect support Base. You just need to add the Base network configuration to your wallet.
Does 1inch support limit orders on Base?
Yes. The 1inch Limit Order Protocol v3 is fully deployed on Base, allowing users to place custom limit orders without relying on constant price monitoring or manual execution.
Is my funds’ security compromised when using L2s like Base?
No. Base inherits Ethereum’s security through cryptographic proofs and regular state commitments to the mainnet. While no system is entirely risk-free, Base follows rigorous auditing standards and leverages battle-tested rollup technology.
The Future of DeFi Across Layer-2 Networks
The expansion of 1inch to Base reflects a broader trend in DeFi: the migration toward scalable, user-centric Layer-2 ecosystems. As Ethereum continues to face congestion and high costs on its mainnet, L2 solutions like Base, Arbitrum, and Optimism are becoming essential infrastructure for sustainable growth.
By supporting multiple chains, 1inch reinforces its position as a universal gateway to DeFi—offering users consistent functionality, intelligent routing, and access to fragmented liquidity across networks.
This multi-chain strategy not only improves performance but also fosters greater inclusivity, allowing new users from traditional finance backgrounds (especially via Coinbase’s ecosystem) to enter DeFi with minimal friction.
