The decentralized finance (DeFi) ecosystem continues to evolve at a rapid pace, and one of the most impactful developments in 2025 is 1inch’s integration of Uniswap’s Unichain. As a leading decentralized exchange (DEX) aggregator, 1inch has strengthened its cross-chain capabilities by incorporating Unichain’s high-performance blockchain infrastructure. This strategic move, announced on June 25, 2025, empowers users with faster transactions, improved security, and optimized swap rates—hallmarks of a mature and user-centric DeFi platform.
By supporting Unichain, 1inch expands its already extensive network coverage, which includes Ethereum, Solana, Optimism, Arbitrum, and Polygon. This integration is not just a technical upgrade—it’s a pivotal step toward seamless multi-chain interoperability, addressing one of the biggest challenges in today’s fragmented DeFi landscape.
What Unichain Brings to 1inch Users
The inclusion of Unichain within the 1inch ecosystem unlocks a suite of performance-driven advantages for traders, investors, and DeFi participants.
Lightning-Fast Transaction Speeds
Unichain’s architecture is engineered for speed, delivering sub-200ms transaction finality. For users, this means near-instant token swaps and reduced waiting times during high-volatility periods. In fast-moving markets, milliseconds matter—especially when arbitraging or reacting to breaking news. With Unichain, 1inch users gain a competitive edge through accelerated trade execution.
Advanced MEV Protection
Miner Extractable Value (MEV) remains a critical concern in decentralized trading. Unichain combats this through dual-layer protection: Trusted Execution Environment (TEE) technology and integration with 1inch’s proprietary Fusion solution. This combination prevents front-running and ensures that users receive the exact prices they expect—enhancing fairness and trust in every transaction.

Best-in-Class Swap Rates
Leveraging deep liquidity from Unichain’s pools—including Uniswap V2, V3, and V4—1inch now delivers some of the most competitive swap rates across the DeFi space. The platform’s smart routing algorithm evaluates multiple paths across chains and protocols to minimize slippage and maximize returns. Whether trading stablecoins or emerging altcoins, users benefit from optimized pricing powered by real-time liquidity aggregation.
Unified Asset Management
With full integration into the 1inch Portfolio dashboard and Wallet, users can now monitor and manage their Unichain-based assets alongside holdings on Ethereum, Arbitrum, Optimism, and other supported networks. This holistic view simplifies portfolio tracking, reduces the need for multiple tools, and streamlines tax reporting and performance analysis.
A Step Forward in Cross-Chain DeFi Interoperability
Sergej Kunz, co-founder of 1inch, highlighted the broader vision behind this integration: “Unichain aligns perfectly with our mission to create a seamless, multi-chain DeFi ecosystem. By combining Unichain’s high-speed swaps, deep liquidity, and built-in MEV protection with 1inch’s aggregation capabilities, we’re delivering unparalleled trading efficiency to our users.”
This sentiment reflects a growing industry trend—DeFi is no longer confined to single chains. Users demand fluid movement of capital across ecosystems without sacrificing speed or security. Platforms that enable this transition will lead the next phase of adoption.
The Unichain integration marks one of 1inch’s most significant upgrades since its expansion to Solana. It reinforces the platform’s role as a bridge between isolated blockchain environments, reducing friction and complexity for both retail traders and institutional participants.
Empowering Developers in the Multi-Chain Era
Beyond end-user benefits, this integration opens new doors for developers building within the DeFi space.
The 1inch Developer Portal now supports Unichain through dedicated APIs that allow developers to:
- Execute cross-chain token swaps
- Retrieve real-time wallet balances
- Query transaction history
- Integrate liquidity data into third-party applications
These tools enable builders to create innovative financial products—such as yield optimizers, portfolio trackers, and automated trading bots—that leverage Unichain’s speed and security while benefiting from 1inch’s aggregation intelligence.
For example, a developer could build a DeFi dashboard that pulls balance data across ten chains—including Unichain—and executes swaps via 1inch’s API to achieve optimal rates. Such applications were once technically complex; now, they’re within reach thanks to standardized developer tooling.

Why This Integration Matters for the Future of DeFi
As the number of active blockchains grows, so does the challenge of fragmentation. Users often face disjointed experiences: different wallets, separate interfaces, inconsistent gas fees, and delayed transactions. The 1inch-Unichain partnership directly addresses these pain points by offering a unified interface with consistent performance.
This integration underscores three core principles shaping modern DeFi:
- Speed: Sub-second transactions make DeFi feel more like centralized exchanges—without compromising decentralization.
- Security: Built-in MEV protection ensures users aren’t exploited by hidden arbitrage bots.
- Efficiency: Aggregation across deep liquidity pools minimizes slippage and maximizes returns.
Moreover, with over $832 million in liquidity now accessible via 1inch on Unichain, traders gain exposure to robust markets for major assets like WETH and USDC. This depth attracts more volume, creating a positive feedback loop that strengthens both ecosystems.
Frequently Asked Questions (FAQ)
Q: What is Unichain?
A: Unichain is a high-performance Layer 2 blockchain developed by Uniswap Labs. It's designed to offer fast, low-cost transactions with native MEV protection and seamless compatibility with existing Ethereum tools.
Q: Does this integration require me to use a new wallet?
A: No. You can continue using your existing Web3 wallet (e.g., MetaMask) with the 1inch app. Your Unichain assets will appear automatically in the 1inch Wallet and Portfolio dashboard once supported.
Q: How does MEV protection work on Unichain?
A: Unichain uses Trusted Execution Environment (TEE) technology combined with 1inch Fusion to prevent front-running. Orders are processed in private execution environments, ensuring no third party can exploit pending transactions.
Q: Can I provide liquidity on Unichain through 1inch?
A: While 1inch enables swapping and portfolio tracking on Unichain, direct liquidity provisioning must be done via Uniswap’s interface. However, you can monitor your LP positions through the 1inch Portfolio.
Q: Is there an additional fee for using Unichain via 1inch?
A: There are no extra platform fees. You only pay standard network gas fees on Unichain, which are typically lower than those on Ethereum mainnet.
Q: Which tokens are supported on Unichain via 1inch?
A: Major ERC-20 tokens like WETH, USDC, DAI, and UNI are fully supported. As Unichain expands its ecosystem, more tokens will be added automatically through 1inch’s dynamic token list.
