Decentralized finance just got an upgrade with 1inch; a leading Defi aggregator has launched the Unichain Network, bringing the scope and efficiency of DeFi multi-chain swaps for users and developers alike.
In Brief
- Multi-chain swaps via 1inch and Unichain enable instant, low-cost cross-chain trading with $832M TVL and robust MEV protection.
- Intent-based models and Unichain’s TEEs ensure fair transaction ordering, reducing slippage and front-running risks for DeFi users.
- Developers gain full-stack access to Unichain’s protocols (Uniswap V2–V4) via 1inch APIs, accelerating ecosystem growth.
The bridge is finally established between Unichain’s high-performance Layer-2 infrastructure and 1inch’s vast assets like its dApp ecosystem, its 1inch Wallet and Apis.
This partnership delivers a compelling suite of benefits focused on securing the best rates, minimizing cost and maximizing user control.
Why This Integration Matters for Cross-Chain Trading
The core promise of the Unichain integration is access to an Optimistic Rollup-based Layer-2 network designed for speed and cost-efficiency while maintaining Ethereum compatibility.
The platform, launched in February 2025, has witnessed rapid adoption given its metrics; by mid-June 2025, Unichain boasted a Total Value Locked of $832 million, according to DeFi Lama.
Additionally, this deep liquidity pool is now seamlessly accessible through all 1inch interfaces.
Sergej Kunz, co-founder of 1inch, emphasized the strategic fit:
“Unichain fits perfectly into our vision of a fully integrated, cross-chain DeFi. With near-instant swaps, native MEV protection and deep Unichain liquidity now accessible via 1inch, we’re pushing the boundaries of what’s possible in multi-chain swaps. We’re providing users with the best execution across ecosystems, all in one convenient location.”
New capabilities enabled through the integration
With the new update, new features and updates are sure to warm the hearts of each user.
Unlocking Top Swap Rates & Efficiency
For instance, superior swap rates of Unichain tokens.
Whether users are swapping tokens directly on the Unichain network or orchestrating complex cross-chain trades involving Unichain and over a dozen other supported networks, 1inch’s aggregation engine scours all available liquidity sources to find the most optimum choice.
Real-Time Tracking: Unified Portfolio Visibility
Going beyond executing, these new updates elegantly solve managing assets across numerous chains.
Unichain users have access to a new and improved 1inch portfolio, which offers automatic, real-time tracking of Uniswap balances and positions held on Unchain.

This means users gain a consolidated, up-to-the-minute overview of their entire Unichain holding directly within the familiar 1inch portfolio dashboard.
This new update positions 1inch as a leading contender for the best DeFi aggregator of Uniswap tracking, especially concerning Layer-2 security.
Enhanced Security: Double-Layered MEV Protection
Maximal Extractable Value (MEV) represents a significant concern for traders, potentially leading to front-running, sandwich attacks, and value extraction that harms the end user.
Taking this into account, the platform has set inherent mechanisms protecting its key features, such as its intent-based and cross-chain Unichain swaps on 1inch.
For those not unaware, intent-based models allow users to define their desired outcome(e.g., “Receive at least X token Y for my token Z”) without revealing the exact path or pricing details upfront.
This also doubles up the security offered by Unichain’s Trusted Execution Environments (TEEs) block building.
The mechanisms ensure fair transaction ordering, mitigating any opportunities for MEV extraction at the network level.
This combined approach offers robust MEV protection explained for traders as a core feature, significantly reducing the risks of unnecessary slippage and unfair value extraction during transactions.
Stablecoins: A Cornerstone of Unichain’s Liquidity
Stablecoins are a prime future for DeFi, and Unchain has seen big volumes.
Data from DeFiLama revealed a surge in Unichain’s total stablecoin market cap, reaching $344.2 million between March and June 2025.
It also unveils that 51% of this value comes from stablecoins issued natively on Unichain itself. Its network’s credible support is a green light for serious trading activities.

Developers can now access Unichain via 1inch APIs, including:
- Swap (Fusion, Fusion+, Classic Swap, Orderbook)
- Balance
- Spot Price
- History
Currently, the supported protocols on Unichain via 1inch are:
A Unified Step Forward for DeFi
Multi-chain swaps are like gold to any trader within the space. With Unichain integrating into a leading DeFi platform like 1inch, it’s sure to spark some interest within the space.
The former offers its high-speed, stablecoin support and low-fee Layer 2 swap infrastructure.
