The decentralized finance (DeFi) landscape continues to evolve at breakneck speed—and one of the most significant developments in 2025 is the integration of Unichain into the 1inch ecosystem. This strategic move brings powerful new capabilities to users, developers, and the broader DeFi community by combining cutting-edge blockchain infrastructure with advanced swap optimization.
Now, Unichain is fully accessible across the 1inch dApp, 1inch Wallet, and 1inch APIs—unlocking seamless, secure, and ultra-efficient token swaps with top-tier liquidity and enhanced protection against MEV (Miner Extractable Value). This integration marks a major milestone in the ongoing effort to unify fragmented DeFi networks into a cohesive, user-first financial ecosystem.

What You Gain from the 1inch x Unichain Integration
With this partnership, 1inch users gain immediate access to a high-performance Layer-2 network designed for speed, scalability, and Ethereum compatibility. Whether you're swapping tokens, managing portfolios, or building decentralized applications, the benefits are substantial:
- Best-in-class swap rates across Unichain and more than 12 other EVM-compatible blockchains
- Lightning-fast transactions powered by 1-second sub-blocks and optimistic rollup technology
- Double-layer MEV protection: 1inch’s intent-based routing combined with Unichain’s TEE (Trusted Execution Environment) block-building
- Comprehensive tooling support via 1inch Wallet, Portfolio tracker, and developer APIs
- Real-time visibility into Uniswap positions and balances through the 1inch Portfolio dashboard
This isn’t just another network addition—it’s a leap forward in making DeFi faster, safer, and more accessible to everyone.
Why Unichain Stands Out in 2025
Launched in early 2025, Unichain has rapidly emerged as one of the most promising Layer-2 solutions in the Ethereum ecosystem. Built using optimistic rollup architecture, it delivers near-instant transaction finality while drastically reducing gas costs—without sacrificing security or developer experience.
Its full EVM equivalence means that existing Ethereum dApps can migrate with minimal changes, accelerating adoption across protocols and users alike. By mid-June 2025, Unichain’s Total Value Locked (TVL) had reached an impressive $832 million (source: DeFiLlama), reflecting strong confidence from both retail and institutional participants.
That growing liquidity pool is now seamlessly integrated into 1inch’s aggregation engine, ensuring users always get optimal pricing when trading on or across Unichain.
How 1inch Users Benefit
For traders and investors, the integration unlocks several key advantages:
Swap Tokens with Maximum Efficiency
You can now swap native Unichain tokens directly on the network—or bridge assets between Unichain and other chains like Ethereum, Arbitrum, or Base—with confidence that you’re getting the best available rate. The 1inch aggregator scans dozens of liquidity sources in real time, minimizing slippage and maximizing returns.
Track All Your Assets in One Place
Using 1inch Wallet and 1inch Portfolio, you can securely store, manage, and monitor your Unichain-based assets alongside holdings from other networks. Notably, all Uniswap V2, V3, and upcoming V4 positions on Unichain are automatically synced to your Portfolio dashboard, giving you a unified view of your DeFi activity.
No more juggling multiple tabs or apps—your entire portfolio is visible at a glance.
Enhanced Security Through Dual MEV Protection
One of the standout features of this integration is the dual-layer defense against MEV attacks:
- 1inch’s intent-based swap protocol ensures your trade intentions are executed fairly, shielding you from front-running bots.
- Unichain’s TEE-based block-building adds a hardware-secured layer that prevents validators from manipulating transaction order.
Together, these technologies create one of the most robust anti-MEV environments in DeFi today—critical for preserving trade integrity and user trust.

Strong Stablecoin Adoption on Unichain
Stablecoins are the lifeblood of DeFi—and Unichain has seen explosive growth in this category. Between March and June 2025, the total stablecoin market cap on Unichain surged to $344.2 million, with over 51% issued natively on the network.
This shift toward native issuance signals increasing confidence in Unichain’s infrastructure. Low transaction fees and fast settlement make it ideal for frequent traders, payment systems, and yield strategies that rely on stable assets.
For 1inch users, this means deeper liquidity pools for stablecoin swaps—leading to tighter spreads and better execution, especially for large-volume trades.
Empowering Developers and Builders
The integration extends beyond end-users. The 1inch Developer Portal now supports Unichain via its full suite of APIs, enabling builders to incorporate advanced DeFi functionality into their applications.
Available endpoints include:
- Swap API: Access Fusion, Fusion+, Classic Swap, and Orderbook modes
- Balance API: Retrieve real-time asset balances
- Spot Price API: Get accurate price quotes across liquidity sources
- History API: Track past transactions and user activity
These tools empower developers to build cross-chain wallets, trading bots, analytics dashboards, and more—leveraging Unichain’s speed and 1inch’s aggregation intelligence.
Whether you're launching a new dApp or enhancing an existing platform, integrating with 1inch on Unichain simplifies access to deep liquidity and optimized execution.
Supported Protocols on Unichain via 1inch
Currently supported protocols include:
- WETH (Wrapped Ether on Unichain)
- Uniswap V2
- Uniswap V3
- Uniswap V4 (beta)
As more protocols deploy on Unichain, 1inch will continue expanding support—ensuring users always have access to the latest DeFi innovations.
FAQ: Your Questions About 1inch & Unichain Answered
Q: What is Unichain?
A: Unichain is a Layer-2 blockchain built on optimistic rollup technology. It offers fast, low-cost transactions while maintaining full compatibility with Ethereum smart contracts and tools.
Q: Can I swap tokens between Unichain and other blockchains using 1inch?
A: Yes! 1inch supports cross-chain swaps between Unichain and over 12 other EVM-compatible networks, ensuring seamless asset movement with optimal pricing.
