1inch, a leading DeFi aggregator, has announced the full integration of the Unichain network – a second-layer solution based on OP Stack, allowing users to swap tokens on favorable terms and access advanced features of the DeFi ecosystem.

New Features for 1inch Users
From now on, the Unichain network is available to 1inch users through the 1inch dApp, the 1inch Wallet mobile app, and the project’s API. The integration enables token swaps with advantageous rates across more than 12 networks, double protection against MEV bots, and access to additional liquidity. Balances and positions on Uniswap can be viewed in real-time in the 1inch Wallet and 1inch Portfolio.
The 1inch developers emphasized that the inclusion of Unichain in the list of supported networks allows for:
- the most favorable rate for token swaps both within a single network and across networks;
- fast transactions thanks to sub-blocks with a processing time of 200 milliseconds and OP Stack technology;
- double protection against MEV bots through 1inch’s Fusion solution and the application of TEE from Unichain during block formation;
- full support in the 1inch Wallet and aggregator API;
- real-time balance display on Uniswap in the 1inch Portfolio.
Advantages of the Unichain Network for DeFi
Unichain is a second-layer network, with its main network launch occurring in February 2025. It is built on OP Stack and fully compatible with the Ethereum ecosystem. As a result, users benefit from faster and cheaper transactions without sacrificing functionality or security.
As of mid-June 2025, the total value locked (TVL) in Unichain reached $832 million, providing 1inch users access to significant liquidity.
“Unichain perfectly fits into our concept of a fully integrated, cross-chain DeFi infrastructure,” said Sergey Kuntz, co-founder of 1inch. “Instant exchanges, native MEV protection, and the deep liquidity of Unichain, now available through 1inch, allow us to push the boundaries of cross-chain trading. We provide users with the best execution of trades on a single platform.”
Enhanced Opportunities for Traders and Developers
The integration opens new options for 1inch users:
- token swaps within the Unichain network or between it and other EVM-compatible networks at the most favorable rates;
- convenient storage and management of assets through the 1inch Wallet and 1inch Portfolio;
- automatic protection against MEV attacks, including additional protection using TEE in Unichain.
Unichain stands out with high activity in the stablecoin sector – from March to June 2025, the total market capitalization of stablecoins in the network grew to $344.2 million, more than half of which was issued directly in Unichain. This indicates the trust of professional traders in the network and the low fees that make frequent transactions profitable.
The 1inch Developer Portal platform also supports integration with Unichain via API, giving developers access to features such as Fusion, Fusion+, order books, and other capabilities.
Support for Key DeFi Protocols
With the integration, 1inch now supports solutions in the Unichain network such as WETH, Uniswap V2, Uniswap V3, and Uniswap V4. This strengthens 1inch’s position as a leading aggregator that unites various DeFi ecosystems on a single platform. Token swaps through Unichain and over 12 other networks are already available to users in the 1inch app.
