1inch Integrates Unichain Network
1inch has revealed its collaboration with the Unichain network, aiming to enhance secure swap opportunities at competitive rates, marking a significant advancement in the mission to unify decentralized finance (DeFi).
Overview of 1inch
1inch stands out as a prominent DeFi aggregator, dedicated to promoting permissionless cryptocurrency trading. The platform has gained significant traction, boasting 23 million users and a daily trading volume of approximately $1 billion, thanks to its efficient and cost-effective token exchange services. It also provides an array of tools, such as a self-custodial wallet, a digital asset portfolio tracker, a developer portal, and a debit card that simplifies crypto spending. The overarching goal of 1inch is to make the DeFi experience accessible and user-friendly for everyone.
Understanding Unichain
Unichain serves as the DeFi chain associated with Uniswap, specifically designed to facilitate nearly instantaneous transactions at minimal costs. As a Layer-2 solution on Ethereum, it utilizes optimistic rollup technology to achieve faster and cheaper transactions while ensuring full compatibility with the Ethereum ecosystem. Launched in December 2024, Unichain has already amassed a total value locked (TVL) in DeFi nearing $850 million. In contrast, Uniswap, which debuted in 2018, gained significant popularity in the latter half of 2020 and currently holds a TVL of nearly $4.8 billion, making it one of the leading decentralized exchanges (DEX) in operation.
1inch’s Integration with Unichain
With a DeFi TVL exceeding $4 billion, 1inch supports over 12 different blockchains, including Ethereum, Arbitrum, Base, and BNB, and now incorporates Unichain into its ecosystem. This integration is accessible via the 1inch dApp, 1inch Wallet, and 1inch APIs, enabling swaps at optimal rates across various chains. Users can benefit from double MEV (maximal extractable value) protection, access to high liquidity, and efficient transactions with sub-block latency of 200 milliseconds through optimistic rollup technology. Additionally, 1inch now offers the ability to directly exchange Unichain tokens on the network and seamlessly transfer liquidity between Unichain and other EVM-compatible blockchains. Users can also securely store and monitor their Unichain assets using 1inch Wallet and 1inch Portfolio, which now provides real-time visibility of Uniswap balances.
Additional Features
Unichain has notably experienced substantial trading volumes in stablecoins. From March to June 2025, the market capitalization of stablecoins on Unichain surged to $344.2 million, with over half of that amount being issued natively on the network. Furthermore, the integration extends to the 1inch developer portal, allowing developers and partners to access Unichain through various 1inch APIs, including Swap (Fusion, Fusion+, Classic Swap, Orderbook), Balance, Spot Price, and History. The protocols supported on Unichain via 1inch include WETH, Uniswap V2, Uniswap V3, and Uniswap V4. Sergej Kunz, co-founder of 1inch, commented on the integration, stating, “Unichain aligns perfectly with our vision of an entirely integrated cross-chain DeFi. With near-instant swaps, native MEV protection, and Unichain’s deep liquidity available through 1inch, we are pushing the boundaries of multi-chain trading while providing users with the best execution across all ecosystems on a single platform.”
