KuCoin Web3 Wallet on May 7 integrated the 1inch Swap API to enhance its trading infrastructure, enabling gasless swaps and MEV protection for more than 260 recently added tokenized real-world assets.
"The integration of the 1inch Swap API by KuCoin Web3 Wallet embodies what makes DeFi great," said Sergej Kunz, 1inch co-founder. "It combines their self-custody with our best-in-class liquidity infrastructure, giving users access to RWAs and enabling them to trade seamlessly with no gas or risk of MEV."
The integration routes user swaps through 1inch's aggregator, which pulls liquidity from a wide range of decentralized exchanges to offer users more competitive pricing. For eligible swaps, the API handles the gas cost, removing the need for users to hold native gas tokens. The infrastructure, which serves 26 million users with over $500 million in daily trades, also provides built-in protection against Maximal Extractable Value (MEV) attacks like front-running.
This move positions KuCoin’s wallet as a more direct competitor to traditional brokerage apps by reducing common on-chain friction. By integrating Ondo’s tokenized equities and then immediately improving the execution layer with 1inch, KuCoin is building a gateway for users to trade both crypto-native assets and tokenized securities with a more familiar, secure experience.
The integration directly builds on KuCoin Web3 Wallet’s late-April partnership with Ondo Global Markets. That deal brought over 260 tokenized U.S. stocks and ETFs—including exposures to Nvidia, Apple, and Tesla—into the self-custodial wallet. While the Ondo integration provided the assets, the 1inch API provides the execution layer, smoothing the process of entering and exiting those positions.
"As we continue expanding support for tokenized TradFi assets, we are helping users engage with onchain markets through a more secure and trusted wallet experience," said Gas Meng, Lead of KuCoin Web3 Wallet Operation.
The focus on security and user trust is critical as DeFi infrastructure matures. While 1inch’s core protocols were unaffected, a recent $6.7 million exploit at TrustedVolumes, an independent liquidity provider used by 1inch and other protocols, highlights the persistent risks in the ecosystem. Features like the MEV protection included in the 1inch API are designed to mitigate such risks at the transaction level, protecting users from value extraction and improving the overall quality of on-chain execution.
