KuCoin Web3 Wallet has integrated the 1inch Swap API, enabling gasless swaps and MEV protection for users trading crypto assets and tokenized real-world assets (RWAs) directly in the wallet.
The move builds on the wallet’s earlier partnership with Ondo Global Markets, which added tokenized RWA exposures to its self-custodial platform. The 1inch integration focuses on improving the execution layer for swaps.
With this integration, users will be able to perform swaps without needing to hold native gas tokens. The API also provides access to aggregated liquidity, potentially tighter pricing, and safeguards against front-running and sandwich attacks.
As tokenized RWAs gain traction across blockchains, execution quality and security have become central concerns for broader adoption. The integration aims to reduce several common pain points in decentralized trading, including liquidity fragmentation and MEV risks.
In a release shared with The Crypto Times, Gas Meng, lead of KuCoin Web3 Wallet operations, said the integration supports the wallet’s goal of making self-custody more practical while maintaining security and execution standards.
“With the integration of the 1inch Swap API, we are able to provide a smoother swap experience backed by better pricing, deeper liquidity, gasless execution, and MEV protection,” Meng emphasized. “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.”
“The integration of the 1inch Swap API by KuCoin Web3 Wallet embodies what makes DeFi great,” said Sergej Kunz, co-founder of 1inch. “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 need for gasless and MEV-protected trades
Onchain trading has long been hampered by several persistent frictions that discourage wider participation, particularly among users entering the space through tokenized real-world assets.
One major obstacle is the requirement to hold native blockchain gas tokens simply to execute a transaction. This adds complexity and cost for new users who may not want to manage multiple token balances.
At the same time, liquidity across decentralized exchanges remains fragmented, often resulting in higher slippage and less favorable pricing during swaps.
Beyond these usability issues, security risks tied to Maximal Extractable Value (MEV) have become a growing concern. Front-running and sandwich attacks allow sophisticated actors to exploit pending transactions, effectively extracting value at the expense of regular users.
As tokenized RWAs bring more traditional finance participants onchain, addressing these problems has become essential. Without gasless options and MEV protection, many potential users may remain hesitant to engage directly with decentralized markets, limiting broader adoption of onchain financial products.
KuCoin Web3 Wallet indicated it will continue developing its in-wallet trading tools as part of a longer-term effort to serve as a comprehensive platform for both crypto and tokenized traditional finance assets. No specific timeline for additional features was provided.
