[Ethereum Foundation Kohaku Launches Wallet Privacy Integration SDK, Supporting Ethereum Wallet Integration with Protocols Like Railgun] Deep Tide TechFlow reports that on May 26, according to The Defiant, the Ethereum Foundation's Kohaku Initiative released an SDK designed to integrate privacy protocols into Ethereum wallets. The SDK has now implemented a functional 4337 mempool relay in version v0.0.1-alpha.21 of the kohaku-eth/railgun integration, enabling private transactions. The SDK aims to integrate shielded pool protocols such as Railgun, Tornado Cash, and Privacy Pools into wallet interfaces, reducing reliance on centralized relay infrastructure. Kohaku also showcased a CLI-based wallet and is advancing integration with production-grade wallets like Ambire, while developing features such as post-quantum accounts, multi-signature support, and hardware wallet compatibility.
