Ethereum Foundation’s Kohaku Launches Wallet Privacy Integration SDK, Enabling Ethereum Wallets to Integrate Protocols Such as Railgun
According to The Defiant, the Ethereum Foundation’s Kohaku Initiative has released an SDK for integrating privacy protocols into Ethereum wallets. A functional 4337 mempool relay supporting private transactions is now available in version v0.0.1-alpha.21 of the kohaku-eth/railgun integration. This SDK aims to integrate shielded-pool protocols—such as Railgun, Tornado Cash, and Privacy Pools—directly into wallet interfaces, reducing reliance on centralized relay infrastructure. Kohaku has also demonstrated a CLI-based wallet and is advancing integration with production-grade wallets like Ambire, while simultaneously developing post-quantum accounts, multisig support, and hardware wallet compatibility.
