Kohaku, an Ethereum Foundation subsidiary, has released an SDK for wallet-level privacy integration.

According to Mars Finance, The Defiant reports that the Kohaku Initiative, a subsidiary of the Ethereum Foundation, has released a software development kit (SDK) that allows direct integration of privacy protocols such as Railgun, Tornado Cash, and Privacy Pools into wallet interfaces without intermediaries. This SDK enables all privacy protocol transactions to be routed through 4337 mempools, allowing users to control their privacy independently without relying on centralized relayers. The team has already implemented private transactions with 4337 mempool relay functionality, and integration with Tornado Cash and Privacy Pools is under development. Kohaku aims to make end-to-end privacy the default option for Ethereum users by abstracting the complexity of privacy protocol interactions. Developers have created CLI-based wallet demos, and wallets such as Ambire are being integrated, while a browser-based wallet extension is also under development. Kohaku is also developing support for post-quantum accounts, multi-signature, and hardware wallets.
