PANews reported on May 26th that, according to The Defiant, the Kohaku Initiative, a subsidiary of the Ethereum Foundation, has released a software development kit (SDK) that allows privacy protocols such as Railgun, Tornado Cash, and Privacy Pools to be directly integrated into wallet interfaces without intermediaries. This SDK enables all privacy protocol transactions to be routed through the 4337 mempool, allowing users to control their privacy independently without relying on centralized relayers.

The team has implemented private transactions with 4337 mempool relay functionality, and integrations with Tornado Cash and Privacy Pools are 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 post-quantum accounts, multi-signature, and hardware wallet support.
