[Ethereum Foundation's Kohaku Releases SDK for Wallet-Level Privacy Integration] According to The Defiant, the Kohaku Initiative under the Ethereum Foundation has released a software development kit (SDK) that supports the 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 the 4337 mempool, allowing users to maintain autonomous control over their privacy without relying on centralized relays. The team has already implemented private transactions with 4337 mempool relay functionality, and integrations with Tornado Cash and Privacy Pools are currently under development. Kohaku aims to make end-to-end privacy the default option for Ethereum users by abstracting the complexity of interacting with privacy protocols.
