Kassandra, a researcher at the Ethereum Foundation, outlined what the team is shipping for Kohaku, an open-source initiative for designing secure and private wallets on Ethereum. Kohaku's mission is to make end-to-end privacy as the default for all Ethereum users, while minimizing reliance on trusted third parties. The immediate priority is embedding shielded pool protocols, such as Tornado Cash, Railgun, and Privacy Pools, directly into wallets via a wallet SDK. Kassandra added that a bigger unlock will be routing all private transactions through the ERC-4337 mempool using EIP-7702, eliminating reliance on specific relayers. The Kohaku SDK is available in alpha. An experimental browser extension wallet is also in the works. Kassandra is also building a CLI wallet that uses the SDK directly, with a showcase planned for Berlin Blockchain Week. Kohaku is one of the three CROPS-aligned technical north stars Vitalik Buterin named earlier today alongside FOCIL and EIP-8141 in his outline of where the Ethereum Foundation is heading. Sponsored byETHConf lands in NYC June 8-10, bringing together 5,000+ attendees, 150+ speakers, and 100+ companies across Ethereum, stablecoins, and institutional adoption.
