Key Takeaways
- Vitalik Buterin has backed Kohaku’s per- dapp address feature, calling single global addresses a “norm we have to break” for Ethereum privacy.
- Kohaku’s v0.0.1-alpha.21 release made ERC-4337 relaying operational for Railgun transactions, reducing reliance on protocol-specific privacy infrastructure.
- Ethereum’s Kohaku, EIP-8250, and account abstraction upgrades are scheduled for the Hegotá hard fork in H2 2026.
Why Single Addresses Are a Privacy Problem
Most Ethereum users today interact with the network through a single persistent wallet address, a model that allows anyone to trace every token held, every protocol used, and every transaction made by a given user simply by querying public blockchain data.
Kohaku, an open-source privacy initiative backed by the Ethereum Foundation, is designed to close that gap by giving wallet developers modular tools to implement shielded transaction pools and private query infrastructure into existing wallets without requiring users to navigate separate privacy protocols.
The per- dapp address feature, highlighted by Buterin on May 27 and credited to contributors kassandraETH and ncsgy, takes a direct approach to the metadata leakage problem so that each time a user connects to a new application, the wallet automatically generates a fresh address.

This breaks the onchain link between a user’s activity on a decentralized exchange ( DEX), a lending protocol, and any other dapp they interact with, making it substantially harder for data aggregators or surveillance infrastructure to build a complete financial profile of a given user.
Kohaku’s endgame is much more ambitious, having already integrated with established Ethereum privacy tools, including Railgun and Privacy Pools, abstracting away their technical complexity so that ordinary users can access shielded transactions through their regular wallets.
