Vitalik Buterin Backs Kohaku Per-Dapp Addresses to Advance Ethereum Privacy

On May 27, 2026, Vitalik Buterin endorsed Kohaku’s per-dapp address feature, marking the latest step in Ethereum’s privacy push. The story began May 25 with the Ethereum Foundation’s release of the Kohaku SDK, which packages over 50 PSE projects and adds live ERC-4337 Railgun support. On May 26, Buterin urged immediate deployment of privacy tools while Aztec unveiled its four-layer programmable privacy stack with 3,500+ sequencers. The May 27 kohaku-eth/railgun v0.0.1-alpha.21 update made shielded transactions operational ahead of the H2 2026 Hegotá hard fork. ETH traded at $2,080.62, down 1.72%.
