According to CoinMeta, the Ethereum Foundation stated that in light of multiple hacker attacks and security vulnerabilities that have occurred over the past week, privacy and security should not be viewed as separate goals. When wallets come with privacy protection features by default, it becomes more difficult for attackers to exploit users' on-chain transaction histories to carry out attacks. The privacy tool kohaku claims that its SDK is gradually maturing and has integrated privacy protocols such as tornado, cash, railgun, privacy, and pools.
