Casa, a private key manager, has launched a transaction relay feature for its Ethereum (ETH) vaults to provide users with more privacy when transacting. The company introduced a mechanism that allows users to use an ETH Pay Wallet as a relay to create and transact from their vaults. This new functionality aims to offer enhanced on-chain privacy by ensuring that gas fees and transactions sent from the ETH Pay Wallet are not associated with Casa on-chain. However, it is important to note that all on-chain activity will still be viewable, and the ETH Pay Wallet does not provide anonymity through obfuscation tools. Users will need to cover gas fees with their Pay Wallet, but in return, they can avoid connecting their on-chain ETH addresses to Casa.
