Casa, a private key manager, has launched a transaction relay feature for its Ethereum 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 feature 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. Users will need to cover gas fees with their Pay Wallet, but in return, they can avoid their on-chain ETH addresses being connected to Casa.
