What is publicly visible on-chain?
Any transactions originating from or sent to an Ethereum account are visible in Ethereum explorers, including the Ethereum account address and information about the tokens involved. However, your Aztec private account address is never revealed in such transactions. Aztec private account activity takes place as transactions on the Aztec blockchain, as explained in our technical overview. Sends between Aztec private accounts reveal no public information. Ethereum vault deposits and withdrawals, initiated by your Aztec private account, have a Nyx relayer as the sender address and show token type and amount. Again, there is no visible link to your Aztec private account address. However, if you transfer 1.034567 ETH from your Ethereum account into your Aztec private account and shortly thereafter a Nyx relayer deposits 1.034567 ETH into an Ethereum vault, people may suspect that your Ethereum account is connected to the vault deposit. So, you may wish to wait a bit between these actions and/or break your deposit into multiple parts depending on the level of Nyx vault traffic at the time.
