Use a synced passkey or enroll a backup passkey
Your passkey encrypts and decrypts your private address. If you lose your passkey, you can’t view or use your private funds. To protect your ownership of your funds, we have no way of recovering your passkey. So, please back up your passkey by doing one of the following:- Use a synced passkey (iCloud Keychain, Google Password Manager, etc)
- Create a second passkey on another device.
Common questions
Why do I have to claim the funds I deposit into my private address?
To protect your privacy. If your private address was included in your deposit transaction on Ethereum, these two addresess would be publicly linked. The use of a claim secret prevents this linkage. Our app automatically manages the secret in your browser so you don’t need to remember it when you initiate the claim transaction. We also give you the chance to back it up during the deposit flow for extra redundancy if you wish.Why do I have to share my address for a private send?
The recipient must add your private address to their contact list in order to discover the private send from your address and decrypt the transaction details.What is publicly visible onchain?
In short, any transactions originating from or destined to your public address are visible on Ethereum, including your public address and information about the tokens involved. However, your private address is never revealed in such transactions. Ethereum vault deposits and withdrawals, initiated by your private address, have a Nyx relayer as the sender address and show token type and amount. For more detail about specific actions, see the table below. Note that private address activity takes place as transactions on the Aztec blockchain, as explained in our technical overview.| Action | Publicly-visible on Aztec | Publicly-visible on Ethereum |
|---|---|---|
| Transfer from Ethereum to your private address. | Information about the tokens involved. No Aztec address is revealed. | Your Ethereum address and information about the tokens involved. |
| Send tokens from one private address to another. | Nothing. Only the other party knows what happened. | N/A |
| Deposit into an Ethereum vault from your private address. | Information about the tokens involved. No Aztec address is revealed. | Nyx relayer as sender for a transaction that deposits publicly visible token type and amount into a vault contract. So, if you transfer 1.034567 ETH into your private address and shortly thereafter a Nyx relayer deposits 1.034567 ETH into an Ethereum vault, people will suspect your Ethereum address is connected to the deposit. |
| Redeem shares in an Ethereum vault. | Information about the tokens involved. No Aztec address is revealed. | Nyx relayer as sender for a transaction that redeems shares for a publicly visible token type and amount. |
| Transfer from your private address to your Ethereum address. | Information about the tokens involved. No Aztec address is revealed. | Your Ethereum address and information about the tokens involved. |
