Zingo! A private wallet and financial insight provider.

Use zero knowledge cryptography to manage your transaction history, in a private and mindful way.

Take exclusive and unique control of your financial history. Use this unique insight into your own financial behavior, to introspect on how you spend money. Share insights on your terms. Establish healthy relationships with diverse economic communities.

Only you have the power to share your information! Your perspective matters. You matter.

When you send Zcash you can write a memo containing anything you like. When you receive Zcash you also receive the memo that the Sender wrote. As with most cryptocurrencies, wallets routinely send transactions to themselves to recover "change" from the transaction. In this case, where the application is both the Sender and the Receiver, Zingo uses the memo system to write notes to itself about the transactions it builds for the User.

Zingo extracts that data to provide insights exclusively to you. In our initial release we already use this introspective mechanism to "remember" which full Unified Addresses you've previously sent Zcash. In other words, Zingo keeps track of who you've sent Zcash to, on the blockchain. This "Address Book" of people you've "Sent To" in the past is completely private and, as long as you properly protect your seed-phrase, will be fully recovered even if you lose your device.

We're currently implementing another use of these on-chain memos, that will allow you to keep track (even if you lose your device) of which addresses you previously produced to receive funds at. That is, you'll always have a full list of all the addresses you asked people to use to send you zcash.

Taken together these two introspective mechanisms provide you with insight into who you've sent funds to, and who you've asked for funds from.

Your on-chain transaction details are never exposed to any third party. By providing you with private insight into your own economic behavior, we are enabling everyone to make healthier financial decisions.

Technical Detail of UA Caching:

Zcash supports a multi-protocol Unified Address that enables the protocol to upgrade to newer versions without breaking backwards compatibility with earlier versions. This Unified Address system is implemented by clients off-chain. Clients share Unified Addresses with each other, the Unified Addresses contain Protocol Version Specific Addresses that the client can unpack, and publish to the blockchain as part of the transaction that it builds. This means that the on-chain address associated with a transaction does not contain all of the information the Sending-Client received as a "Unified Address" from the Recipient-Client, off-chain. If the Sending-Client simply recorded the UA off-chain then, in the case of Re-Sprouting the Client from its SeedPhrase, there'd be no way to recover that relationship data. Zingo solves this issue by recording the original recipient provided UA in the memo field of change from the transaction.
