Check what you were given.
A Loch user can hand you three things: a receipt for one payment, a report on where a withdrawal came from, or a viewing key. Paste it here. The check runs in your browser against the public chain; nobody has to be taken at their word.
- A receipt
Shows that one transaction created a payment of a stated amount that only the holder of a stated shielded address can spend. Compare that address with the one you expect. It does not show who paid: the payer and the recipient can both make the same receipt, and nobody else can.
- A source-of-funds report
Shows where the money behind one withdrawal entered the pool. It opens the wallet’s own transactions on that path, back to the deposits, and each step is checked against the chain. Where the path reaches money that came from another wallet, it stops, and this page says so.
It does not divide the withdrawn amount among the deposits. Payments are merged and split on the way.
- A viewing key
Lists every payment a wallet has received, with its amount: from others, and its own deposits and change. It cannot show which of them were spent, so it gives neither a balance nor what was paid out. Whoever gave it to you cannot take it back, so keep it as carefully as they would.
- What a check cannot tell you
Whether the person in front of you is the one the document is about. And nothing here changes what Loch is: unaudited software. Read the cautions.
