A PnL card is a shareable summary of a trade or a result. The problem with the usual trading screenshot is that anyone can edit it, so nobody can really trust it. Hyperprop fixes that: every PnL card is verifiable by anyone who sees it. Download a card, check if it is real, and settle it in seconds. The proof does not come from your word or your editing software. It comes from the platform the trade was made on.
The verification page
Each card carries a QR code linking to a verification page (at a /v/ link). It is a clean page: the Hyperprop logo, the card, share actions, and a detail table. The trade direction is color-coded (green for long, red for short), the net P&L is colored by sign, and there is an explainer on the verified checkmark.
The same everywhere
A card looks identical wherever it appears: the share dialog, your profile, the verification page. The downloaded image matches what you saw on screen exactly, including trades made of several fills, which are added up into the correct total.
Managing your cards
On your profile, clicking a saved card opens a single Manage card dialog: a visibility setting, a notes editor, a link to the share page, and remove. Edits save behind a Save button, not on every keystroke. Remember, a card is only as public as you set it, and non-public ones are clearly marked Private or Unlisted.
