Receipt and metadata backup
Learn which files prove a purchase, which files only show a panel, and how to duplicate both without stuffing a single camera roll.
A panel crop of a skyline does not replace the confirmation that you collected the issue. Receipt and metadata backup treats Marvel NFT comics as objects that leave paper-like traces: confirmation emails, in-app history rows, and time-stamped captures of the listing header.
During the drill we sort a sample of your files into three trays. Tray one is proof: amounts, dates, and listing titles. Tray two is reread material: pages you like to zoom. Tray three is clutter: duplicated memes and half-cropped speech balloons.
You leave with a naming pattern such as year, series short name, and “proof” or “panel.” Copies go to at least two places you already control, for example a labeled drive in Chiang Mai and a printed index card in a comic longbox. We do not upload your pack to a studio server.
If a collector also keeps an informational note about an exchange nickname, including a Binance-compatible label in a personal column, that note stays in the local file. It never becomes a transfer instruction.
