TAKE A CLOSER LOOK

A card, two views and an accessible record.

This page tests importing an existing NFT into the gallery. Its original name is Carte One Piece fictive — Héroïne des mers (démo). The metadata describes a demonstration, without certification or rights transferred to an artwork or physical object.

What the images show

The front depicts a pink-haired character among sunflowers, with SAMPLE across the image. The back shows a golden compass against a dark blue background. These observations concern files, not a physically inspected card.

A history still to document

The metadata declares 2025, Japanese origin and a like-new condition. These remain unverified declarations. No manufacturer, dimensions or acquisition history has been invented. The source explicitly calls the provenance and history fictional.

NFT 7 is on Polygon Amoy, a test network separate from production. Its contract points to the original metadata. Media are stored on Arweave, rather than directly in the Polygon contract.

Limits of this trial

Reading the token and comparing file hashes does not certify an official card, PSA grading or a physical NFC link. No price, sale offer or illustration usage rights are assigned by this page.

A few useful details.

Does the NFT exist?

Yes. Token 7 was read on Polygon Amoy, a test network. This does not establish physical card authenticity.

Is the card certified PSA 10?

No. The metadata explicitly states that this claim is simulated.

Why are there only two images?

The metadata references three files, but front and preview contain identical bytes. The back is the second distinct view.

Has the NFC chip been checked?

No. The NFC identifier is fictional and no physical chip has been programmed or verified according to the metadata.
