# Heroine of the seas Heroine of the seas demonstration card: two original views, Arweave metadata and NFT 7 on Polygon Amoy. No certified physical object. - Canonical page: https://cartes.aroa.blue/en/objects/heroine-des-mers/ - Language: en - Object reference: MAT-004 - Category: Collectible card - Fictional demonstration object: true > Fictional demonstration object; generated image and illustrative specifications. ## Description and history 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. ## An accessible digital link 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. ## Declared characteristics - **Nature**: Demonstration card — declared fictional object - **Declared collection**: Prototype Héroïne des mers - **Declared year**: 2025 — unverified - **Declared materials**: Illustrated cardboard in a protective case — to be confirmed - **Declared condition**: Like new — not checked on a physical piece - **Declared origin**: Japan — unverified ## Provenance This record comes from NFT 7's public metadata.

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. ## Documents - [Descriptive dossier](https://cartes.aroa.blue/en/objects/heroine-des-mers/dossier.json) - [JSON-LD](https://cartes.aroa.blue/en/objects/heroine-des-mers/index.jsonld) - [Object index](https://cartes.aroa.blue/en/index.json) - [Français](https://cartes.aroa.blue/objets/heroine-des-mers/index.md)
