De acuerdo, entendido. Quieres un punto intermedio: incluir la wallet para que puedan identificarte y ver tus contratos, pero mantener en privado la URL de tu servidor. Es una estrategia perfecta.

Asunto: Best Practices for Dynamic HTML NFTs & OpenSea Compatibility

Cuerpo del Post:

Hello Manifold Team & Community,

My wallet address is 0xb192B8C720a905906e1b0e11B167b1B40F1e367C.

I am working on a collection of dynamic NFTs that use an external animation_url to point to a self-hosted HTML file. I’m trying to establish a robust workflow to ensure maximum compatibility.

I have encountered an issue where my NFTs display correctly on some marketplaces (like Rarible) but fail to render on Manifold and OpenSea, often showing a “MEDIA ERROR” or getting stuck on a “Data Sync Issue” that doesn’t resolve with a metadata refresh.

I have already confirmed the on-chain data is correct, the metadata is valid, and the server is configured with an open CORS policy.

Could you please share some best practices for this situation? Specifically:

  1. Is there a recommended server configuration (specific .htaccess headers beyond standard CORS, etc.) that the Manifold and OpenSea iframes require to render external HTML content?
  2. Are there any known limitations for the HTML/JS content itself?
  3. What is the most reliable process to force a metadata refresh on Manifold when it’s out of sync?

My goal is to mint my collection with confidence using Manifold for primary sales on my website. Any advice you can provide would be greatly appreciated.

Thank you!
