Frequently asked questions (FAQ)

How do I get listed on OpenSea?

1. Fill out our developer onboarding tool.
2. An OpenSea team member will contact you right away

If you are ERC-721 compliant, the process is fairly quick and easy. If you have a different structure for your NFTs, it may take a bit more time, but is still possible.

Does OpenSea only list and support ERC-721 assets?

Nope, OpenSea supports ERC-721 and other types of digital assets. ERC-721 is easier and quicker to implement, so if you aren't using that standard, it might take a bit longer.

We haven't launched yet, can you help us?

Yes! Please fill out our developer onboarding tool. We'd love to help you launch your project and sell digital assets.

Can you help us create digital assets?

Yes! Please fill out our developer onboarding tool.

How should I structure my MetaData?

For OpenSea to immediately integrate your asset, you can do the following.

Your tokenMetadata function in your ERC721 asset should return a URL, such as https://api.cryptofluffs.io/items/1. This URL can return a JSON blob of data with the metadata for your token. The data should be structured as follows:

{
    "imageUrl": "https://api.cryptofluffs.io/abcdef.png",
    "externalUrl": "https://cryptofluffs.com/fluff/3",
    "description": "Hi there! I'm Herbert.",
    "name": "Herbert",
    "properties": {
        "color": "green",
        "stamina": 45,
        "health": 32.1
    }
}
