That’s all there is to create a collection on OpenSea.

OpenSea Royalties

On OpenSea, NFTs can be programmed to a point where each transaction will include royalties, allowing creators to be rewarded fairly for their work. NFTs are fully created and stored on the blockchain. This allows them to be seamlessly traded from a wallet to a wallet, with royalties that pay out every time they move. In fact, on OpenSea, you can set up royalties to 10%. To do this, you need to go to your collection editor and adjust the percentage fee field. Here you can set up a fee of up to 10%. Here, you can also specify the payout address where you wish to receive the fees. These royalties also apply to primary sales. If you set up a sale price of 1 ETH and have your royalty at 5%, you will receive 0.925 ETH from the sale, as 2.5% goes to OpenSea, and 5% is the royalty. In two to four weeks, you will receive back the 5% royalty or 0.05 ETH.

How to make an NFT Collection

From OpenSea, go to your profile icon and go to the “My Collections” tab. Here, you can select “Create a Collection” to start your new collection. Once you have multiple collections, they will be viewable within this tab. That being said, you need to enter your collection’s name, description and eventually upload an image or a logo. Keep in mind that you aren’t making NFTs, and all of these details can be updated in the future. Once your collection is created, you can begin adding items. To do this, click on “Add Items” to start. If you want to update your banner image, you need to select the pencil icon on the top right, and your banner image will look different across multiple devices, so the recommended dimension is 1400 x 400. The text should be avoided for the best results. Additionally, once you have uploaded your NFT files, you can also add a category to the collection, as this will increase its level of discoverability on OpenSea. You can even add social media links related to your projects. After you fill out all of the fields, you can decide on the secondary fees or royalties percentage.

Refreshing Your Metadata if It Is Not Active

You should consider refreshing your metadata as well, assuming it is not active. The process of doing so is fairly straightforward as well. All you really need to do is visit the item page and click on the metadata refresh button. This should be located right under the blue “Sell” icon.

OpenSea Metadata Freezing Issues

Freezing is an important aspect of NFTs due to the fact that it locks the info so it cannot be altered later. This will permanently lock and store your NFT on decentralized file storage, which allows your data to be accessible for other clients to view and use. Your item will be forever stored and will never be lost or missing. However, there are issues associated with this. For example, most NFTs have a function within their smart contract that returns the metadata which corresponds to the token identified the token has. The return value is typically a URI on the cloud server, which the developer runs. If the content, in this case, is controlled by such a server for the NFT, then the NFT is centralized and can suffer from impermanence and fallibility issues.
