If you are just starting your project and are ERC-721 compliant, the process is fairly quick and easy. Just go to our developer tutorial and follow the instructions.
I've already built my project but it doesn't comply with the metadata standard. Can I still get listed?
Yes! Depending on the structure of your smart contract, we may be able to do a custom integration. In particular, if your contract is ERC721, you can provide us with a metadata URL for your items that should be relatively easy to integrate.
Just send us a note at [email protected] and we'll reach out to you with next steps.
That's great that you have a fresh start. We highly recommend following our OpenSea Developer Tutorial to learn how to properly structure your contract and metadata for full OpenSea compatibility. It's pretty quick to get started, and it's actually a lot of fun!
When you add the new contract with the same name as your previous contract, it will automatically have a new storefront with "V2" after the name (or "V3", "V4", etc.). For example, if we deployed another CryptoPuffs contract, it would have the name "CryptoPuffs V2" and be available at https://opensea.io/category/cryptopuffsv2
To update your smart contract, simply rename the old contract to CryptoPuffsOld, and rename the new contract to CryptoPuffs through the storefront customizer.
After you've updated your contract, you'll probably want to get rid of the old one. We don't have an interface for deleting old smart contracts, so you'll need to contact us on Discord. We'll be sure to get on it as soon as possible!
OpenSea provides a powerful marketplace for your Dapp, allowing your items to be bought and sold quickly and easily. OpenSea allows you to focus on design, content and your users, while still having a full-featured marketplace for your project's digital assets.
Your OpenSea storefront can be tailored exactly to your project, creating a fully customizable landing page and marketplace. If you're looking for even more customization that the native OpenSea marketplace, you can explore our white-label solution, as well as our OpenSea SDK for creating auctions directly inside your application.
Thousands of users already use OpenSea to discover, purchase, and sell rare digital items. By listing your game on OpenSea, you'll open up your items to a large user base of gamers, traders, and crypto enthusiasts. This increases both the liquidity of your items and the discoverability of your app.
In addition to peer-to-peer trading, OpenSea can be used as a tool for the initial sale of your gaming items. Check out our section on running an initial item sale to learn how this is possible.
Our self-serve storefront creation only works with ERC-721. However, we are occasionally able to do custom integrations with non-ERC721 items. If you aren't using that standard, integration might take a bit longer.
Yes! We let you decide whatever fee you want to charge on your items — meaning that every time an item is sold, you (the developer of the project) will receive a percentage cut of the sale.
Fees can either be levied on the seller or the buyer. To understand the difference, consider a user selling an item for 1 ETH. With a 2% seller fee, the buyer would pay 1 ETH for the item and .02 ETH would go to the developer (you), meaning the seller would receive .98 ETH. With a 2% buyer fee, the buyer would pay 1.02 ETH for the item, .02 ETH would go to the developer (you), and 1 ETH would go to you.
You're free to play around with whatever fees you'd like in the storefront editor.
OpenSea provides it's marketplace infrastructure for free—it's entirely free to get started setting up a marketplace and using our platform. As compensation for this service, 2.5% of each sale will go to OpenSea.
Yes! The simplest way to do this is to simply set up an Ethereum account and auction off your items using the standard OpenSea auction flow. See running an initial item sale for more details.
If you have a more complex way of auctioning off your initial items (perhaps some method of randomly generating the items), check out advanced presale structure. If that's still not suitable for your needs, feel free to reach out to us at [email protected] to see if we might be able to help you out.
