Users can create auctions for items with any cryptocurrency of their choice. They must submit a contract on the platform in order to get their auction started. The application programming interface can show users market data with statistics and insights in the form of graphs so that users can see how their digital assets are trending. Users can sell their assets in packs, airdrop rewards to customers if so desired, and create lootboxes.

There are more than three million digital assets on the platform and cryptocurrencies such as Ethereum are used for the exchanges. Sales are conducted through smart contracts on the platform and users can keep their commission after paying a fee to OpenSea.
