This tutorial will teach you how to build an ERC721 from start to finish, with immediate OpenSea marketplace integration.
Estimated time: a few hours!
Have you already deployed your ERC721 contract on the mainnet? It's dead simple to get your items viewable and tradeable on OpenSea! This guide will show you how to configure your existing ERC721 items to get them to show up on Op.
If you haven't deployed to mainnet yet, we recommend the main OpenSea Developer Tutorial.
If you're running a crowdsale for your ERC721 items, OpenSea has a suite of tools that allows you to auction your items off to an initial set of users. Note that we recommend completing the main OpenSea Developer Tutorial first.
In addition to an instant marketplace for ERC721-based items, OpenSea provides an HTTP API for fetching non-fungible ERC721 assets based on a set of query parameters.
