How to Get Verified NFT Collections

Today’s tutorial will show you how to get all verified NFT collections of an address using the Moralis NFT API. Thanks to the accessibility of this API, you can get this data with a single API call to the getWalletNFTCollections() endpoint. Here’s an example of what it might look like:

const Moralis = require("moralis").default; const { EvmChain } = require("@moralisweb3/common-evm-utils");  const runApp = async () => {   await Moralis.start({     apiKey: "YOUR_API_KEY",     // ...and any other configuration   });    const address = "0x1f9090aaE28b8a3dCeaDf281B0F12828e676c326";    const chain = EvmChain.ETHEREUM;    const response = await Moralis.EvmApi.nft.getWalletNFTCollections({     address,     chain,   });    console.log(response.toJSON()); };  runApp();

All you have to do is add your Moralis API key, configure the address and chain parameters to fit your query, and run the code. In return, you’ll get a response containing an array of NFT collections. 

Each collection will have a verified_collection property that is either true or false. If it’s true, it means that the NFT collection is verified. Here’s an example of what the response might look like: 

//… {   "status": "SYNCING",   "page": "2",   "page_size": "100",   "result": {     "token_address": "0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB",     "contract_type": "ERC721",     "name": "CryptoKitties",     "symbol": "RARI",     "possible_spam": "false",     "verified_collection": "false"   } } //…

Overview 

The non-fungible token (NFT) space has been growing rapidly over the past few years, and the market is filled with millions and millions of NFT collections. Some are established projects like Pudgy Penguins and CryptoPunks, while others are irrelevant collections and NFT spam. Due to the vast number of projects, you’ll need an easy way to filter out the noise when building NFT projects. Fortunately, this is where the Moralis NFT API enters the equation, allowing you to seamlessly get verified NFT collections with a single line of code. To learn more about how this works, join us in this article as we show you how to get all verified NFT collections of an address in a heartbeat! 

We’ll kickstart today’s article by first explaining what verified NFT collections are. In doing so, we’re also going to explain why you need this NFT data when building Web3 projects. From there, we’ll jump straight into the tutorial and show you how to get verified NFT collections in three straightforward steps using Moralis. Lastly, to top things off, we’ll dive into some prominent use cases for verified NFT collections.

What are Verified NFT Collections? 

Whenever you query all NFT collections of an address using the Moralis NFT API, you receive an array of collections. Each collection in the array will have a verified_collection property that will either be true or false. If it’s true, it means that it’s a verified NFT collection. 

But what exactly does it mean that a collection is verified? 

In short, verified NFT collections are projects that have been vetted by an NFT marketplace. Whenever you see a checkmark next to an NFT collection on websites like OpenSea, Rarible, or Blur, it usually means that the marketplace has verified it.

There are many benefits to having verified NFT collections, and some prominent examples can be found below: 

1. Visibility: Verified NFT collections can gain more visibility on their respective marketplaces, making it easier for users to find them. 

2. Trust: Verifying NFT collections brings greater trust to the Web3 ecosystem, allowing users to effortlessly distinguish between legitimate projects and potential scams.

3. Scam Detection: By distinguishing between verified and unverified projects, it becomes significantly easier for users to identify potentially fraudulent collections. 

All in all, verified NFT collections bring greater trust to the NFT ecosystem by helping community members identify authentic creators and projects. It also helps creators with reach as it makes it easier for users to trust their particular collection. 

Why You Need Verified NFT Collections 

The NFT market has been growing fast over the past few years, and we have seen millions and millions of collections emerge during this time. This includes legit and verified projects like CryptoPunks, Pudgy Penguins, etc. However, it also includes many unverified projects that are either irrelevant or likely to be scams. 

Due to the vast number of projects, you generally need a way to filter out the noise when building an NFT project. In doing so, you’ll be able to present collections that are relevant to your users, providing a more seamless user experience.

3-Step Tutorial: How to Get Verified NFT Collections 

In the following sections, we’ll show you how to get all verified NFT collections of an address using Moralis. And thanks to the accessibility of the Moralis NFT API, you can now seamlessly get the data you need in three straightforward steps: 

1. Set Up Moralis
2. Create a Script
3. Run the Code

However, before jumping into the tutorial, you must complete a few prerequisites!  

Prerequisites 

In this tutorial, we’ll show you how to get verified NFT collections using JavaScript. As such, before you can continue, you must have the following ready:

With these ready, you’re ready to jump straight into the initial step of the tutorial!  

Step 1: Set Up Moralis 

In order to call the various endpoints of the NFT API, you initially need a Moralis API key. So, if you haven’t already, click on the ”Start for Free” button at the top right and set up your Moralis account: 

With an account at hand, you can head on over to the ”Settings” tab, scroll down to the ”Secrets” section, and copy your API key:

Keep your API key for now, as you’ll need it in the second step of this tutorial to get all verified NFT collections of an address. 

Next, you additionally need to install the Moralis SDK. As such, set up a new project in your integrated development environment (IDE), open a new terminal, and run the following command in the root folder: 

npm install moralis @moralisweb3/common-evm-utils

That’s it for the first step; you’re now ready to start coding and creating the script for getting verified NFT collections! 

Step 2: Create a Script 

To get verified NFT collections owned by an address, you simply need a single API call to the getWalletNFTCollections() endpoint. As such, start by creating a new ”index.js” file in your project’s root folder and add the following code:

const Moralis = require("moralis").default; const { EvmChain } = require("@moralisweb3/common-evm-utils");  const runApp = async () => {   await Moralis.start({     apiKey: "YOUR_API_KEY",     // ...and any other configuration   });    const address = "0x1f9090aaE28b8a3dCeaDf281B0F12828e676c326";    const chain = EvmChain.ETHEREUM;    const response = await Moralis.EvmApi.nft.getWalletNFTCollections({     address,     chain,   });    console.log(response.toJSON()); };  runApp();

From here, you now have to make a few configurations to the code. First of all, add the Moralis API key you copied earlier by replacing YOUR_API_KEY:

Next, configure the address and chain parameters to fit your query: 

We then pass the parameters above when calling the getWalletNFTCollections() endpoint: 

That’s it for the script; you only need a few lines of code to get verified NFT collections when working with Moralis. From here, all that’s left is running the script! 

Step 3: Run the Code 

For the final step, open a new terminal, cd into your project’s root folder, and run the following command: 

node index.js

In return for running the code, you’ll get a response containing an array of all NFT collections owned by the address. Each collection in the array has a verified_collection property that is either set to true or false: 

//… {   "status": "SYNCING",   "page": "2",   "page_size": "100",   "result": {     "token_address": "0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB",     "contract_type": "ERC721",     "name": "CryptoKitties",     "symbol": "RARI",     "possible_spam": "false",     "verified_collection": "false"   } } //…

If the verified_collection property is true, it means that the collection is verified on OpenSea:

From here, you can seamlessly sort through the array to get all verified NFT collections in a heartbeat! 

Congratulations! That’s it; you now know how to get all the verified NFT collections of an address using Moralis!
