Purpose

This article explains how to view items (NFTs) held in a contract on the Ethereum network using Etherscan. It shows the process of viewing items (NFTs) in a contract, enabling you to see the blockchain data that confirms the number of items in a wallet.

Assumptions Made

This article assumes you understand the information in the following articles:

What are Non-Fungible-Tokens (NFTs)?

What is a Blockchain?

Procedure

1) Visit OpenSea.io

2) Search OpenSea for the desired item. We’ll use a Wheel Assembly in this example.

3) Click on the item.

4) Copy the item ID in the URL; it’s the text after “assets/” and before the next /
The example in the image below would have the item ID of “0xc36cF0cFcb5d905B8B513860dB0CFE63F6Cf9F5c”

5) Visit etherscan.io and enter the item ID in the search bar; we will use the item ID from step 4 as an example. Hit enter or click the magnifying glass.

6) Click on Contract

7) Click on Read Contract

8) Click on balanceOf

9) Enter your wallet address into the _owner (address) field

       9a) Enter the item ID (from step 4) into the _id (uint256) field
       9b) Click Query

10) You should see a quantity of that item listed after unity256. This is the amount of this NFT in the entered wallet. In this example, this wallet has 20 Wheel Assemblies.
