Retrieve any NFT from your EVM blockchain collection instantly and securely with a discord bot using QuickNode

Overview

When we're in the world of blockchain, we often hear about the great things one blockchain can do. So, we decide to create something on that blockchain.

For example the: Base, Polygon ZKEVM, Filecoin Virtual Machine , and more...

We discovered something common called the Ethereum Virtual Machine.

In simple terms, it's like a place where we can deploy our smart contracts. However, sometimes, some smart contract actions don't work together because each blockchain has its own rules.

However, we realize that there aren't many tools available to help us, and the tools provided by new companies often don't work well.

I've taken steps to assist you. If you're curious or new to this, you can use this tutorial to understand and build on this solution.
You can build this:

Let's goooo on this journey! 🚢

Disclaimer: This tutorial only works if your smart contract has the standard methods for ERC721.

 function balanceOf(address) external view returns (uint256)
 function totalSupply() external view returns (uint256)
 function tokenOfOwnerByIndex(address,uint256) external view returns (uint256)
 function tokenURI(uint256) external view returns (string)
