How to code a crypto collectible erc721 nft tutorial (ethereum)
The commercialization of Web 3. Non-fungible tokens NFTs are an increasingly popular way of providing proof of ownership and authenticity of digital assets. Many large enterprises, in particular those with large intellectual property holdings, are seeking to build new customer experiences and product offerings with digital items, collectibles, content, and moments in the form of NFTs. The concept of fungibility refers to the ability for an asset to be exchanged equivalently with another asset of like kind. A practical example of a fungible asset is the US dollar, where you can trade one dollar for another knowing the value is exactly the same regardless of which dollar you have.

How to Create Your Own NFTs on Ethereum Using Mintable
June 11, 14 min read An NFT non-fungible token is a fascinating new technology that represents ownership of an asset digitally.
Fungibility is essentially the ability to exchange an item for a similar item of the same value. Consider a five-dollar bill. It always equals the same amount anywhere in the world. You can exchange five one-dollar bills for a single five-dollar bill, and they are worth the same value all the time.
On the other hand, non-fungible items do not have the same value in comparison to each other. For example, an exact replica of the Mona Lisa is not equal in value to the original painting, despite being the same in every way.
Non-fungible items are inherently unique and cannot be considered equivalent to any other item. An item can be both fungible and non-fungible. For example, while two seats in economy class on a plane are worth the same price, one person may place sentimental value on a window seat, decreasing the value of every other seat for that person.
A blockchain is a public database or digital ledger that keeps track of transactions. It is replicated across several computer systems that are part of the chain. Minting is the process of creating something for the first time, or in our case, publishing a unique instance of our ERC token on the blockchain. No two tokens are ever the same, so each time you mint a new token with the same block of code, a new address will be generated.
We can use a smart contract to create and track our tokens. NFTs contain information or data about the asset they represent, which could be a digital item like a Tweet or a physical item like a hoodie. Each time we mint a new NFT, we use the smart contract code that has been deployed to the blockchain. Ethereum uses multiple networks. The network used in production is usually referred to as Mainnet and the others, which are used for testing, are called Testnet. Note that when we eventually deploy our NFT, either to production or to the Mainnet, the transaction history and balances we have on the Ropsten Testnet will not carry over.
A network is considered private if its nodes are not connected to the public blockchain. You can run the Ethereum blockchain on a private network, like your local machine, or on a group of machines, like consortium networks, that are not accessible on the Mainnet or Testnet. Running the Ethereum blockchain on a group of machines like an intranet would require validating transactions with a node , an Ethereum software running on a client that verifies blocks and transaction data.
HardHat and Ganache are two examples of Ethereum blockchain development environments that you can run on your local machine to compile, test, deploy, and debug your smart contract application. Faucets, like the Ropsten Faucet , are web apps that allow you to specify and send test ETH to an address, which you can then use to complete transactions on a Testnet.
The price of ETH on exchanges is determined by transactions occurring on the Mainnet at any given time. As previously mentioned, nodes verify blocks and transaction data. You can create your own node using clients like Geth and OpenEthereum and contribute to the Ethereum blockchain by validating transactions and blocks on the blockchain.
You can skip the process of creating your own node and instead use one hosted on the cloud with a node-as-a-service platform like Alchemy. We can quickly move from development to production and ensure that we get important metrics for our application.
Alchemy has been described as the AWS for blockchains and provides developer tools that allow us to view insights into how our application is performing.
I enjoy photography and take a lot of pictures on my mobile device. What better way to protect my work than to mint an NFT that I can transfer to anyone who loves my photos? They can then use the NFT data on either the Ropsten Testnet or the Mainnet to prove that they own the rights to the original image. On the next screen, select the free plan. On the following screen, you can avoid entering payment information by hitting the Skip for now button, but you may choose to do that at a later time.
On the last screen, select the Capped Capacity option. We need to create a wallet to hold an Ethereum account. MetaMask will automatically generate a wallet address denominated in ETH. Simply click on Account 1 to copy your wallet address. First, enter your wallet address, which you can copy from above, and the site will send 1ETH to your wallet. First, create a new directory for our project and initialize npm:.
We need to set up Hardhat , a development environment for Ethereum that allows us to compile our application on our local machine and test functionality before deploying to the Ropsten Testnet. Select Create an empty hardhat. Smart contracts are simply applications that can be run on the Ethereum blockchain. They are written in a language called Solidity. In your Chrome browser, open up the MetaMask extension, click the three dots in the top right, and select the Account Details option.
Next, click the Export Private Key button. Enter your password to see your private key, then copy it. To keep our keys secure, we will install the dotenv package:.
Create a. Head to the hardhat. You can read more about configuration files in Hardhat. You should see a success message like the one below. You can ignore the warnings that appear in the terminal. Now, we can run the Hardhat deploy task :.
We add the --network ropsten flag to tell Hardhat to connect to a specific network, in our case, Ropsten. From our terminal logs, we can see the newly created address for our smart contract. Head to the Ropsten Etherscan and paste your contract address into the search bar. You should see details about your contract within one minute. Our smart contract code takes in two arguments: the receiver address and a tokenURI.
The tokenURI links to data that we would like to attach our token to. Data stored on the blockchain needs to be processed, verified, and replicated across multiple networks, making storing data on the blockchain very expensive.
Uploading an entire image to the blockchain is not advisable, and you can store only the metadata for the NFT instead. Additionally, anyone who has access to the content at a URL may change it. The link to those images was still present on the blockchain, however, the original content had been completely altered.
IPFS is a distributed system for storing and accessing files that uses content addressing to tackle the problem above. Once a CID is generated for a piece of data, that CID will always represent that data, and the data cannot be changed. The URI will be resolved by your user agent browser to display the content. According to its docs, web3.
Alchemy wraps around the Web3. In your scripts folder, create a file called mint-nft. Then, add the following block of code:. In the root of your application, create a file called nft-metadata. Remember to change the image value to use the CID that was generated when you uploaded your image to Pinata:. Save the file, then head back to Pinata to upload the file. To mint the NFT, grab the contract address that was created when our smart contract was deployed to the Ropsten Testnet.
You can see this in our terminal logs. Add the address to our. Add the following code into our mint-nft. Add the following block of code to the mint-nft. If you open the link above in our browser, you should see our nft-metadata. Wait a few seconds, and you should get a response like the image below in our terminal. Scroll down to input data, then click the decode input data button.
Hopefully, you see why NFTs are causing such commotion. This is a fascinating technology that is likely to stick around a while. In production, the steps are exactly the same as in this tutorial. You can see all the code for this project on my GitHub. LogRocket is a frontend application monitoring solution that lets you replay JavaScript errors as if they happened in your own browser so you can react to bugs more effectively.
Instead of guessing why problems happen, you can aggregate and report on what state your application was in when an issue occurred. Build confidently — Start monitoring for free. Great Tutorial! Just what I needed. However, something to note: when using npm — 1. Should update it to make it easier for newer programmers. Help me please! Thanks for the great tutorial uncle. I had issues with creating the contract — found the solution using Stack Overflow — it required importing a particular library.

ERC is a free, open standard that describes how to build non-fungible or unique tokens on the Ethereum blockchain. While most tokens are fungible every token is the same as every other token , ERC tokens are all unique. Think of them like rare, one-of-a-kind collectables. ERC defines a minimum interface a smart contract must implement to allow unique tokens to be managed, owned, and traded. It does not mandate a standard for token metadata or restrict adding supplemental functions.
