How to make a smart contract for nft

The deluge of static NFTs are boring me. What do I mean by static? Basically what is sold is what that piece will forever be. You might counter me, saying, “Isn’t that the basic premise of art appreciation… that the piece is finished and we get to consume and collect it?”

Yes, but smart contracts make it possible for NFTs and the digital art encapsulated to evolve over time. While I don’t find anything wrong with static NFT art, as we look into 2022, dynamic NFTs are what we’ll be talking about and praising as the new example to follow.

The reason I bring dynamic NFTs up is that over the past week I came across two really great examples that I think we’ll see many people biting.


Created by Pak, one of the more recognizable names in NFTs, merge.

Chainlink Price Feedshave the potential to empower DeFi protocol infrastructure that can compete with traditional financial systems in terms of trade execution and risk management quality.

In this nextcode example, we’ll deploy and interact with a Solana program that makes use of Chainlink Price Feeds on the Solana devnet cluster.


  • NodeJS v14 or greater & NPM
  • The latest stableRustbuild
  • Solana CLIv1.7.11 or later
  • Git

The Chainlink Solana Starter Kit

TheSolana Starter Kitis a pre-packaged repository that contains a smart contract that simply connects to a Chainlink Price Feed account on devnet, and retrieves and stores the latest price of thespecified price pairinto an account, which is then read by an off-chain client.

Additionally, it allows networks to store data transparent and immutable.

What’s the Advantage of Using a Smart Contract Wallet?

Part of the advantage of a smart contract wallet is much less reliance on different mediums of restoration.

However, every wallet we’ve protected to date in our wallet collection has required a few forms of statistics for restoration (and access) purposes, including a personal key or mnemonic phrase.

However, smart contract wallets use types of restoration that don’t require writing down and remembering lengthy strings of statistics.

Why do NFTs use Smart Contact Wallets?

NFTs use smart contracts and the blockchain to create unique and permanent information, allowing the ability not to divide this digital art into smaller units for sale.

Furthermore, the smart contracts are there to make sure that the digital assets are one-of-a-kind and non-replicable, which makes the NFTs scarce, rare and, as the result, valuable. All these can be represented digitally on the blockchain.

There are a series of if/then and when statements written as a code into the blockchain in the very core of a smart contract.

A network of computers executes all the agreed upon actions coded in the smart contract and each action is executed under the condition that the predetermined conditions are met and verified.

How Are Smart Contracts Created?

When you mint and NFT, you basically write the underlying smart contract code which in fact decides the qualities of the NFT and adds these qualities to the relevant blockchain the specific NFT coded in.

SuperRare does this by an application form that collects the name, email, and specific details of the artwork, while other platforms may add in disclaimers that the buyers do the research before buying any NFT.

How do smart contracts prevent counterfeiting?

When you buy an NFT a unique token is issued which has the information and the details of the smart contract. This gets registered on the blockchain. Now this information on the blockchain is public and includes the record of purchase and proof of ownership.

The owner can display the asset and sell it.
If the image is reproduced (which is definitely possible if you display the work to the public) the blockchain will prove the ownership and the reproduced images or assets would be worthless.

How to create smart contract for nft collection

There are two primary ways in which smart contracts and NFTs can interact with each other: NFT’s can be embedded in smart contracts and NFT’s can be embedded within smart contracts. A smart contract can own an NFT within it which can be later transferred to a user or another contract based on the rules and events defined in the smart contract.

On the other hand, a smart contract can be embedded in an NFT to call and access assets within the NFT.

For example, a user can access a song which is embedded in an NFT through a smart contract. They would agree upon the terms using the smart contract, pay the agreed upon amount and then get access to that song.

Once again, take note of this Program ID, as it will be required when executing the client. This can then be checked on theSolana Devnet explorer.

Interacting With the Deployed Program

To interact with the deployed program, the Chainlink Solana Demo repository contains aclientwritten in JavaScript using theAnchor frameworkand theSolana web3 API.

The Client

The client is a JavaScript script that takes two parameters, a deployed program ID, and aPrice Feed account address.
It then creates a connection to the deployed program and passes in the specified price feed account and an account to store the retrieved price data. Once the on-chain program execution has completed, it simply reads the price data from the account that was passed into the program.

They are the ultimate permanent identification information, making your NFTs non-replicable and unique.

What Are The Different Standards Of NFT Smart Contracts?

Now that you understand what an NFT smart contract is, let us move on to the two different standards of NFT Smart Contracts. They are both Ethereum standards and are widely popular for their secure transactionality.

ERC 721 Standard

The NFT Smart contract Ethereum in ERC 721 Standard is the very definition of the software.
It is found on the Ethereum blockchain and makes NFTs one-of-a-kind and everlasting on the blockchain as an investment. All in all, it is what makes NFTs non-fungible, harder to replicate, and a popular unique digital asset on the Ethereum blockchain.

A proper NFT contract example would be how concert tickets work.

So collecting gets harder and harder over time as the number of collectors and number of mass tokens will always be getting smaller.

What I like about this is that Pak boiled the concept of being a power-collector down to its most basic unit – quantity collected. Collectors don’t have to worry about rarity or any special collectible characteristics.
Just acquire more and your NFT will grow. As you acquire more, your NFT becomes more valuable because it has more mass.


The second example of a dynamic NFT that really caught my eye was OG:Crystals. The dynamic concept they explore is that the NFT changes based on the information in a given collector’s wallet.

It starts with OG:Crystal seeds. After owning one for 5 days, your seed grows into a crystalline / coral reef structure.

Also print the value to the program output let decimal_print = Decimal::new(round.answer, u32::from(decimals)); msg!(“{} price is {}”, description, decimal_print); Ok(()) }

Deploying the Program

The first step is to clone the repository.

git clone cd solana-starter-kit

Once this is done, you can install the required dependencies, including the Anchor framework.

npm install

Note for Apple M1 chipsets: You will need to perform an extra step to get the Anchor framework installed manually from source, as the NPM package only support x86_64 chipsets currently, please run the following command to install it manually:

cargo install –git –tag v0.20.1 anchor-cli –locked

Next, you need to create a newkeypairfor your account.
