Solana has turn out to be one of many main programmable blockchains due to its pace and low transaction charges. Consequently, many initiatives specializing in NFTs have determined to make the most of Solana, and at this level, there are quite a few Solana NFTs (non-fungible tokens) value exploring. That mentioned, in case you are an NFT developer, realizing the way to current varied NFTs in a dapp on the Solana blockchain is essential. On this article, we are going to current a dapp that may do exactly that – showcasing NFTs on Solana. What’s extra, within the upcoming sections, we are going to illustrate the way to construct a Solana NFT explorer shortly and simply with the assistance of Moralis. Due to Moralis’ Solana API, you possibly can simply fetch NFT metadata after which use the picture URL to show NFTs neatly. Moreover, you can even construct a Solana NFT explorer with extra filters, due to Moralis.
With that in thoughts, now’s a good time to be taught extra about programming on the Solana chain.

Though we’re constructing a Solana NFT explorer herein, we may’ve centered on another main community. In spite of everything, Moralis can also be cross-chain interoperable. So, create your free Moralis account and comply with our lead.
Construct a Solana NFT Explorer Like Ours – Demo
Earlier than we present you the way to construct a Solana NFT explorer, let’s check out our instance dapp. As such, you will notice what to anticipate from immediately’s tutorial. You’ll additionally have the ability to resolve if you wish to roll up your sleeves and construct your individual occasion of our Solana NFT explorer.
The next screenshots symbolize the gist of our Solana NFT explorer dapp. Initially, our instance dapp is empty:
Furthermore, wanting on the picture above, you possibly can see the title of our dapp, the Moralis emblem, the entry subject, and the “Search” button. Moreover, you can even see that it already populated the entry subject with an instance NFT assortment deal with. Furthermore, we simply must click on on the “Search” button to get the outcomes:
The outcomes are neatly displayed in two rows. Additionally, for every NFT, you have got the picture on the prime, its title, and we are able to see its image on the backside. Furthermore, you possibly can see that with the outcomes displayed, two extra choices seem. On the prime of our dapp, on the right-hand aspect of the “Solana NFT Explorer” title, we now have a web page navigator and a filter entry subject. With the previous, we get to maneuver to the subsequent or earlier web page utilizing the arrows. Or, we are able to additionally enter the web page quantity which we need to go to:
So far as the filter goes, we have to click on on the entry subject, after which we are able to search NFTs by symbols:
So, now you recognize what to anticipate transferring ahead. Suppose you need to discover ways to construct a Solana NFT explorer offered above, then transfer on to the subsequent part. There, you’ll first discover ways to get hold of your Moralis Web3 API key.
The best way to Construct a Solana NFT Explorer with NextJS and Moralis
Because the title suggests, the principle instruments used to construct the above-presented dapp are Moralis and NextJS. We additionally used the last word Ethereum boilerplate as a place to begin, which made issues a lot less complicated. Nonetheless, it can save you much more time by merely cloning our completed code, which awaits you on GitHub:
So, after cloning our code, you’ll be wanting on the following structure:
We’ll stroll you thru the code momentarily, however as you possibly can see within the picture above, you first must get hold of your Moralis Web3 API key.
Acquiring Your Moralis Web3 API Key
For those who haven’t finished so but, create your free Moralis account by clicking right here. Alternatively, you possibly can go to the official Moralis web site and click on on the “Begin for Free” or “Strive for FREE” buttons:
Any of those choices will take you to the signup web page:
As you possibly can see within the above screenshot, on the signup web page, it’s good to enter your electronic mail deal with and create your password. You too can use your Google account to hurry up the signup course of. In case you go together with your electronic mail and password, don’t overlook to verify your account. To do that, you’ll must click on on the affirmation hyperlink that may arrive in your electronic mail inbox.
When you efficiently arrange your Moralis account, which shouldn’t take greater than a minute, you possibly can entry your Moralis dashboard. That is the place you’ll see the “Web3 APIs” tab within the aspect menu:
On the “Web3 APIs” web page, you’ll have the ability to use the “copy” icon to repeat your Moralis Web3 API key:
Moreover, you possibly can entry all of your Moralis keys, together with the Web3 API key, inside your account settings. To get there, it’s good to click on on the “Account” possibility within the aspect menu. As soon as on the “Account Settings” web page, choose the “Keys” tab after which copy your Web3 API key:
Lastly, you possibly can return to your “.env copy.instance” file and change “xxx” together with your key. Then, rename that file to “.env.native”. That wraps up the preliminary setup!
Construct a Solana NFT Explorer with the Final Solana API
Due to the enterprise-grade Web3 APIs and SDK supplier, Moralis, we are going to simply implement the blockchain-related backend performance. In reality, we are going to solely want two explicit endpoints to create the above-presented dapp. So, to construct a Solana NFT explorer, “account/{community}/{deal with}/nft” and “nft/{community}/{deal with}/metadata” will do the trick. So, let’s do a fast overview of those two endpoints. Nonetheless, you possibly can discover them in additional element utilizing the Moralis documentation.
First, we use “account/{community}/{deal with}/nft” to get NFTs owned by the given community and deal with. This API takes within the “community” and “deal with” parameters:
For the “community” parameter, we get to decide on between the “mainnet” and “devnet” choices. With each parameters in place, we are able to strive the code and get the response. That is the place we see the “mint” values. These values are nothing however the NFT token addresses. As such, we get to make use of these values in “nft/{community}/{deal with}/metadata“:
If we now paste the above-copied “mint” deal with within the “deal with” entry subject of “path params” and once more go together with the mainnet, the code returns all of the NFT’s metadata:
Furthermore, that is all of the backend we have to construct a Solana NFT explorer.
Construct a Solana NFT Explorer – Code Walkthrough
To see how we used the above-presented APIs, entry the “getNFTs.js” and “getNFTMetadata.js” recordsdata. Each of those JavaScript (JS) recordsdata are positioned contained in the “api/SolAPI” folder:
So, if we first take a look at the “getNFTs.js” file, it accommodates the next traces of code:
import Moralis from 'moralis';
export default async operate handler(req, res) {
const { deal with, community } = req.physique;
await Moralis.begin({ apiKey: course of.env.MORALIS_API_KEY });
strive {
const information = await Moralis.SolApi.account.getNFTs({
community,
deal with,
});
res.standing(200).json(information);
} catch (error) {
res.standing(400).json(error);
}
}
On the prime, we first import Moralis, which is without doubt one of the keys that allow you to construct a Solana NFT explorer dapp. Subsequent, we use the “handler” async operate, which accommodates all we have to get hold of NFT addresses. As you possibly can see, we additionally provoke the Moralis SDK utilizing the “MORALIS_API_KEY” variable from the “.env.native” file. Nonetheless, all of the heavy lifting is carried out by the “getNFTs” Solana API endpoint from the “account” kind of endpoints.
Alternatively, the “getNFTMetadata.js” file makes use of comparable traces of code:
import Moralis from 'moralis';
export default async operate handler(req, res) {
const { deal with, community } = req.physique;
await Moralis.begin({ apiKey: course of.env.MORALIS_API_KEY });
strive {
const information = await Moralis.SolApi.nft.getNFTMetadata({
community,
deal with,
});
res.standing(200).json(information);
} catch (error) {
res.standing(400).json(error);
}
}
Basically, the one distinction is that we make the most of the “getNFTMetadata” endpoint. Furthermore, the latter is part of the “NFT” kind of endpoints.
Frontend Parts
You in all probability have some expertise with frontend improvement; nonetheless, let’s nonetheless take a better take a look at the code behind our dapp’s UI elements. Let’s begin with the “NFTCard.jsx” script:
The “NFTCard” part takes in “nftAddress” and “filterQuery“. The previous is the “mint” deal with, and the latter is what customers enter into the filter’s entry subject. Furthermore, “nftAddress” is used to get the NFT’s metadata. Additionally, that is the place we use “getNFTMetadata“.
Moreover, it’s value declaring that through the use of “axios.get“, we get to extract photographs’ URLs from the metadata URI. Right here’s an instance metadata URI and its picture URL inside:
Subsequent, we use “setNftData” to set all of the fetched NFT information into the “nftData” state variable. The latter contains the contract kind, title, image, and metadata. Furthermore, it’s the “src={resolveIPFS(nftData?.metadata?.picture)” line of code that renders the NFT picture. It makes use of the identical precept for different NFT information (see video under at 7:49).
One other necessary a part of the “NFTCard” part is the “apiPost” operate (8:01). By utilizing this operate, we simply want to present it the endpoint and the parameters that curiosity us to name the particular API.
Alternatively, the logic for our instance dapp is contained contained in the “index.jsx” file. Thus, let’s take a better take a look at that script.
UI Logic – “index.jsx”
So, “index.jsx” takes care of the UI logic. Additional, this file ensures that every one elements are displayed as offered within the demo above, together with the Moralis emblem, the “Solana NFT Explorer” title, and the deal with search bar. Clearly, the latter is the important thing that gives our dapp with the required information to course of. Furthermore, our instance dapp takes in an deal with after which does its magic using Moralis’ Solana API. For that objective, “index.jsx” makes use of “inputHandler“, which updates the “searchInput” state variable.
Our UI logic additionally contains the “nftSearch” button. So, each time a consumer clicks on this button, the “nftSearch” operate prompts, which resets the “search” enter, after which shows the primary web page of outcomes. Moreover, it additionally calls the “apiPost” operate utilizing the “solApi/account/getNFTs” endpoint. Final however not least, the “nftSearch” operate additionally units the search ends in the “searchResults” state variable.
Subsequent, the UI logic makes use of the “loadPage” operate that units web page outcomes in order that ten NFTs are displayed per web page. This additionally triggers “setPageResult” which updates the “pageResult” state variable. Furthermore, each time “pageResult” is up to date, this renders the above-presented “NFTCard” part.
The “prevPage” and the “nextPage” capabilities are activated by the “arrow” button, which takes care of the web page navigation. Lastly, we additionally use “queryHandler“, which ensures that no matter customers enter into the filter’s entry subject is used to render related outcomes.
