So, create your account today and kickstart your blockchain development! 

What is an SDK?

Before exploring the Moralis SDK and why it’s the most desirable option in comparison with other Web3 SDKs, we need to cover some basics. Let’s start by answering the question, “what is an SDK?”. In case you don’t know yet, SDK stands for “Software Development Kit”. You’ll often also hear the word “devkit” being used, which means the same thing. SDK refers to a set of tools or items (a kit) that particular software development requires. This includes the kit pieces, assembly instructions, the tools needed to put the pieces together, etc. 

Essentially, a proper SDK provides a developer with a set of tools, libraries, code samples, processes, relevant documentation, and specific guidelines. All of which enables developers to create software applications (dApps in our case) on a specific platform.

Furthermore, SDKs are essentially the origination sources for basically every program a user interacts with. This includes web browsers to video games, and more or less everything in between. 

What is an API?

We know that you are eager to learn more details about the Moralis SDK; however, based on our experience, there is a lot of confusion among beginners when it comes to APIs and SDKs. Many people tend to mix up those two concepts. Thus, let’s make sure that we all know the difference between APIs and SDKs. Since we’ve covered what an SDK is, it’s time to focus on what an API is.

API stands for “Application Programming Interface”. An API is an interface that enables software to interact with other pieces of software. It enables different instruction sets to be translated or transferred for mutual understanding. Furthermore, APIs allow for consistency (or consistent coding) in a stable environment. That way, all replicable functions can be delivered consistently and with predictability on every request.

For instance, a simple piece of software, such as a browser, uses various API sets. That way, it converts users’ commands into functions, requests data from servers, renders that data into a proper format for the user, validates the performance of their requests, and much more. Web APIs have a slightly different function – they allow for interaction among disparate systems, typically for specific use cases. A web API is essentially a set of instructions (just like the PC API); however, it’s based in the web sphere. For example, you may be familiar with the Moralis NFT API, which allows you to create an NFT game in mere minutes.


Put simply, SDKs are superior to APIs. What’s interesting, though, is that an SDK often contains APIs. A good analogy is offered by looking at squares and rectangles. You surely know that the concept of “rectangles” can include both rectangles and squares, while “squares” only include squares. In this case, SDKs are rectangles and APIs squares. As such, every time an SDK is used to create an app that has to communicate with other apps, it surely includes an API for that purpose. In case you’re not much of a geometry fan, you can view the SDK as the house and all of its content, while the APIs are the telephone lines allowing for communication in and out of the house.

The Moralis’ SDK – the Ultimate Web3 SDK

Blockchain-based technologies could well represent the next digital paradigm shift, and is finding its way into a growing number of companies. In fact, this disruptive and world-changing tech is taking over the world at an incredible pace. As such, every Web3 developer is highly sought-after. 

Unfortunately, the majority of dApp developers take the complicated and difficult road by trying to reinvent the wheel. They usually make the mistake of starting by connecting to an RPC node. Sadly, they don’t know that RPC nodes are primitive, low-level tech, with horrible databases that can’t do filtering nor aggregation. Moreover, building the infrastructure around an RPC node requires a massive codebase. This makes things highly complicated and extremely time-consuming. Not to mention that the results (or end products) typically aren’t great either. 

Fortunately, you came to the right place. By learning about Moralis’ SDK, the leading Web3 SDK, you’ll be able to “fly on the wings” provided by the developers behind Moralis. Moreover, the Moralis SDK solves the tedious backend coding with its plug-and-play functionality. The goal of Moralis is to make Web3 development as simple as possible, like offering functionality with a single line of code. The tech for building great dApps is already here – what’s missing is capable tools to take advantage of the tech. This is where Moralis comes in. 

The Moralis SDK – What Every dApp Needs

When developing dApps, there are certain functionalities that most dApps require. These include the following:

  • Logging in users. 
  • Fetching balances (coins, NFTs, tokens).
  • Fetch transactions.
  • Fetching smart contract events.
  • Delivering real-time alerts.
  • Building some sort of index to change and build the database on on-chain events.
  • Sending transactions.
  • Interacting with smart contracts.

Of course, there are many other functionalities available. However, the listed ones properly summarize about 90% or more used in dApps. Why 90%? Well, most dApp developers that take the conventional path of reinventing the wheel (as explained previously) spend over 90% of their time implementing the functionalities mentioned above.

So, how would you like to cut out the vast majority of your development time? Well, by using the right tools, you can. As such, you get to finish your Web3 applications markedly quicker and also deliver a much better user experience since you can focus basically all of your attention and resources on creating a stunning frontend. This resource-saving aspect is where the real power of Moralis’ SDK shines. Thus, you see why it is one of the premier Web3 SDKs. In case you need some more info about the Moralis SDK and why it’s the best Web3 SDK, make sure to watch the following video:

Getting Going with the Moralis Web3 SDK
