What is a Web3 Provider?

First, you must remember that Web3 is a relatively new era. Consequently, there’s a lot of inconsistency when it comes to all sorts of terms and phrases related to blockchain technology. This also comes to light when focusing on Web3 providers. As such, you’ll see many platforms and articles out there correlate Web3 providers with Web3 node providers. However, node providers are just specific types of providers. You also have Web3 API providers, Web3 wallet and authentication providers, and other blockchain development tool providers. To better understand our definition of Web3 providers, it helps to take a look at the current blockchain tech stack:

The five layers outlined that contain dapps, Web3 and Web2 dev tools, APIs, Nodes, and Networks.

If you’d like to dive deeper into each of the five layers, use the “blockchain tech stack” link stated at the outset of this article.

Looking at the above image, you can see that there are five layers of the blockchain tech stack. Essentially, each of the above-presented five layers contributes to Web3. Accordingly, it’s technically correct to classify most Web3 dev platforms, tools, and even utility dapps as Web3 providers. Nonetheless, even every programmable blockchain (the first layer above) is a Web3 provider. After all, without blockchain networks, such as Ethereum, Solana, and BNB Chain, Web3 would not be possible.

Ultimately, a Web3 provider is a service, or a tool, that supports Web3 development and interaction with blockchains. Moreover, the most common and essential Web3 providers come in the form of Web3 node and Web3 API providers. Hence, we’ll focus on these two types in this article.

Why They are Needed

Now that you know what Web3 providers are, it’s time you learn why we need them. When it comes to blockchain network providers, they create the foundation of Web3. All other types of providers make blockchain development a whole lot simpler. Without these providers, developers would need to run their own full nodes and build an entire backend infrastructure from scratch. That said, let’s take a closer look at what purpose Web3 node providers and Web3 API providers serve. 

An illustrative image showing multiple lines connecting each other.

Why We Need Nodes and Web3 Node Providers

In case you’re not yet familiar with RPC nodes, note that they are pieces of software that connect with other nodes on the same blockchain. Also, full nodes have a complete copy of the current specific blockchain’s state. So, for instance, Ethereum RPC nodes connect to other nodes and contain the state for the Ethereum chain.  

It also helps to use a CPU analogy for blockchains: “Just like you don’t interact with the CPU when creating applications, you wouldn’t want to interact directly with the chains when building dapps“. This is where the need for nodes appears. Hence, the core purpose of Web3 nodes is to communicate with blockchains. Basically, nodes enable us to speak with the blockchain and access its data. 

Moreover, it’s worth pointing out that, technically, anyone can run a node. However, in many cases, running a node is a full-time job that requires a team for maintenance, proper backups, and much more. Accordingly, it would be extremely impractical if all Web3 developers needed to run their own nodes. With that in mind, let the Web3 node providers worry about running the nodes.

Why We Need Web3 APIs and API Providers

While nodes are great, they are still rather primitive pieces of technology. For instance, a Web3 node is not able to provide you with details, such as users’ balances. Also, nodes are only able to focus on one chain and aren’t able to cover multiple smart contracts. Furthermore, nodes only give you the raw data from the blockchain, and you would need to develop your own infrastructure to use that raw data. Fortunately, you can use Web3 APIs instead. 

APIs are sets of definitions and protocols for building and integrating applications. With that in mind, Web3 APIs support dapp development. Essentially, Web3 APIs are some of the core tools that enable dapp developers to avoid reinventing the wheel. After all, APIs offer a straightforward way for a piece of software to interact with other pieces of software. Moreover, reliable APIs enable consistent coding in a stable environment. Hence, there’s obviously a great need for high-quality Web3 API providers. Fortunately, there are already several reliable solutions at your disposal.

So, by using these Web3 providers offering APIs, you can utilize their established connections with the nodes. As such, by using a reliable API provider, you don’t have to worry about connecting to nodes. Moreover, when interacting with these providers, you effortlessly obtain all sorts of precious precompiled and precalculated on-chain data.

Basic Initialization of the Ultimate NodeJS Web3 Provider

Start by installing Moralis via your favorite package manager. Remember that the easiest way to integrate the Moralis SDK into your JavaScript project is through the npm module. 

  • If you use yarn, enter:
yarn add moralis
  • If you use npm, enter:
npm install moralis
  • If you use pnpm, enter:
pnpm add moralis

After successfully installing Moralis, you need to initialize it. To do so, use the “start” method:

import Moralis from 'moralis';

  apiKey: '<YOUR_API_KEY>',

Looking at the above lines of code, you can see that you need your Moralis Web3 API key. As such, make sure to log in to your Moralis account. By doing so, you’ll land on your admin area, where you can copy your API key:

Then, replace the “<YOUR_API_KEY>” placeholder with your actual API key. With your key in place, you can use any Moralis functionalities defined in Moralis’ NodeJS SDK references.

Furthermore, you can also set a specific configuration by calling “Moralis.start(config)“. Here’s an example of that:

  apiKey: "YOUR_API_KEY",
  formatEvmAddress: 'checksum',
  formatEvmChainId: 'decimal',
  logLevel: 'verbose'

Moreover, use the following image to find the possible options for the configuration:

Advanced Initialization of the Ultimate NodeJS Web3 Provider

As noted above, the basic initialization of the ultimate NodeJS Web3 provider will work in most instances. However, in some specific situations, you might want to install only specific packages instead of the “moralis” umbrella package. These are the currently available packages:

  • @moralisweb3/core
  • @moralisweb3/auth
  • @moralisweb3/evm-api
  • @moralisweb3/sol-api
  • @moralisweb3/evm-utils
  • @moralisweb3/sol-utils

In addition to any of the above-listed packages, you always need to install the “@moralisweb3/core” package. Let’s look at an example to clear the air. So, here are the commands to use in case you want to focus on the Moralis EVM API:

  • If you use yarn, enter:
yarn add @moralisweb3/core @moralisweb3/evm-api
  • If you use npm, enter:
npm i @moralisweb3/core @moralisweb3/evm-api
  • If you use pnpm, enter:
pnpm add @moralisweb3/core @moralisweb3/evm-api

Next, you need to register the modules to the core package at the top of your code: 

import MoralisCore from '@moralisweb3/core';
import MoralisEvmApi from '@moralisweb3/evm-api';

const core = MoralisCore.create();
// Register all imported modules to the @moralisweb3/core module

With the modules registered, you get to initialize the app in a similar manner as described in the steps covering the basic initialization of the ultimate NodeJS Web3 provider:

  apiKey: '<YOUR_API_KEY>',
  // ...and any other configuration

Following the above lines of code, you can use any functionality included in the installed modules. Of course, you also need to call the correct module in your code:

import MoralisEvmApi from '@moralisweb3/evm-api';
import { EvmChain } from '@moralisweb3/evm-utils';

const evmApi = core.getModule<MoralisEvmApi>(MoralisEvmApi.moduleName);
    chain: EvmChain.ETHEREUM,
    blockNumberOrHash: "",

Using the Ultimate Web3 Authentication Provider

At this point, you already know that you can use the power of Moralis’ Web3 Auth API by initializing the “moralis” umbrella package or the “@moralisweb3/auth” package. With that in place, you can start implementing various Web3 login solutions offered by this Web3 authentication provider. As such, you can equip your dapps with the following verification solutions:

  • MetaMask
  • WalletConnect
  • RainbowKit
  • Web3Auth
  • Magic.Link  

MetaMask and WalletConnect are the leading options when targeting experienced crypto users. However, if you wish to onboard Web2 users, you may want to focus on dynamic Web3 authentication alternatives offered by Web3Auth and Magic.Link. Moreover, if you want to understand exactly how Moralis as a Web3 authentication provider works, check out Moralis’ Auth API overview. Also, you can find demos for all supported Web3 login solutions in the Moralis docs (the “HOW TO GUIDES” section):
