Ethereum API

What is Ethereum?

Ethereum was the first fully programmable blockchain, and it came to life in the summer of 2015. Furthermore, the Ethereum blockchain is a decentralized public ledger that verifies and records transactions on its network. Thanks to its programmability, Ethereum became more than a digital ledger – it became the leading decentralized network. In turn, Ethereum and the network’s EVM (Ethereum Virtual Machine) also added what Bitcoin couldn’t to the foundation of Web3. Moreover, it is worth mentioning that this decentralized network was conceived by Vitalik Buterin, Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin. explains that Ethereum provides open access to digital money and data-friendly services. The latter is available for basically anyone with an internet connection, regardless of their geographical location. Ethereum is community-built technology and already “hosts” countless dapps. 

Of course, the Ethereum network also allows users to send and receive crypto assets. The latter include Ethereum’s native coin, fungible tokens, and non-fungible tokens (NFTs). This applies to tokens that follow Ethereum’s ERC standards. Essentially, anyone with an active ETH address becomes their own bank for free. These addresses in users’ wallets also serve as the keys to access all sorts of dapps running on Ethereum. Moreover, smart contracts – on-chain software – are the foundation of dapps and cryptocurrencies on this decentralized network. These contracts can trigger specific, predefined actions when certain predefined conditions have been met. They also have the power to eliminate countless intermediary services.

Ethereum’s first mover advantage formed a large, worldwide community of devs and users who believe in a decentralized future. As long as Ethereum maintains this extensive community, it will remain a properly decentralized network and the base of Web3.

What is Ether?

Ether, or ETH, is the native cryptocurrency, also known as the native coin of Ethereum. Its main purpose is to support the network’s security. However, it is used mainly to pay for transaction fees on the Ethereum network (“gas”). In addition, just like BTC (Bitcoins’ native coin), ETH may also serve as a store of value or as a form of money to pay for goods and services from merchants that accept this payment method. Furthermore, anyone with an Ethereum address can easily receive and send ETH. After all, “” refers to ether as “currency for our digital future”. This website also explains ETH as digital, global money.

At first glance, ether may not have much to do with today’s topic. However, as you develop dapps, you’ll want to execute on-chain transactions (if nothing for testing), and at that point, you will need ETH. Moreover, as you will learn herein, one of the Ethereum API endpoints focuses on fetching this native currency balance.

What is EVM?

EVM is short for Ethereum Virtual Machine. This is a Turing-complete virtual machine that runs the Ethereum chain. In a big-picture overview, we look at EVM as the entire Ethereum blockchain ecosystem with all connected computers running Ethereum clients. In that perspective, EVM is an environment in which all Ethereum accounts and smart contracts exist. Additionally, this virtual machine defines all the rules required for valid states of the Ethereum chain.

Note: If this is your first time hearing about virtual machines, make sure to check out our article explaining the question “what is Ethereum Virtual Machine?” in more detail.

What is an Ethereum API?

If you want to understand what an Ethereum API is, you need to know what APIs are in the first place. Thus, it’s worth repeating that an application programming interface (API) facilitates communication between software. It does so by translating instructions for mutual understanding. Basically, APIs provide a reliable and consistent supply of functions and requests. As such, APIs ensure reliable programming in a safe and controlled development environment.  

Furthermore, in the context of Ethereum and the decentralized web, a proper API ensures communication between blockchain nodes and backend scripts. So, as a developer, you get to utilize an Ethereum API to use existing snippets of code to fetch the data you want. This obviously makes Ethereum development significantly more accessible and time-efficient. Moreover, a proper Ethereum API eliminates the need to reinvent the wheel, and you can instead focus on the unique features of your dapp.

Ethereum API Endpoints

As you can imagine, many Ethereum API endpoints exist between all previously-listed EVM API subgroups. Consequently, we won’t be going through all of them herein. That said, you can use the Moralis docs to do that on your own. However, to make your experience as smooth as possible, let’s look at two of the most popular Ethereum API endpoints – “getNativeBalance” and “getWalletTokenBalances“. The former belongs to the “balance” subgroup, and the latter to the “token” subgroup. The following are the snippets of code that you’ll need to implement to use these two endpoints with the NodeJS framework:

  • Implementing “getNativeBalance”:
const response = await Moralis.EvmApi.balance.getNativeBalance({
  • Implementing “getWalletTokenBalances”:
const response = await Moralis.EvmApi.token.getWalletTokenBalances({

In either case, the above-presented code snippets will become active once you initialize Moralis. Hence, you’ll want to have the following lines of code at the top of your JS script:

import Moralis  from 'moralis';
import { EvmChain } from '@moralisweb3/evm-utils';

const address = 'Paste_address_here;

const chain = EvmChain.ETHEREUM;

await Moralis.start({
    apiKey: 'YOUR_API_KEY',
    // ...and any other configuration

In order to make no mistakes when implementing these lines of code, we recommend you try and get all ERC20 tokens owned by an address following our step-by-step tutorial.
