Overview
Whether or not you’re constructing an Ethereum-based decentralized trade (DEX), cryptocurrency pockets, portfolio tracker, or some other Web3 venture, you want a straightforward option to question ERC-20 tokens, transactions, and so on., from the blockchain. Nevertheless, that is simpler stated than achieved. And with a number of methods to question blockchain knowledge, how do you discover the most suitable choice?
On this information, we’ll introduce you to the simplest option to question and combine Ethereum blockchain knowledge into your tasks. So, whether or not you’re seeking to prototype your personal Web3 venture or scale an present dapp, this learn is for you. Let’s dive straight into it!
What’s Ethereum Information?
Ethereum knowledge – additionally sometimes known as ”Ethereum on-chain knowledge” – is all of the publicly accessible info saved on the Ethereum blockchain. With this knowledge, it’s potential to confirm transactions, monitor the motion of belongings, and achieve in-depth market insights. As such, the flexibility to question blockchain knowledge is an important a part of constructing dapps and different Web3 tasks on Ethereum!
Ethereum blockchain knowledge will be divided into three predominant classes:
Transaction Information: Transaction knowledge is details about every Ethereum transaction. This contains sender and receiver addresses, transaction quantities, charges, and extra. Good Contract Information: Good contract knowledge refers to all of the details about sensible contracts deployed on Ethereum, together with a contract’s code, logs, state, and occasions. Block Information: Block knowledge is all of the details about every block within the Ethereum chain. This contains info equivalent to hashes, transactions, miner charges, time stamps, and far more.
All in all, Ethereum knowledge refers back to the publicly accessible info saved on the blockchain, together with transaction, sensible contract, and block knowledge!
How Do You Get Information from the Ethereum Blockchain?
It’s potential to question the Ethereum blockchain in quite a few alternative ways. Under, we’ll discover three distinguished examples:
Run a Node: One possibility for querying the Ethereum blockchain is to run a node your self. In doing so, you may straight work together with the Ethereum blockchain to question transactions, ERC-20 tokens, and extra. Block Explorers: It’s additionally potential to leverage block explorers, that are platforms that will let you seamlessly browse all transactions saved on Ethereum. For Ethereum, the go-to alternative is Etherscan. Web3 APIs: You too can use Web3 API suppliers to question the Ethereum blockchain. A Web3 API – brief for ”utility programming interface” – is a group of guidelines, strategies, and protocols that will let you work together with a blockchain community.
Whereas you should use nodes, block explores, and Web3 APIs to question the Ethereum blockchain, these three choices have their very own benefits and drawbacks. For instance, working a node requires an underlying infrastructure, which will be bothersome to arrange. Moreover, whereas block explores provide you with an intuitive interface to learn blockchain transactions, they’re not designed for integrating knowledge into dapps.
As such, with regards to Web3 growth, your only option is to leverage a Web3 API supplier! However which Web3 API supplier is the most effective? For the reply to this query, be part of us within the following part as we introduce you to Moralis!

Tutorial: The right way to Question Ethereum Blockchain Information in 3 Steps
We’ll now cowl a short tutorial exhibiting you methods to name the assorted endpoints of Moralis. As such, when you comply with alongside, you’ll quickly know methods to question the Ethereum blockchain your self for ERC-20 tokens, transactions, NFT balances, and extra!
Nevertheless, for this walkthrough, we’ll be utilizing the getWalletTokenBalances() endpoint for example. And we’ll present you methods to question the Ethereum blockchain in three steps:
Get a Moralis API KeyWrite a ScriptRun the Code
Nevertheless, earlier than continuing, you need to cope with a couple of conditions!
Stipulations
You’ll be able to question Ethereum blockchain knowledge with Moralis utilizing a number of completely different programming languages, together with Python, Go, and so on. Nevertheless, for this tutorial, we’ll use JavaScript and Node.js. As such, when you haven’t already, guarantee you have got the next prepared:
Step 1: Get a Moralis API Key
If you happen to haven’t already, join with Moralis by clicking on the ”Begin for Free” button on the high proper of Moralis’ homepage:
With an account at hand, go to the ”Settings” tab, scroll all the way down to the ”API Keys” part, and replica your key:
Maintain it for now, as you’ll want it within the subsequent step!
Step 2: Write a Script
Open your IDE, arrange a brand new folder, and initialize a venture utilizing the next terminal command:
npm init
Subsequent, set up the Moralis SDK with the next terminal enter:
npm set up moralis @moralisweb3/common-evm-utils
You’ll be able to then open your ”package deal.json” file and add ”sort”: ”module” to the listing:
From right here, create an ”index.js” file and add the next code:
import Moralis from ‘moralis’;
attempt {
await Moralis.begin({
apiKey: “YOUR_API_KEY”
});
const response = await Moralis.EvmApi.token.getWalletTokenBalances({
“chain”: “0x1”,
“handle”: “0x1f9090aaE28b8a3dCeaDf281B0F12828e676c326”
});
console.log(response.uncooked);
} catch (e) {
console.error(e);
}
You then must configure the code by changing YOUR_API_KEY, which you copied earlier, and configure the handle parameter to suit your question:
That’s it; all that continues to be from right here is working the code!
Step 3: Run the Code
Open a brand new terminal and run the command beneath to execute the script:
node index.js
In return, you’ll get a response containing an array of all tokens held by the pockets in query. It is going to look one thing like this:
[
{
“token_address”: “0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48”,
“symbol”: “USDC”,
“name”: “USD Coin”,
“logo”: “https://cdn.moralis.io/eth/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48.png”,
“thumbnail”: “https://cdn.moralis.io/eth/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48_thumb.png”,
“decimals”: 6,
“balance”: “10”,
“possible_spam”: false,
“verified_contract”: true
},
//…
]
That’s it! Querying Ethereum knowledge doesn’t should be more difficult than that. From right here, you may comply with the identical steps and easily swap the endpoints and parameters to question transactions, NFTs, or different Ethereum knowledge!
