Overview
Within the context of Web3, RPC refers to communication protocols that streamline the interplay between decentralized purposes (dapps) and blockchain networks. There are a number of RPC protocols, and so they characteristic standardized strategies, permitting builders to seamlessly learn and write blockchain information. Nonetheless, normal RPC strategies are usually fairly restricted, not permitting for frequent queries like “What ERC-20 tokens are pockets X holding?” To get this info, you will need to make a number of requests and join the dots your self. Thankfully, now you can circumvent these challenges with Moralis’ Prolonged RPC Strategies.
Our Prolonged RPC Strategies let you question decoded, human-readable blockchain information seamlessly utilizing RPC-style strategies: fetch ERC-20 balances, token costs, metadata, and way more with single calls.
However how does this work? Should you’d prefer to study extra, be a part of us on this information as we lay all of it out for you. Let’s dive straight in!
What are RPC Strategies?
RPC, quick for “Distant Process Name,” refers to communication protocols that enable one software program system to name and request a service from one other software program system on a special laptop. On the planet of crypto, RPC allows dapps and different Web3 platforms (shoppers) to work together with a blockchain community (server).
There are standardized protocols, one instance being JSON-RPC, that characteristic predefined strategies, reminiscent of eth_getUncleByBlockHashAndIndex. These so-called RPC strategies let you seamlessly carry out varied operations, reminiscent of studying blockchain information, sending transactions, and managing wallets.
Here’s a record of frequent RPC strategies for Ethereum:
eth_blockNumber: Returns the variety of the newest block.
eth_call: Executes a brand new message name.
eth_chainId: Returns the present chain ID.
eth_getBalance: Returns the steadiness of an account.
eth_gasPrice: Returns the present gasoline worth.
Total, RPC strategies simplify interplay with blockchain networks, facilitating the easy improvement of dapps and different Web3 tasks.
Exploring the Limitations of Customary RPC Strategies
Whereas RPC protocols simplify dapp improvement, they arrive with vital limitations that it is advisable to contemplate. Usually, normal RPC strategies solely present fundamental blockchain information. As such, frequent RPC strategies will not be designed to deal with queries reminiscent of, “What ERC-20 tokens does pockets X maintain?”
To acquire this sort of info utilizing typical RPC strategies, builders should make a number of requests and manually compile the info. This course of is cumbersome and time-consuming, demanding appreciable improvement effort and assets.
To deal with these challenges, Moralis introduces Prolonged RPC Strategies. However what precisely are these strategies, and the way do they profit builders?
Discover out within the subsequent part!

In abstract, Moralis’ Enhanced RPC Strategies considerably prolong the capabilities of our nodes, giving you a similar enhanced information you’d get utilizing our APIs, however by way of RPC-style requests!
3-Step Tutorial: Methods to Get All Blockchain Information by way of Prolonged RPC Strategies
Now, with an outline of what Moralis’ Prolonged RPC Strategies entail, we’ll present you easy methods to use them in follow. Extra particularly, we’ll exhibit how one can get the token steadiness for any given pockets in three easy steps:
Enroll with Moralis & create a node
Write a script
Execute the code
Step 1: Signal Up with Moralis & Create a Node
Should you haven’t already, click on the “Begin for Free” button on the prime proper to enroll with Moralis:
When you log in, go to the “Nodes” tab and click on the “+ Create Node” button:
Choose “Ethereum,” adopted by “Mainnet,” and hit “Create Node”:
Copy considered one of your node URLs and preserve it for now, as you’ll want it within the subsequent step:
Step 2: Write a Script
Open your most well-liked IDE, arrange a brand new folder, and initialize a undertaking with the terminal command beneath:
npm init
As soon as initialized, set up the required dependencies utilizing the supplied terminal command:
npm set up node-fetch –save
npm set up moralis @moralisweb3/common-evm-utils
Subsequent, open bundle.json and add “sort”: “module” to the file:
After that, create an “index.js” file and insert the supplied code:
import fetch from ‘node-fetch’;
const choices = {
methodology: ‘POST’,
headers: {
settle for: ‘utility/json’,
‘content-type’: ‘utility/json’
},
physique: JSON.stringify({
“jsonrpc”: “2.0”,
“id”: 1,
“methodology”: “eth_getTokenBalances”,
“params”: [
{
“address”: “0xcB1C1FdE09f811B294172696404e88E658659905”,
}
]
})
};
fetch(‘YOUR_NODE_URL’, choices)
.then(response => response.json())
.then(response => console.log(response))
.catch(err => console.error(err));
From right here, it is advisable to make some minor configurations. First, add the node URL you copied throughout step one by changing YOUR_NODE_URL. Subsequent, configure the handle parameter to suit your question:
That’s it for the code. All that is still now could be to execute the script.
Step 3: Execute the Code
To run the code, navigate to the foundation folder of the undertaking and run the next terminal command:
node index.js
In return, you’ll get the token balances of the required handle, enriched with logos, spam indicators, and way more. Right here’s what it’d appear to be:
{
//…
outcome: [
{
token_address: ‘0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2’,
