Overview
Within the context of Web3, RPC refers to communication protocols that streamline the interplay between decentralized functions (dapps) and blockchain networks. There are a number of RPC protocols, they usually function standardized strategies, permitting builders to seamlessly learn and write blockchain knowledge. Nevertheless, customary RPC strategies are usually fairly restricted, not permitting for widespread queries like “What ERC-20 tokens are pockets X holding?” To get this data, you should make a number of requests and join the dots your self. Fortuitously, now you can circumvent these challenges with Moralis’ Prolonged RPC Strategies.
Our Prolonged RPC Strategies mean you can question decoded, human-readable blockchain knowledge seamlessly utilizing RPC-style strategies: fetch ERC-20 balances, token costs, metadata, and rather more with single calls.
However how does this work? When you’d prefer to study extra, be 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 permit 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 (purchasers) to work together with a blockchain community (server).
There are standardized protocols, one instance being JSON-RPC, that function predefined strategies. These so-called RPC strategies mean you can seamlessly carry out numerous operations, reminiscent of studying blockchain knowledge, sending transactions, and managing wallets.
Here’s a record of widespread RPC strategies for Ethereum:
eth_blockNumber: Returns the variety of the latest 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 fuel value.
General, RPC strategies simplify interplay with blockchain networks, facilitating the easy improvement of dapps and different Web3 initiatives.
Exploring the Limitations of Customary RPC Strategies
Whereas RPC protocols simplify dapp improvement, they arrive with vital limitations that you should take into account. Usually, customary RPC strategies solely present fundamental blockchain knowledge. As such, widespread RPC strategies aren’t designed to deal with queries reminiscent of, “What ERC-20 tokens does pockets X maintain?”
To acquire this sort of data utilizing standard RPC strategies, builders should make a number of requests and manually compile the information. This course of is cumbersome and time-consuming, demanding appreciable improvement effort and sources.
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!

3-Step Tutorial: Tips on how to Get All Blockchain Information through Prolonged RPC Strategies
Now, with an summary of what Moralis’ Prolonged RPC Strategies entail, we’ll present you methods to use them in apply. Extra particularly, we’ll show how one can get the token steadiness for any given pockets in three easy steps:
Join with Moralis & create a node
Write a script
Execute the code
Step 1: Signal Up with Moralis & Create a Node
When you haven’t already, click on the “Begin for Free” button on the high 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 one in all your node URLs and maintain it for now, as you’ll want it within the subsequent step:
Step 2: Write a Script
Open your most popular IDE, arrange a brand new folder, and initialize a undertaking with the terminal command beneath:
npm init
As soon as initialized, set up the mandatory dependencies utilizing the supplied terminal command:
npm set up node-fetch –save
npm set up moralis @moralisweb3/common-evm-utils
Subsequent, open package deal.json and add “kind”: “module” to the file:
After that, create an “index.js” file and insert the supplied code:
import fetch from ‘node-fetch’;
const choices = {
technique: ‘POST’,
headers: {
settle for: ‘software/json’,
‘content-type’: ‘software/json’
},
physique: JSON.stringify({
“jsonrpc”: “2.0”,
“id”: 1,
“technique”: “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, you should make some minor configurations. First, add the node URL you copied throughout step one by changing YOUR_NODE_URL. Subsequent, configure the deal with parameter to suit your question:
That’s it for the code. All that continues to be now’s to execute the script.
Step 3: Execute the Code
To run the code, navigate to the basis folder of the undertaking and run the next terminal command:
node index.js
In return, you’ll get the token balances of the desired deal with, enriched with logos, spam indicators, and rather more. Right here’s what it would appear like:
{
//…
outcome: [
{
token_address: ‘0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2’,

Abstract: Prolonged RPC Strategies – Get All Blockchain Information through RPC Strategies
RPC stands for “Distant Process Name,” and within the context of Web3, it refers to communication protocols that permit dapps to speak with blockchain networks. There are customary RPC protocols that function RPC strategies. Nevertheless, conventional RPC strategies are sometimes restricted, offering solely fundamental on-chain knowledge. As an example, you may’t use standard RPC strategies to simply get the ERC-20 steadiness of a pockets. To get complete knowledge like this, you’d usually have to make a number of requests and decode the knowledge manually. Fortuitously, we provide a streamlined answer: Prolonged RPC Strategies!
Our Prolonged RPC Strategies ship the identical enhanced performance supplied by our APIs however through RPC-style requests. With these, you may seamlessly question ERC-20 balances, token costs, metadata, and rather more utilizing single calls. Listed below are a few of our high strategies:
eth_getTransactions: Retrieve the transactions for a pockets deal with.
eth_getDecodedTransactions: Acquire detailed transaction historical past for a pockets deal with.
eth_getTokenBalances: Retrieve ERC-20 token balances for a pockets deal with.
eth_getTokenPrice: Fetch present costs for ERC-20 tokens.
eth_getTokenMetadata: Acquire metadata for ERC-20 tokens by their addresses.
eth_getNFTBalances: Retrieve NFTs held by a pockets.
eth_getNFTCollections: Acquire NFT collections owned by a pockets deal with.
All in all, our Prolonged RPC Strategies enhance our node answer, providing you with entry to the identical enhanced performance that you’d get with our APIs however through RPC-style requests. In return, you may question decoded, human-readable knowledge straight out of your Moralis nodes!
