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, and so they function standardized strategies, permitting builders to seamlessly learn and write blockchain knowledge. Nonetheless, normal RPC strategies are sometimes fairly restricted, not permitting for frequent queries like “What ERC-20 tokens are pockets X holding?” To get this info, it’s essential to 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 let you question decoded, human-readable blockchain knowledge seamlessly utilizing RPC-style strategies: fetch ERC-20 balances, token costs, metadata, and way more with single calls.
However how does this work? In the event you’d wish to be taught 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?Â
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 distinct laptop. On the earth 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 function predefined strategies. These so-called RPC strategies let you seamlessly carry out varied operations, reminiscent of studying blockchain knowledge, sending transactions, and managing wallets.
Here’s a record of frequent 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 worth.
General, RPC strategies simplify interplay with blockchain networks, facilitating the easy growth of dapps and different Web3 tasks.
Exploring the Limitations of Normal RPC Strategies
Whereas RPC protocols simplify dapp growth, they arrive with important limitations that you should think about. Usually, normal RPC strategies solely present fundamental blockchain knowledge. As such, frequent RPC strategies usually are not designed to deal with queries reminiscent of, “What ERC-20 tokens does pockets X maintain?”
To acquire this type of info utilizing standard RPC strategies, builders should make a number of requests and manually compile the info. This course of is cumbersome and time-consuming, demanding appreciable growth effort and assets.
To handle 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!
Introducing Moralis’ Prolonged RPC Strategies
Our Prolonged RPC Strategies considerably enhance our node answer, delivering the identical enhanced functionalities present in Moralis’ APIs, however via RPC-style strategies. These superior strategies simplify the method of querying decoded, human-readable knowledge, streamlining your Web3 developer expertise.
What do Moralis’ Enhanced RPC Strategies embrace?

In abstract, Moralis’ Enhanced RPC Strategies considerably lengthen the capabilities of our nodes, giving you an identical enhanced knowledge you’ll get utilizing our APIs, however through RPC-style requests!
3-Step Tutorial: Tips on how to Get All Blockchain Information through Prolonged RPC Strategies
Now, with an outline of what Moralis’ Prolonged RPC Strategies entail, we’ll present you use them in follow. Extra particularly, we’ll show how one can get the token steadiness for any given pockets in three easy steps:
Enroll with Moralis & create a nodeWrite a scriptExecute the code
Step 1: Signal Up with Moralis & Create a Node
In the event 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 one in all 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 venture with the terminal command beneath:Â
npm init
As soon as initialized, set up the mandatory dependencies utilizing the offered terminal command:
npm set up node-fetch –save
npm set up moralis @moralisweb3/common-evm-utils
Subsequent, open bundle.json and add “kind”: “module” to the file:Â
After that, create an “index.js” file and insert the offered code:Â
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, 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 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 venture and run the next terminal command:
node index.js
In return, you’ll get the token balances of the required deal with, enriched with logos, spam indicators, and way more. Right here’s what it’d appear to be:
 {
//…
end result: [
{
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 normal RPC protocols that function RPC strategies. Nonetheless, conventional RPC strategies are sometimes restricted, offering solely fundamental on-chain knowledge. For example, you’ll be able to’t use standard RPC strategies to simply get the ERC-20 steadiness of a pockets. To get complete knowledge like this, you’d sometimes must make a number of requests and decode the data manually. Fortuitously, we provide a streamlined answer: Prolonged RPC Strategies!
Our Prolonged RPC Strategies ship the identical enhanced performance offered by our APIs however through RPC-style requests. With these, you’ll be able to seamlessly question ERC-20 balances, token costs, metadata, and way more utilizing single calls. Listed below are a few of our prime strategies:
eth_getTransactions: Retrieve the transactions for a pockets deal with.eth_getDecodedTransactions: Receive 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: Receive metadata for ERC-20 tokens by their addresses.eth_getNFTBalances: Retrieve NFTs held by a pockets.eth_getNFTCollections: Receive NFT collections owned by a pockets deal with.
All in all, our Prolonged RPC Strategies enhance our node answer, supplying you with entry to the identical enhanced performance that you’d get with our APIs however through RPC-style requests. In return, you’ll be able to question decoded, human-readable knowledge straight out of your Moralis nodes!
