Our whole universe was in a hot, dense state
Then nearly fourteen billion years ago, expansion started, wait
The Earth began to cool
The autotrophs began to drool
Neanderthals developed tools
We built a wall (We built the pyramids)
Math, science, history, unraveling the mystery
That all started with the Big Bang (Bang)
Recognize the lyrics above?
Fans of the big bang theory tv series would have a nostalgic smile decorating their faces right now.
Whether you are a fan or not though, everyone will be carried along on this exciting performance of an article.
The Big Bang Theory is a comic tv series that aired from 2007 to 2019 about a friend group of six science nerds, who navigate many life experiences in the academic world and eventually emerge victorious in their individual professions. It’s a fitting inspiration for this story in which I will carry you along as your loyal tech friend with a wacky sense of humor (😎) to navigate an exceptionally useful blockchain platform that could completely revolutionize your web 3 development ideology.
Getblock is a real big bang in the blockchain universe!
So you’re a tech guy/babe looking to get into he web 3 space. You already have some experience. You can clearly explain the front end and backend dichotomy. Maybe you already have some web apps hosted or some mobile apps uploaded on application stores. But you still want more. The cyberspace has been agog with tales of web 3 technology and the great future it promises. Crypto billionaires are already being created and you want to cash in on the technology now that it’s still young. You’ll love your share of the blockchain pie right? Well, me too, let’s share the experience.
Now, you’re getting into web 3. Have you learned solidity? No? That’s the language you use to write your smart contracts. Smart contracts are classes (package of code including certain data and functions that work on them) which outline the rules/algorithms governing the operations of a web 3 project. They are coded on a an editor and are uploaded to the blockchain to function (e.g., same way you would upload web 2 code to a server).
The blockchain represents the backend of web 3 technology. Not fully clear on this? No problem, back to the basics. Most software applications are divided into two parts for easy operation. The frontend and the backend. The frontend represents the user interface which allows users to easily interact with the technology. The backend represents the problem solving and data management side of the technology where most of the heavy lifting in the software application is handled. The backend is usually stored on an online server and an Application Package Interface (API) is used to connect the frontend on the users phone to the backend on a server somewhere. This is the basic architecture of a software application.
However, due to the great difficulties of building a backend from scratch, companies arouse which offered backend services like cloud platforms so developers can easily assemble the frontend code and connect to the ready made backend platforms available for use, considerably simplifying the development process.
That’s web 2 technology though were the backend is handled by centralized servers. In web 3 the blockchain itself (a decentralized global database) acts as the backend and the backend code which does the data management work are the smart contracts that users write and upload to the smart blockchain.
Usually, users can download a blockchain software on their device and use it in building web 3 applications but the backend as a service option which revolutionized web 2 technology has also taken hold in the web 3 space. Just like in web 2, backend as a service platforms simplify the development process by handling all the heavy lifting associated with data management while the developer focuses on developing a frontend and writing the smart contracts. Web 3 gateways (libraries, APIs and Remote Procedure Call (RPC) providers then connect this frontend created with the backend as a service platform. This is where Getblock comes in.
Blockchain technology has permeated the entire globe and almost everyone on the internet is spewing crypto slangs to sound cool. Great if you ask me. Asides the awesome PR though, people still have to understand how to navigate the technicalities of blockchain technology and utilize the system for maximum benefit. The blockchain, however exciting it sounds is a rather technical and recent technology which a lot of people around the world are yet to fully understand hence, they can’t benefit. This complicated access to the underlying infrastructure triggered the development of web 3 gateways which are explained below;
- Web 3 libraries are collections of code which are integrated in the crypto software to easily connect to the blockchain.
- Web 3 APIs are data structure keywords to easily access data and functionality from the blockchain.
- RPC providers grant access to RPC nodes which are blockchain nodes that coordinate other blockchain infrastructure.
Though often marketed as an RPC provider, Getblock is a better defined as a robust web 3 provider platform, handling both API and RPC services online for easy access and management of blockchain functionalities by developers.
GetBlock is a full-node-as-a-service platform that provides instant access to over 50 blockchain protocols through unified APIs. It is designed for developers who want to connect to major blockchain networks without running and maintaining their own infrastructure. GetBlock Web3 RPC Provider is the best service for connecting to blockchain nodes and the right solution to expand the capabilities for your web3 projects.
GetBlock is an ideal solution for developers seeking speed, scalability, and multi-chain access with minimal infrastructure overhead. It’s trusted by startups and enterprises alike to power Web3 products across ecosystems.

Learn how to set up custom RPC URL on MetaMask for faster, more reliable, and secure blockchain interactions.
MetaMask is a blockchain wallet available as a mobile application and a browser extension. It allows you to interact with Ethereum-based decentralized applications (dApps) directly from your browser.
Using GetBlock nodes with MetaMask makes your blockchain experience faster and more reliable than using default RPCs:
- Connect directly to trusted nodes for secure transactions.
- Enjoy quicker transactions and smoother dApp interactions.
- Experience less downtime, even during busy network periods
This step-by-step tutorial will guide you through connecting GetBlock’s powerful nodes to your MetaMask wallet.
Before you start
Set up your wallet
If you don’t already have MetaMask, download and install it from the official website: https://metamask.io/download.
MetaMask extension is officially supported on Chrome, Brave, Firefox, Microsoft Edge, and Opera browsers.
Get a custom RPC URL
Generate a JSON-RPC URL for the selected network from your GetBlock account and copy it.
Generate an RPC URL for MetaMask
Rename your endpoints to clearly indicate their purpose.
Add GetBlock RPC to an existing network
If the network is already in your list but uses a default RPC provider, you can switch to GetBlock by following these steps:
- Click on the current network name in MetaMask to open the dropdown of networks.
- Find the network you want to edit and click the settings menu next to it. Select ‘Edit’.
- Open the ‘Default RPC URL’ dropdown and select ‘Add RPC URL’.
- Paste the JSON-RPC endpoint URL from your GetBlock account (
https://go.getblock.io/)./ - Name the new RPC URL for easier identification.
- Click ‘Add URL’, then ‘Save’ to confirm.
You can now switch between RPC URLs for that network as needed.
Add a new network to MetaMask
If the network isn’t in your list, you can add it as a custom network. For this example, we will add the Polygon zkEVM to MetaMask.
- Click on the current network name.
- Select ‘Add a custom network‘.
- Fill in the required fields:
Field Description Example
RPC URL The network’s JSON-RPC URL from your GetBlock account https://go.getblock.io/
Chain ID The ID of the network 1101
Network name Fetched automatically based on Chain ID Polygon zkEVM
Currency symbol Suggested automatically based on Chain ID ETH
Block explorer URL Optional field https://zkevm.polygonscan.com/
- Click ‘Save’, and the custom network will be added and selected as default.
You can get the Chain ID of an EVM-compatible network (e.g. Polygon zkEVM) sending a request to your endpoint with this curl command:
Copy
curl --location --request POST 'https://go.getblock.io//' \
--header 'Content-Type: application/json' \
--data-raw '{
"jsonrpc": "2.0",
"method": "eth_chainId",
"params": [],
"id": "getblock.io"
}'

Getblock RPC API for Dapp Development
Firstly; What is RPC in web3? This is also known as Remote Procedure Call; it is a communication mechanism that is used to interact with the blockchain networks particularly the Ethereum and other decentralized networks. In this context, RPC allows clients to communicate with the Ethereum nodes to query blockchain data, send transactions and execute smart contracts. RPC Nodes expose an RPC interface, allowing external entities to communicate directly with the nodes. Whereas APIs provide a simplified, high-level interaction with blockchain networks, RPC nodes offer raw access to blockchain functions.
Getblock is a practical choice for Web3 projects seeking a balance between cost, ease of use, and reliable access to blockchain networks. With this tool you can connect your dApp to mainnet and testnet networks with APIs: JSON-RPC, REST, WebSocket, GraphQL, etc.
