In this article, we'll learn about WebHooks and how we can set-up WebHooks with QuickNode.What are WebHooks?Everything we do on the internet can be marked/considered as events and as the internet grows, these events grow in...
If you're running your own bitcoin node, there is a chance that you will want the ability to look up the balance of an address that you do not own. The first time this happens, you might create a
Sending RPC calls to get data is a common standard most blockchains follow. EtherFlow is a tool that makes it easier to send these RPC calls. This guide will explain in depth about EtherFlow, and how it...
Security is an important part of developing a resilient Web3 application. If the security of your blockchain infrastructure is compromised, it can lead to downtime for your users. We here at QuickNode recently released a new update to our security features available on...
Security is one of the most significant aspects when developing an application. If a resource like a node falls into the hands of an unauthorized individual, it can exhaust your limits and resources. In this guide, we will see how to avoid this and learn how to set up a...
If you're running Ethereum mainnet, there is chance you will want the ability to look up all of the NFTs owned by an address. The first time this happens, you might create a small script to check a particular NFT contract for ownership. This works, but then you need to...
The Solana account model is a critical part of the Solana ecosystem and can be one the hardest concepts for developers, especially ones transitioning from other blockchains, to understand. To work on the Solana blockchain efficiently, a...

Security is a crucial factor when it comes to protecting web resources. One way to protect those resources is by integrating JSON Web Tokens (JWT) in your web applications. JWT is an open standard that defines a compact way for securely transmitting information between...
Hello readers! In this tutorial we will be building out a small application that allows you to get all of the NFTs of a particular Solana wallet, and display all of the information from them on the web page. To build this out we are going to use the
ENS is the leading naming system based on Ethereum; it maps Ethereum addresses to tangible names. Today in this guide, we will learn more about ENS and How to resolve ENS domains using JavaScript library ethers.js and...
HTTP responses from blockchain methods can contain a vast amount of data and take a lot of time to receive at the client's end; compressing that data before it is being served and decompressing on the client can save a lot of time. One such compression technique is gzip...
The Ethereum network processes over one million transactions a day. These transactions originate from users wanting to transfer Ether or interact with smart contracts. In this guide, we will teach you about the Pending and Queued state of transactions on the Ethereum...
