Practical Advice for Solidity Developers

An average of 20,000 Smart Contracts is created every day. Over 3 Million Smart Contracts were created in November and December 2018 alone! A report shows that 60% of all Ethereum contracts have never been interacted with, less than 10% of all created contracts are unique.

Creating EVM packages with zOS!

n the last blog, we talked about building upgradable Smart Contacts using ZeppelinOS (zOS). Today, we’ll look at building EVM packages using zOS. Using Zeppelin, we can create an EVM package which can be used by other developers.

Zeppelin OS Tutorial 101

Zeppelin is all about Smart Contract development. The team has helped many developers build Smart Contracts with openzeppelin-solidity, one most downloaded web3 libraries on NPM (with over 10k downloads every week!).

Building with Kyber Network

The Kyber Protocol brings token inventories and prices on-chain, hence allowing developers to directly embed value exchanges into their smart-contracts without any technical or security overhead.

Creating Ethereum Smart Contracts via Command Line

This week we are going to create a Smart Contract using sbt-ethereum! sbt-ethereum not only allows you to create Smart Contracts, but also helps you manage your web3 projects (like one would with Truffle), though sbt’s rich command line tool. (it just makes your life easier as a web3 developer!)

Interact with Smart Contracts using the Command Line

In the last article, we learned how to create and manage wallets and addresses using sbt-ethereum, so we strongly recommend reading that article first. This week, we will learn how to interact with Smart Contracts using sbt-ethereum!

Building Applications on Compound Finance

Open Finance is on the rise. Protocols are allowing people to lend and borrow tokens trustless via smart-contracts. In the last article, we talked about MakerDao and Dai JS (also fueling open and decentralized finance [#DeFi])

Ethereum

An Intro To DaiJS

The MakerDao project created the DAI stable token. A stable token is pegged to some fiat currency, which allows it to be a unit of account. Dai is a decentralized stable coin pegged to the US Dollar value (i.e. 1 Dai = $1).

Intro to The Graph: Indexed Data for dApps

Most Ethereum dApps have two parts to their Infrastructure (Simple version): Front-end (Running in-browser) An Ethereum Node (Interface to the ETH network)

Top Libraries For Ethereum Smart Contract Developers

Today, we will list some of the most famous NodeJS libraries for building Web3 applications. These libraries are listed based on the number of downloads per month, in descending order

How the Ethereum DApp Ecosystem is Coming Together

It all started with the implementation of Satoshi Nakamoto’s white paper in 2008. That epoch was termed as Blockchain 1.0. Blockchain was thought of just as a decentralized ledger to make bitcoin transactions.

ETH-Ping — Let me ping your Ethereum Node!

At QuikNode, we always think of our customers and the problems they encounter using Web3. We recently started noticing that some were facing a problem with monitoring their Ethereum Node status.

Ethereum Hard Fork — Constantinople

Constantinople is an Ethereum hard fork, the second phase of the ‘Metropolis’ upgrade, and is part of Ethereum’s move towards a Proof-of-Stake consensus algorithm.

QuickNode Publication Launch

Going into 2019, we’re applying a focus on Education. We believe the next wave of blockchain enthusiasm, development, and adoption will be through education, and feel it’s the responsibility of those involved now, at the early stages of the tech, to facilitate it.

Ethereum Events monitoring using Eventeum

Event tracking on Ethereum can be very painful when you are building a Scalable Dapp. Today we are going to look at Eventeum, developed by Kauri Team.

Run your own Ethereum Node

With the evolution of Web3, developers are rapidly building decentralized applications on Ethereum. Building Dapps on ethereum are cool, though they come with some infrastructure setup drawbacks.
