UniCrypt: 100Xing API Blockchain Back-end Polling Speed & Halving Cost

"I can confirm that switching to QuickNode sped up our back end API blockchain polling near to 100x. This is not a ballpark figure, the speed increase was measured for long-running ethereum cron jobs and the results were exponentially better in every case."

Interacting with Ethereum MainNet using Ganache and QuickNode

When developing dApps locally, the process to interact with protocols like Compound and MakerDAO can be a tedious one. We need to fetch Smart Contracts of these protocols from Etherscan, and then initialize them with data.

Ethereum Ecosystem Statistics

Today, we will look into Ethereum statistics and see what happened in 2018–2019; what worked, what didn’t, and what’s coming next 🚀🌖🙌

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.

ERC-721 Token

The ERC-721 Token standard is the Ethereum token standard which enables Non-Fungible Tokens (NFTs) on the Ethereum blockchain. Just like the ERC-20 Token standard helps in creating fungible tokens, the ERC-721 focuses on non-fungible asset design.

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!
