NFTs, non-fungible tokens, have taken the online world by storm ushering in the proclamation of a new world-wide web... web3.

For most, NFTs mean profile pictures (pfps). 🐵

This isn't the most practical use case, even if it is a lot of fun

Even if you wanted to create useful NFTs, it’s not easy to get started.

Since the tooling is still being developed, it can be confusing as to where to get started. It also doesn't help that there's a paradigm shift with app development from web2 to web3.

Here be dragons 🐉

This course is here to get you through that initial learning curve and frustrating lack of answered questions and good documentation.

Through building this project you will learn the general development lifecycle of NFT smart contracts and dApps giving you the skills to start your own projects.

By the end of this course, you will be able to do the following

- Use the OpenZeppelin Solidity library to create NFT smart-contracts
- Deploy smart contracts to Ethereum testnets
- Host static assets on IFPS
- Create a React dApp that interacts with your smart-contract API
- Confirm a wallet owns an NFT

This course will help you build a ticketing and proof-of-attendance service complete with wallet QR code scanning, using Solidity and React

Blockchains revolutionized fundraising for open-source software, but not everything worked right from the start. In fact, ICOs of the 2016-2018 era were often horribly broken mechanisms that allowed founders to cash out before delivering any products. Many lessons have been learned since, with today’s projects having a working product before launching a token and distributing it to incentivize usage and decentralize governance.

NFTs are proving to be another clear product-market-fit for crypto, but they are experiencing their own growing pains. The life of every NFT begins in an NFT launch (also sometimes called a mint or drop). An NFT launch is where a new collection is first created, sold, and distributed to buyers, who then decide to hold or trade it in secondary markets.

Like any item that goes on sale for the first time, NFT launches face the challenge of pricing something that has never had a price before. But unlike most other sales, they have the added difficulty of taking place in a highly adversarial environment full of idiosyncrasies that already alienate inexperienced users—a public blockchain. As a result, developers have to design mechanisms that are efficient and robust to exploitation.

This article starts with real-world examples of launches that empirically hurt their users to identify what goals a good launch should satisfy. Next, we deconstruct the idea of a launch into individual steps, exploring the design space for each of them. Finally, we provide a reference implementation of what we think is one well-designed launch mechanism for the community to use and build on.

This article starts with real-world examples of NFT launches and explores the design space for well-designed launch mechanisms for the community to use and build on.

A Guide to Designing Effective NFT Launches


My Twitter feed has tons of avatar profile pictures, articles are coming out daily showcasing some large NFT sales, and people are earning money with their in-game creatures...

I guess this means it's time to go down the NFT rabbit hole. So let's get to it!

This article introduces NFT's and guides you through creating your NFT collection on Ethereum using solidity.

Create your own NFT collection on Ethereum w/Solidity


NFTs, as unique items on the blockchain, has a URI that points to data containing the metadata & the corresponding visuals. This URI can be an HTTP link, pointing to a video or image hosted on a normal server, or other services like IPFS (hash-based addresses), or Arweave (incentivized hosting of hash-based content).

There is another way, however, a format that's become increasingly popular: the usage of a data URI. These URIs contain all the information within it. There is thus no server at the other end. Using data URIs has allowed NFT creators to experiment with putting all the content related to an NFT 'on-chain'. It adds a vector of permanence to the art. If Ethereum continues, it does not need ancillary infrastructure to support it. A common format, currently, is to store the NFT visuals as SVG in the data URI, since most browsers are able to natively parse it.

It's fun, and due to some of the constraints of smart contract coding (limited execution & expensive storage), it becomes in itself a game of gas golf, trying to pack as much as one can into the architecture to create dynamic art that will live (currently) forever on Ethereum.

Store NFT visuals as SVG in the data URI, so it does not need ancillary infrastructure to support it.

ENS now supports NFT avatars for your profile.

What this means is you can now set an NFT you own as the avatar of your ENS profile, and dapps can then display it alongside your ENS name.

buddy buddy tag NFTs are a brand new project put together to experiment with completely on-chain generative development. you get one for yourself, for your friend, forever😹. as of this point, there are 13 minted tags, with 7 of them confirmed!

What does that mean? well, buddy buddy tags are on-chain, generative NFTs that require a minter to submit a buddy’s address when minting. the minter receives a randomized set of emojis along with his wallet address and his buddies. think of it like a fortune cookie, you don’t know what you’ll draw, and the interpretation is up to the minter and his buddy.

Recently I took a deep dive into the Crypto World. Especially on DeFi and Smart Contracts. So I did what probably every other developer has done that started working on the Block Chain. I minted my own NFT. Particularly an ERC-721 Token. This is an article I really wish I had a few weeks ago.

Session keys are an incredible powerful tool for building consumer-ready applications through their complete removal of popups for end-users. This tutorial leverages Particle Network's AA SDK and Smart Wallet-as-a-Service to showcase the process of implementing session keys (alongside social logins) within your own application (which only takes roughly 7 minutes, around 100 lines of code).

In this video, we will dive into the essential checklist that will guide you through the crucial aspects of a successful NFT launch. 

From a tech perspective, you have to consider multiple things: network, standard (erc721 vs erc1155), royalties, code verification, contract access controls, token distribution and more.

That's why I prepared checklist of stuff to consider before releasing NFT. You may watch it on my Youtube channel below:
