One day I spotted a cute pixel NFT and I instantly fell in love with the cute animated characters. I was early to the game but didn’t have much ETH in my wallet, so I bought just one.

I didn’t pay much attention to my new NFT until it hatched during the reveal event. I then spent the whole day looking at all the new characters that had been generated, digging around to figure out how everything was working and sketching out what I thought was the minting process, but everything seemed to link back to the solidity contract and it looked scary.

A few days passed by and I woke up one morning feeling code-brave. Cracked open Google and started trying to understand a few solidity contracts.

I failed.

In the end, I asked Lynq to help me dig into things and together we finally started to make some headway towards understanding NFTs. And it wasn’t until I worked my way through this article that everything really clicked.

Exclusive – The Cool Kids were noticeably absent from the Hip Hop space for a few years as they embarked on a self-imposed hiatus. But in 2017, Chuck Inglish and Sir Michael Rock returned with a vengeance and dropped Special Edition Grand Master Deluxe, elating their fans in the process.

While the Chicago-Detroit duo released several projects in the interim, they officially dropped their fourth studio album on Friday (March 3). Titled Before Shit Got Weird, the 19-track project serves as the inaugural installment of The Cool Kids’ triple album. Ahead of its release, Chuck Inglish and Sir Michael Rocks delivered its first non-fungible token (NFT) called “Pre-Weird. ” The NFT sold out in roughly 45 minutes, proving just how desperate The Cool Kids’ fans were for anything new from the trailblazing artists.

“I have not released an NFT like that before, so I didn’t really know what to expect and didn’t know how our fanbase would respond,” Sir Michael Rocks tells HipHopDX. “So I was surprised to see it just fly so quick like that. So that’s tight. I’m really happy about it

To Sir Michael Rocks, that was a promising sign The Cool Kids are in high demand. Some people bought it simply because it was affiliated with the group.

“That definitely gives me that idea because a lot of people weren’t even sure what the NFT was or what it did,” he explains. “It does some cool shit, actually. People were like, ‘Man, I just bought it anyway because I just wanted to fucking tap in with you guys and be a part of the rollout. ’ Once they saw the actual perks and utility that it gives you, that was just an added bonus, I’m sure. So it’s looking like the sentiment is there. I think people are ready for us

To create the NFT, The Cool Kids partnered with Quincy Jones-backed platform and green Web3 company OneOf. Interpreted from Before Shit Got Weird, the “Pre-Weird” collection is comprised of unique artworks of isometric shapes representing The Cool Kids’ home cities, as well as their visions of alternate realities and inspiration from their upbringing.

Purchasers were also granted access to an exclusive track called “Captain Planet Rock” as well as chances to win concert tickets, meet and greets, unique merch and other experiences both virtual and in real life.

When asked if the single was a nod to Afrika Bambaataa, Chuck Inglish says, “I would say that there is a deep emotional tie to that, but it was just the high energy. ‘Planet Rock’ was like a national anthem for rap music and then we were bringing it to current times.

“We did that song in late 2017, early 2018 when we started the album and it was so good, but it didn’t fit on anything, and it felt like just a drop of rain or a moment in time. I wanted to give something that sounded like an exclusive unreleased track instead of something we just didn’t put on the album or shit that didn’t make it

Chuck Inglish is amazed they’re even in the NFT space at all, calling it “a trip in general. ” But they wanted to make sure to give their fans much more than a useless JPEG. Instead, they aimed to cultivate an entire Cool Kids world.

“JPEG is the buy-in,” he adds. “So we are like, ‘OK, we make music. We’re not making no god damn JPEGs, what can we offer?’ And it’s like, ‘We can give you a world that you can exist in. ’ And then in that world, y’all can build a community

Mikey jumps in with, “The image you see for the NFT is basically that’s the world that we created with the album. If you listen through the skits, songs, interludes and stuff, they’re all taking place in this space in time, which would be that city that you see on the NFT pretty much.

“We wanted it to be influenced by Chicago, Detroit and all that stuff. But it’s a city that was born from the album pretty much. Those businesses and places and characters will all be coming a life. And we’ll keep on putting them in different situations, as we progress through this triple album we’re about to go through

Before Shit Got Weird features JID, Chance The Rapper, 6LACK, Guapdad 4000, KEY! and A-Track, among others. Check it out below.

our missionCool Crypto Kids was created to provide financial solutions for costly medical care and treatment. Rising healthcare costs have very real consequences for families and their quality of life. The price of medical care is the single biggest factor behind U. healthcare costs, which account for 90% of healthcare spending. Understandably, low-income families and individuals are much more affected, because caring for those with chronic or long-term medical conditions and the increased cost of new medicines, procedures, and technologies can be overwhelming. Cool Crypto Kids is committed to facilitating financial relief solutions for individuals, their families, and their loved ones affected by a healthcare crisis.

• If you set up a wallet through Rarible, you’ll be able to find your NFT in your Rarible wallet viewable on your Rarible “profile” page. If you set up a separate wallet, such as Metamask, your NFT will be automatically added to your wallet upon purchase. Then, go to an aggregator site such as Rarible or OpenSea and log in using your wallet to view your NFTs!
• It does not! Ethereum, like traditional currency, is a fungible asset. This means that one Ethereum token always equals that of another Ethereum token. So while the crypto markets are more volatile than most, if you buy 1 ETH, even if the price of Ethereum goes up or down, you will still have 1 ETH. So feel free to buy Ethereum in advance if you’d like to speed up your purchase once this drop goes live, and make sure to buy a bit extra to cover gas fees. But remember that fluctuations in the values of Ethereum or Rari Tokens will not affect your purchase in any way!
• Some NFT marketplaces are environmentally friendly, like Tezos. Tezos uses less onerous “proof of stake” algorithms as opposed to “proof of work” algorithms like Bitcoin and Ethereum, and thus consumes much less energy overall.

While increasing self-esteem, confidence, and self-awareness through art, we hope to inspire a proactive community of creators, influencers, and brand partners to champion the support of families in need; to offset the costs of medical treatments that would otherwise bankrupt them.

Testing testing testing — MoonKids

With a basic understanding of how NFTs worked, I started to build out my own project on the Rinkeby testnet — MoonKids.

I knew I wanted to create a generative pixel project, but I didn’t have the time to really pixel a lot of graphics, so I headed over to this awesome dollmaker and created a ton of test images.

With the addition of a few layers: pets, planets, balloons, and backgrounds, I had all the graphical assets I needed. Time for the scary bit — solidity.

Honestly, I have lost count of the number of MoonKids test contracts I wrote. It took me a long time to finally nail down the logic behind Opensea showing the image from the metadata on their website.

I told you I was a solidity noob 🙂

Finally, I got everything working, and I even managed to figure out how to mask metadata pre-minting, so people can’t data hunt for the rarest tokens.

Time to hit the mainnet

I was feeling confident that I could now build a solid solidity contract, so I convinced Lynq (took all of 5 seconds) to help me out, hired some pixel artists, and began work on Faticorns.

The early days were mostly trying to figure out our character design and building our character layering system with PHP. This was the easy part as both Lynq and I have a combined 30+ years PHP experience. Yes, we are older than you might think 🙂

The artwork was an evolving process, but we finally settled on the above card format. The example is missing the randomized name and #id.

I put together a contract and we launched, selling to a single person — the awesome Shamdoo. Sadly, we had not perfected our system, and he felt the gas too high. We immediately stopped the sale and went back to the drawing board. And yes we fully refunded him, gas and all.

Optimizing solidity contracts

I actually love optimizing code (total geek right here). I have spent many countless hours battling code versions against each other trying to shave off milliseconds and CPU usage, but optimizing solidity felt like a completely different beast.

Trimming gwei for cheaper minting

To start off, I was writing small changes to my contracts and then deploying them to Rinkeby via remix. I would then run a transaction and compare the gas.

Epic noob right here 😛

Obviously, this methodology was slow and just insane. I knew there had to be a better way — back to Google and StackOverflow.

I eventually found this article about hardhat and these articles about optimizing solidity contracts:

Finally, I had some solid info to work with, and we were off to the races.

Local variables

A lot of NFT contracts seem to borrow code without fully understanding what it does or even bothering to correct mistakes or optimize it. A very common issue (if you can call it that) is the unnecessary use of the totalSupply() function.

This could be written like so:

This simple change reduced gas significantly, but wait there’s more!

Conditionals

Everyone knows how to use conditions, but when do we really think about what is actually happening?

Have a look at this line:

require(num > 0 && num <= 20, «You can adopt minimum 1, maximum 20»);

Clear in its functionality, but in reality, it’s doing too much.

require(num <= 20, «You can adopt maximum 20»);

This less than or equal to is actually doing two things and both cost gas:

But if you simply change the 20 for 21 you no longer need to compare for equals and your line of code becomes.

require(num < 21, «You can adopt maximum 20»);

I told you we got a little obsessed with reducing gas.

Ordering if blocks

This is a massive topic, I’m just going to cover a few very simple bits I learned.

There is no number <0 in solidity and no floating points either. If your maths creates either, expect crashes and transaction failures.

Knowing that most people use a library called safeMaths. sol.

My only issue with safeMaths is its overuse. You don’t have to use safeMaths to do (please correct me if I’m wrong):

uint256 value = 100 / 2;

Using safeMaths for this just adds extra gas costs.

However, please do your own research as I am clearly no expert.

Metadata server

You have probably seen numerous NFTs with blind minting. People mint their tokens and at some point in the future, they are revealed.

Blind minting can be a cool feature, but Cool Cats show their rarity via their backgrounds:

Random screenshot of cats from opensea

I played with a few different methods and eventually settled on a surprisingly simple solution (sharing the test version, not the final).

I simply listen for transactions using web3 and check if the file exists in a sold_tokens directory. If it’s missing, just copy the relevant file into place.

This code also runs on a 5 min timer to catch any that web3 might miss.

Simple and no complicated moving parts to go wrong.

Character builder

This simply uses good old PHP to layer the asset images on top of each other to create the desired end product:

What’s next?

We have big plans for Cool Cats, one of which is breeding on a future contract and generation 2. How this will work is still being discussed with the community.

For now, we are focusing on building the Cool Cats universe. A town or city where they all live together. A simple way to root the community and bind them together to create a feeling of belonging and ownership.

Part of that ownership might even include a way to rename your cats. More on that in a separate post.

All that being said, we take our orders from the community. If the community decides against anything, we scrap it.

Last Word

I feel silly saying this, but I have had so many messages I feel it might save you and me some time.

I have a full-time job IRL and coupled with Cool Cats I am swamped with work, so sadly I have to decline every job offer.

But I am always willing to help out by sharing resources and advice where I can.
