• Set the tokenID in the URL like this: https://render.blonks.xyz/?id=0
• Optional: add &address=<the address to preview> to the URL to preview an address.
• Optional: add &png=true to the URL to render the BLONKS as a png.
• Optional: add &size=<dimension of a side> to the URL to render the BLONKS at a specific size.

BLONKS are 100% on-chain, generative vector-graphic illustrations with no external dependencies. The BLONKS CC0 project is coded in the language of the Ethereum blockchain itself (solidity) and its contracts generate all token data (SVG images and metadata) entirely from data on the blockchain. There is no web-app; there are no hosted files to maintain, update, or accidentally lose. The NFTs will exist as long as the Ethereum network exists, and we all kinda think that's a really really long time.

The project is as pure as what solidity was designed for - financial contracts - yet the resulting BLONKS NFTs are full of life and personality. Other on-chain SVG illustration projects typically utilize either run-line-encoding (pixelated-looking images) or are completely built by combining pre-made assets (head a, with nose b, eyes c, ears d, mouth e, etc.), but BLONKS are different. Entropy (AKA randomness) is taken from the owner's address, details regarding the block that the BLONK was minted in, and from an on-chain pseudo-random hash. From these inputs, over a hundred different generative values are calculated and passed between the various BLONKS smart contracts (a feat in itself). Each component contract pushes the limits of what Ethereum and Solidity can handle, and when working together, the combination of contracts become the BLONKS 'back-end.'

The images created are infinitely-scalable, vector-graphic SVGs. The SVG Retrieval tool above simply retrieves and displays the SVG data that is rendered on the blockchain. Anyone can get the SVG manually by using the 'getSVG' function from the smart contract (function #17 in the 'Read Contract' section on Etherscan). An internet search for 'SVG Code Viewer' will return free browser-based apps to view the SVG code (like this one Matto "made" on a code-sharing site), or you paste the code into a text editor, save it with the extension '.svg', and then open the file in a web browser. The 'previewSVG' function on the smart contract works in a similar way (function #25 in the 'Read Contract' section on Etherscan), but it allows the input of a custom address to show what the NFT would look like if owned by that address.

The address that owns a BLONKS NFT determines the base-image of the BLONK, which includes the starting color palette. There are 5,832,000 possible starting color palettes, and as each SVG is generated, entropy from the owner's address is used to determine how the color components change. There are over 1.6 Nonillion (10^30) different color combinations possible in the base-image of every BLONK, which is more of a fun fact than a useful bit of information. Also, the owner address is used as entropy to determine the shape and positions of different BLONK facial features, like eyes, eyebrows, nose, mole, head height and width, etc. Simply put, BLONKS are super colorful and have an incomprehensible variability even without their token-assigned and locked 'attributes.'

A BLONK's attributes (ex. hair, headband, teeth, etc), are determined by the pseudo-random hash assigned to the NFT at mint. These attributes do not change when the NFT is bought/sold/transferred. These are where 'rarity' comes in, but note these calculations do not consider any aspects or details of the base-image, which changes every transfer. These attributes are applied over the top of the base-image, sometimes continuing the color changes from the BLONK (hair/beard color), and sometimes using pre-determined colors (ex. eyewear). Because BLONKS NFTs have different size heads and necks, some attributes scale with the BLONK to achieve a 'custom fit'. The grandest example of this is with the eyewear; BLONKS have differently sized and positioned heads, eyes, noses, and ears, so every set of eyewear is custom crafted by the code to fit the BLONK.

The code that creates BLONKS is impressive, and I hope that a BLONK NFT's unique look is appreciated. There are 4,444 BLONKS, a number Matto chose based on some simple criteria. First, it had to be in the thousands to support a community. Even if every collector owned 4, there would be over 1000 separate holders. Second, because the collection is extremely variable in visual aspects and can continually change, fewer BLONKS would create a collection that was less overwhelming to browse. Third, because BLONKS are all made of the same type of SVG shape (<rect/>'s), an edition size that consisted of the same digit was desired (1111, 2222, 3333, 4444, 5555, etc). Finally, because BLONKS are all made of rectangles (4-sided shapes), 4444 was chosen.

The 'meme' starting price of 0.0420 Eth was selected for memorability, humor, and affordability. 50% of the mint-proceeds are being transparently donated to charity through an Endaoment Donor Advised Fund (a fund simply named "MonkMatto" and advised by - you guessed it - Matto). These kinds of Endaoment funds allow individuals and groups to donate to multiple organizations, and thanks to the blockchain, everything is transparent. Matto has decided to donate to 4 charities:

• $4500 was sent to The Nature Conservancy. "The mission of The Nature Conservancy is to conserve the lands and waters on which all life depends. Our vision is a world where the diversity of life thrives, and people act to conserve nature for its own sake and its ability to fulfill our needs and enrich our lives."
• $3000 was sent to OutRight Action International. "OutRight is the only global LGBTIQ organization with consultative status and a permanent presence at the United Nations Headquarters, where we advocate for human rights and equality for LGBTIQ people, serve as secretariat of the UN LGBTI Core Group and act as a watchdog on all 193 world governments."
• $3000 was sent to Food Bank Of Central & Eastern North Carolina. "Established in 1980, the food bank is a nonprofit organization that has provided food for people at risk of hunger in 34 counties for over 37 years. The food bank serves a network of more than 800 partner agencies such as soup kitchens, food pantries, shelters, and programs for children and adults…"
• $1000 was sent to Durham Arts Council. "Durham Arts Council is a catalyst in the cultural development of Durham - it leads, inspires, and promotes excellence in and access to the creation, experience and active support of the arts for all the people of our community."

Who got the pre-sale airdrop?

The first 182 BLONKS were airdropped to the first 182 FOCUS collectors. 22 BLONKS were minted to an account Matto controls, to be used for future giveaways, rewards, etc, but none will be used to sell for profit. About 100 were airdropped to Matto's irl fam, irl friends, and internet frens. ~20 were airdropped via a casual giveaway in the Art Blocks discord, and a final 10 via a giveaway in Grailers discord. In total, 333 were airdropped, leaving 4,111 of the 4,444 BLONKS available for public mint.

After public sale opened, Matto minted/is minting additional BLONKS to anyone he feels is worthy of a free BLONKS, but never to any influencers for the sake of their influence (which would be lame and very unBLONKS like).

Roadmap?

The motivation of this project is to create something without any dependencies, and a roadmap is a selling point, which in effect would imply a sort of abstract dependency - something the project is relying on to somehow promote itself. So, to answer that question: nope.

 Roadmap?  Matto's future role?

Main builder for BLONKS stuff, for fun and joy, to share with the world. I likes the BLONKS, so probably going to keep having a blast with them!

Is this a good investment? Will it make me money?

Read the disclaimers / terms below.

I couldn't have created BLONKS without the technical contributions of some lovely people! Here they are:

• Brecht Devos published code for encoding in base64, which is needed for on-chain and in-browser rendering svgs.
• Julien helped me get up to speed with testing in Hardhat, and was a great troubleshooting and brainstorm fren! 🙏
• Tib and outerpockets both took peeks at various contract-control functions, helping me feel more confident.
• Sterling Cripsin gave me a leg up with web3 integration - all the published tutorials out there are unnecessarily complex!
• John Au-Yeung's post on converting an SVG to an image in the browser allowed me to add that function as an option to my url-parameter render tool.
• Immutable Computer helped me get a sales-tweet bot set up and running off a raspberry pi using python! (so much fun!)
• (more coming soon)

And guess who helped me with the amazingly robust backed for BLONKS? The one and only, ETHEREUM blockchain. Thanks for all the hard work!

That's mostly it on the technical side, for now, but there's plenty more that can be built and there'll be many others who will help make BLONKS the amazing project it's destined to be. I'll try to keep this updated, but here's a pre-emptive THANKS! to future contributors.
