I studied the #ChecksVV smart contract and here's what I found out regarding the elusive Black Check

(Spoiler alert: I’ll show you what it will look like)

🧵👇

There's a dedicated function called “infinity” that the web app will call

64, single checks (divisorIndex must be 6) are required

The first check sent through will remain, with it’s Day set

All 63 others will be burned

No surprises thus far…

You will notice a quote at the end of the function though

It’s from Abdu’l-Baha, who was head of the Bábí Faith, and made after he was released from a lifetime of imprisonment

Just like everything with this project, there’s deep thinking everywhere

The metadata & artwork for Checks is 100% on-chain

NFT contracts have a function called tokenURI that is called to get this info

In the ChecksMetadata library class, you can see the JSON data that is generated

And ChecksArt.generateSVG() is where the magic happens

Normally a single check will look like this

@Schmrypto #1 Check in all its glory

@schmrypto However, in collectRenderData() which is subsequently called…

We can see specific code for the Black Check (data.isBlack)

It changes the gridColor and the canvasColor, giving us this

@schmrypto Then in colors(), we can see that “A fully composited check has no color”

Hence, it is set to ’000’ - solid black

And a question a lot of people have asked:

Will the Black Check animate?

(7/10)

@schmrypto Well, we can see generateChecks() that the fillAnimation() is NOT called for a Black Check

So no animation folks!

And now for the reveal, look away now if you want to keep it a surprise....

@schmrypto Here’s what the Black Check will look like

This artwork will be notable.

@schmrypto Will we ever see it minted?

Will you join the Black Check DAO if it goes ahead?

Let me know in the comments!
