6,666 demons.
Three forms.
Let the Devilution begin.

Small pixels. A dark personality.

Cinderkin starts with a fixed 24×24 pixel foundation, exported at 768×768 to preserve those bold, unmistakable pixel shapes. Horns, eyes, colors, clothing, and accessories give the collection its character, while two mutation forms take that identity somewhere new.

Across the collection, there are 19,998 artwork images: an Original, Parasitic Corruption, and Crystal Growth form for each of the 6,666 NFTs.

Those are three visual identities for the same token. Your demon’s appearance can change while its token ID stays with it throughout the journey.

Your holding journey, made visible

Devilution is our twist on evolution. The contract tracks how long your demon has remained in its current wallet and selects its eligible artwork form.

The journey begins with the Original form. After reveal, this is the demon you get to know: its colors, its features, its attitude. Then the holding milestones begin to matter.

Your demon takes on its parasitic mutation artwork. The character remains recognizable, but corruption introduces another side of its identity. You have reached the first milestone—and the journey can keep going.

This is the final form in Cinderkin’s three-stage journey. Crystal Growth gives your demon its second mutation, turning a long holding streak into a visible part of your collection.

Think you have diamond hands? Here is your chance to make them crystal clear.

The timing matters: 666 days is the total continuous holding period, not another 666 days after reaching Devilution 1. Both milestones use consecutive 24-hour days, measured from mint or the most recent transfer.

One NFT. No mutation claim required.

You do not need to mint a second token, burn your original, or pay an additional mint price to reach a Devilution milestone.

The contract determines the eligible form automatically. Your existing NFT displays the corresponding artwork; you do not receive three separate NFTs or independently tradable versions.

OpenSea caches artwork and metadata, so the visible image may need a metadata refresh after a milestone. Eligibility comes from the contract even if the marketplace display takes time to catch up.

Transfers start a new chapter

Selling or transferring a Cinderkin resets its Devilution holding clock.

The demon returns to its Original form once revealed, and its new holding journey begins. That includes transfers between wallets you own. A transaction transferring the NFT back to the same wallet also resets the clock.

Its underlying character and grail status remain intact. What resets is the continuous holding progress toward Parasitic Corruption and Crystal Growth.

For collectors who enjoy following one character over time, that is the heart of Cinderkin: your time with your demon becomes part of how it appears.

Ten grails. Three forms each.

Within the 6,666-piece collection are 10 special grails.

Each has its own Devil Name, distinctive artwork, and both Devilution forms. Their metadata carries a single Devil Name trait, while their visuals still follow the same Original → Parasitic Corruption → Crystal Growth journey.

These ten grails are included within the 6,666 supply. They are not an extra collection or an additional mint allocation.

They also follow the same rules as every other Cinderkin: 66 continuous days for Devilution 1, 666 for Devilution 2, and a reset upon sale or transfer. Even a grail has to earn its crystals.

Six days inside the box

Every newly minted Cinderkin begins behind our animated mystery-box placeholder.

Each NFT reveals six days after its own mint. The collection does not need to sell out first, and a later mint does not share an earlier buyer’s reveal date.

The reveal timer and holding timer are separate. Transferring your NFT restarts its Devilution progress but does not restart the six-day reveal delay. If it is still unrevealed, the mystery box remains until its original reveal time arrives.

The mint

Cinderkin’s mint price is 0.006666 ETH per NFT, plus Ethereum network gas fees, during both presale and public mint.

The mint schedule is:

Presale: December 1, 2026, at 6:06 a.m. EST.

Public mint: December 2, 2026, at 6:06 a.m. EST.

Presale lasts 24 hours. Public mint is planned to stay open until the collection sells out.

Allowlisted wallets can mint up to 3 during presale and up to 9 total across both phases. Unused presale allowance rolls into the public stage. Mint all 3 during presale and you can mint up to 6 more publicly; mint none during presale and your public-stage eligibility can cover up to 9.

Non-allowlisted wallets can mint up to 6 during public mint. Moving NFTs to another wallet does not restore the sending wallet’s mint allowance.

Allowlist applications are open for team review. Final eligibility is determined by the configured sale. Check the official collection page for confirmed sale settings and eligibility before minting.

Artwork locked. Devilution alive.

The Cinderkin contract is already deployed on Ethereum, and its source has been published and verified through Sourcify.

The placeholder and all three artwork/metadata base addresses are permanently frozen. The images and metadata are stored on IPFS, with the contract selecting the appropriate fixed form as your holding period changes.

Freezing those addresses preserves the artwork destinations while allowing the six-day reveal, both Devilutions, and transfer resets to keep working. IPFS hosting still requires maintained pins. The artwork freeze does not freeze sale settings or every administrative control.

The contract also has a 6% creator royalty configured. Marketplace support and enforcement determine how that royalty applies to a secondary sale; it is separate from the primary mint price and network gas.

Choose your demon. See how far you go.

Cinderkin brings together the appeal of expressive pixel art, the excitement of ten special grails, and a clear visual journey for collectors who want to stay with their character.

You can arrive for the artwork. You can set your sights on Parasitic Corruption. Or you can look all the way ahead to day 666 and decide that Crystal Growth is your destination.

The invitation is simple: find a demon you want to keep company with, and let time reveal another side of it.
