The CHROMA Manifesto

  • The Art (inspiration)
  • The Medium (technology)
  • CHROMA Sources (governance)
  • CHROMA Cache (supply)
  • Cachenomics (implications)
  • Licencing (CC BY-SA 4.0)

Immersion allows the viewer to become one with the artwork.

The Codex prototype, collect-code, TBD, featuring CHROMA-IV#11,


As Smart Contracts are used to drive how Artwork is generated or delivered, now the medium itself becomes part of the Artwork.


  • Choose to Build, and the Smart Contract will generate the final Artwork with its actual pixels, which will be stored on-chain, with the Smart Contract, accessible via the ECR721 standard tokenURI() function.
  • Choose to Source, and the Artwork will not be generated at mint time. Sources can be built anytime later, by the current Token owner only, with some gas. The act of Building is irreversible.
CHROMA Source Tokens

CHROMA Sources are like a mystery box, or a sealed card pack, which contents can only be seen when the seal is broken, by Building it.

The Quadruplets CHROMA-V#38, #39, #40, #41 (Screaming For Immersion)


  • Launch: The Coder (contract owner, The Artist) mints Token #0. This event automatically opens the contract for public minting.
  • Initial Public Offering (IPO): The first 50% of the supply is available to mint freely, Built or as a Source. There is a steep bonding curve, pricing is calculated as (InitialPrice x TokenNumber).
  • Source Reduction: The remaining 50% comprise the Holder’s Cache. The contract will only allow new mints if less than 10% of minted tokens are Sources (Cache Threshold). Sources above the threshold need to be built by owners or sold to collectors willing to build them.
  • Cache Offering: When the Cache Threshold is reached, Source Holders can control the contract's supply. By building one Source, they quickly open a new window for minting a new Source and control supply again.
  • Source Falloff: 100% minted. The remaining Sources could become the most valued tokens, as they give access to the final remaining Artworks of the collection.

Source Holders become the dealers of new mints.

  • Builder Protection. Some guarantee that the Builder will be able to mint a Cached Token after building a Source, like a short time lock, while only the Builder can mint. Or Build and Mint in one single method call.
  • Source Limiters. To purchase a Source, the buyer needs to own at least one Built Token. Or set a maximum Source-to-Built ratio (ex: no more than 20% of minted Tokens can be Source).
  • Source Auctions. A Source is put on auction. Once settled, the Source is automatically built and transferred to the Buyer, allowing Holders to mint their cached token. Builder Protection could mint the new Source to the Seller automatically.
  • Bribe Pools. Bribers can deposit tokens (NFTs, ERC20, ETH...) to the contract in exchange for a newly built token. If any of the current Source Holders accepts a bribe, Source is built and transferred to Briber, and Bribe is transferred to Holder.
  • Dynamic Cache Pricing. Flat prices during IPO, but Cached Tokens prices can rise with the market floor price.
  • Source Building Events. Akin to Card Breaking, popular among sports cards collectors, events could be organized to build and sell Sources, by auction, raffle or guessing of the built Artwork contents.
  • Twisted Cache Parameters. It would be interesting to see what happens if some key parameters that drive the CACHE are changed. Larger supply. Lower Cache Threshold. No bonding curve.
  • Completely new use of Sources. Sources have the potential to become a temporary currency token. Give access to other collections. Used as giveaways. Send to a friend as a wrapped gift!
