GREENROM is a deterministic, monochromatic NFT ecosystem built around 2048 sealed cartridges on Base. It draws its language from the handhelds of the early 1990s — the four-color green palette, the low-bit silhouettes, the cassette-like cartridge shell — and turns them into a long-form collectible whose meaning is discovered, not announced. It is not a meme drop. It is not a P2E project. It is not a generic procedural PFP collection. GREENROM is an experimental piece of retro-computing: every cartridge carries a 64-bit genome, fixed before mint, that fully determines the organism it contains. Genomes are minted blind. Holders choose if and when to reveal. The community is the discovery layer — the rarity, the species, the lineage of each cartridge become legible only as more cartridges are opened and more genomes are decoded. ## What GREENROM is * **Retro-computational.** Original Game Boy palette only: `#0F380F`, `#306230`, `#8BAC0F`, `#9BBC0F`. No gradients, no shadows, no glossy effects, no card-frame NFT chrome. * **Deterministic.** The same genome always produces the same organism. There is no randomness at render time, no marketplace-side stat re-roll, no admin function that can mutate a cartridge after mint. * **Modular and collectible.** 2048 cartridges, 16 species, 16 head sprites × 16 body sprites, distributed across five rarity tiers — including 16 true Prime 1-of-1 specimens. * **Atmospheric.** Each cartridge is a small, sealed artifact. The unrevealed state is a finished aesthetic in its own right. ## What GREENROM is not * A meme NFT. * A colorful cartoon collection. * A speculative P2E loop. * A card-art PFP project. ## Status — live on Base GREENROM Genesis is **deployed and verified on Base mainnet**, and the public mint is **open**: 2048 sealed cartridges, 0.005 ETH each, 32 per wallet, first-come, first-served. * **New here?** Start with [Mint Status & How to Mint](/getting-started/mint.md). * **Want the full arc?** See the [Roadmap](/getting-started/roadmap.md). * **The only official contract:** `0xf2605352Ab6485886b8142A472F07EF43b284fD7` — verify it on [Basescan](https://basescan.org/address/0xf2605352Ab6485886b8142A472F07EF43b284fD7#code) and against the [Official Links](/help/official-links.md) before you mint or buy. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.greenrom.xyz/introduction/readme.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
