Groovy Nation

Musical note PFPs

Marketplace

Launch on OpenSea, Robinhood Chain.

Groovy Nation ships as layered APNG traits and as flattened GIF tokens. OpenSea wants the GIF bake of those loops. The APNG stack stays in this repo for the studio and any later restack.

Project description

Paste this into OpenSea.

Collection name Groovy Nation. Symbol GROOVY. Category PFPs. The same copy lives in public/metadata/groovy-description.txt.

Welcome to Groovy Nation.

An 8,888-piece collection of looping musical-note PFP GIFs on Robinhood Chain. Each citizen is stacked from six layers — venue, note, expression, topper, cable, and riff — then flattened onto one 12-frame GIF. The notehead is the face. A black stem goes up. Flags and beams sit at the top. Stick arms and legs dance on the beat.

Four notes only: quarter, eighth, whole, and beamed. Bold outline, flat fill, cartoon notation. Shades sit on the head. Chains hang on the chin. Riffs float beside the beat. One shared clock.

Minting on Robinhood Chain (chain ID 4663). Gas is ETH.

Listing kit

Logo, featured, banner, collection GIF.

OpenSea wants a square logo, a 3:2 featured image, and a wide 4:1 banner — three different pictures, no type on the marketplace images. The site hero can reuse the taller banner.

  1. 1

    Traits stay layered. The drop is flattened.

    OpenSea does not stack APNG layers for you. Studio is a live compositor. For a Drop you upload finished GIFs plus a CSV. The full 8,888-token pack is already baked in generated/groovy/ — gifs/, GROOVY-opensea-drop.csv, and the kit README.

  2. 2

    Create a Drop on Robinhood Chain

    In OpenSea Studio, create a Drop on Robinhood Chain (chain ID 4663). Set supply to 8,888, paste the project description, and upload the listing kit from public/brand.

  3. 3

    Bulk-upload GIFs + CSV

    Upload every file in generated/groovy/gifs (1.gif–8888.gif) and generated/groovy/GROOVY-opensea-drop.csv. The CSV already uses OpenSea’s required headers (tokenID, name, description, file_name, attributes[Trait]). OpenSea plays GIF, not APNG. Preview the loops, then publish.

  4. 4

    Or deploy the ERC-721 yourself

    contracts/GroovyNation.sol mints token IDs 1–8,888. Pin generated/groovy/json and set the base URI. Import that contract on OpenSea instead of using a Drop if you want a custom mint. Gas is ETH.
