BirbNation

Round robin PFPs

Marketplace

Launch on OpenSea, Robinhood Chain.

BirbNation ships as layered APNG traits and as flattened GIF tokens. OpenSea wants the GIF bake of those loops — the same path Hoodkins uses. The APNG stack stays in this repo for the studio and any later restack.

Project description

Paste this into OpenSea.

Collection name BirbNation. Symbol BIRB. Category PFPs. The same copy lives in public/metadata/birbs-description.txt.

Welcome to BirbNation.

A 2,222-piece collection of looping painted-robin PFP GIFs on Robinhood Chain. Each birb is stacked from four layers — field, plumage, mug, and accent — then flattened onto one 12-frame GIF. Soft fields behind them. Chocolate caps. Burnt-orange chests. Cream bellies. Hats, crowns, and the occasional worm. Eyes blink. Wings twitch. The body stays a sphere.

Painted 3D illustration — canvas grain, wrap shade, a warm key from the left. Explorers, dreamers, jokers, guardians. One nation. 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. Run the generator to bake each token onto the shared 12-frame clock, then gif_bake.py to make the marketplace loops.

  2. 2

    Create a Drop on Robinhood Chain

    In OpenSea Studio, create a Drop on Robinhood Chain (chain ID 4663). Set supply to 2,222, paste the project description, and upload the listing kit from public/brand.

  3. 3

    Bulk-upload GIFs + CSV

    Upload every file in generated/birbs/gifs (1.gif–2222.gif) and generated/birbs/BIRBS-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/Birbs.sol mints token IDs 1–2,222. Pin generated/birbs/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.
