Risota 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
Collection name Risota. Symbol RISO. Category PFPs. The same copy lives in public/metadata/risota-description.txt.
Risota. An 8,888-piece collection of looping risograph PFP GIFs on Robinhood Chain. Each print is stacked from seven plates — stock, screen, figure, pass, knockout, slug, and mark — then flattened onto one 12-frame GIF. Eight dancers, each its own spot ink: kick, twirl, pop, sway, hop, glide, stomp, and reach. A second plate slides out of register. Halftone hangs on the sheet. Faces knock through as a dark drum. Soy ink on uncoated paper. Fat blots, not outlines. No sticker edge. No egg body. The dancer stays seated on one envelope. One shared clock. Minting on Robinhood Chain (chain ID 4663). Gas is ETH.
Listing kit
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.

OpenSea does not stack APNG layers for you. Studio is a live compositor. For a Drop you upload finished GIFs plus a CSV. Bake the full 8,888-token pack with python3 scripts/generate_risota.py --all — gifs/, RISOTA-opensea-drop.csv, and the kit README land in generated/risota/.
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.
Upload every file in generated/risota/gifs (1.gif–8888.gif) and generated/risota/RISOTA-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.
contracts/Risota.sol mints token IDs 1–8,888. Pin generated/risota/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.
