Noxelle ships as layered APNG traits and as flattened GIF tokens. OpenSea wants the GIF bake of those loops. The mint is $0.25. The APNG stack stays in this repo for the studio and any later restack.
Project description
Collection name Noxelle. Symbol NOXL. Category PFPs. The same copy lives in public/metadata/noxelle-description.txt.
Noxelle. A 10,000-piece collection of looping neon-tube PFP GIFs on Robinhood Chain. Each sign is stacked from seven plates — wall, spill, gas, bend, clip, badge, and mote — then flattened onto one 12-frame GIF. Eight bends: sway, kick, wave, hop, point, dip, spin, and split. Argon, neon, krypton, mercury. Clips hold the glass. Spill stains the club wall. Bent tubing, not a filled body. No sticker edge. No egg. Not a shadow puppet. Not a musical note. The dancer stays seated on one envelope. The dance is the bend. One shared clock. Minting at $0.25 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 10,000-token pack with python3 scripts/generate_noxelle.py --all — gifs/, NOXELLE-opensea-drop.csv, and the kit README land in generated/noxelle/.
In OpenSea Studio, create a Drop on Robinhood Chain (chain ID 4663). Set supply to 10,000, set mint to $0.25, paste the project description, and upload the listing kit from public/brand.
Upload every file in generated/noxelle/gifs (1.gif–10000.gif) and generated/noxelle/NOXELLE-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/Noxelle.sol mints token IDs 1–10,000 at 0.0001 ETH (about $0.25; owner can retune the wei amount). Pin generated/noxelle/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.
