Virello

Wind-up tin PFPs

Marketplace

Launch on OpenSea, Robinhood Chain.

Virello 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

Paste this into OpenSea.

Collection name Virello. Symbol VIRL. Category PFPs. The same copy lives in public/metadata/virello-description.txt.

Virello.

A 10,000-piece collection of looping wind-up tin-toy PFP GIFs on Robinhood Chain. Each toy is stacked from seven plates — bench, chassis, enamel, decal, key, spark, and wear — then flattened onto one 12-frame GIF. Eight chassis: robot, duck, racer, soldier, monkey, tank, copter, and frog. The print is lithographed. The key is the loop.

Stamped metal on a toy-shop bench, not a snow globe. Not neon tubing. No sticker edge. No egg. Not a shadow puppet. Not a fold. The toy stays seated on one envelope. The wind-up is the key. One shared clock.

Minting at $0.25 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. Bake the full 10,000-token pack with python scripts/generate_virello.py --all — gifs/, VIRELLO-opensea-drop.csv, and the kit README land in generated/virello/.

  2. 2

    Create a Drop on Robinhood Chain

    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.

  3. 3

    Bulk-upload GIFs + CSV

    Upload every file in generated/virello/gifs (1.gif–10000.gif) and generated/virello/VIRELLO-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/Virello.sol mints token IDs 1–10,000 at 0.0001 ETH (about $0.25; owner can retune the wei amount). Pin generated/virello/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.
