The Ethereum City Citizen’s Handbook: From Claiming Your House to Forecasting Tomorrow’s Weather

How to join a district with zero personal data, upgrade your home from a cottage to a castle, and read the morning paper

Ethereum City is more than a passive 3D dashboard—it is a living community you can join in ten seconds without connecting a crypto wallet or handing over an email address. Here is how to make the most of citizen life, the daily Weather Forecast Game, and the Library.

1. Zero-Personal-Data Citizenship and Picking Your Home District

Click the 🪪 Citizens button in the top bar, choose a nickname (2–16 characters) and any of the 39 districts, and your house immediately appears on the 3D map. Keep your generated Citizen Passcode safe—it lets you bring your house and progress to any browser or phone without an email login.

2. The Daily Weather Forecast Game: Earning Bricks from Cottage to Castle

Every day before the round closes, open Weather → 🔮 Forecast to predict whether tomorrow’s 24-hour market weather (measured at 00:00 UTC / 09:00 KST) will bring Sun (☀️ up), Clouds (⛅ flat), or Rain (🌧 down).

Accurate forecasts award bricks and points that automatically upgrade your 3D house on the map—growing from a Cottage to a Brick House, Two-Story Home, Tower, and Castle (bricks and points are purely non-monetary badges of honor inside the city).

3. 3D Roadside Billboards and the Daily Morning Newspaper

Citizens can spend bricks to submit a short 24-hour greeting to the city’s 3D roadside billboards (reviewed to keep out ads, links, and financial promotions), and every morning after 00:00 UTC a fresh edition of the Ethereum City Morning Paper summarizes the previous day’s weather, gas, movers, and forecast hit rates.

4. Exploring the Library: 39 District Guides, 50 Glossary Terms, and In-Depth Essays

Whenever a building, vehicle, or term catches your eye, open the 📚 Library to browse full written guides for all 39 districts, a 50-term plain-language glossary, the city reading guide, and all in-depth essays.
