Build a building. Watch it grow.

1. Pick an empty lot. Skyline Row faces the park. Downtown is south of it. Uptown is the rest of the island.
2. Launch your coin. Name, ticker, picture, optional first buy. One approval with batch-signing wallets; other wallets ask twice.
3. The toll burns TICKER. The lot's toll is swapped to $TICKER and burned in the same approval.
4. Watch it build. Your building gains two storeys every time the market cap doubles, live. Up to 60.

The Battery hosts coins that were on pump.fun before the island. They're guests, placed by the city, not for sale. Placement is not a partnership or endorsement. Coins under $4.5K can become haunted after 12 hours of observed quiet. Buildings are never evicted. Nothing here is financial advice, and coins can go to zero.
