SOVEREIGN MARKETS / LOCAL LAYERS
Countries are
the base layer.
Cities are markets.
Launch city tokens on top of country tokens. One national base, many local economies — linked through one onchain registry.
THE THESIS
A world of
nested markets.
A country token establishes the root economy. City tokens become local markets beneath it — independently launched, visibly linked, globally discoverable.
Every city has a parent. Every market has a place.
