Gold pulses are buys. The teal zone is everything you can't place.
Each buy flies into the price and lights it up. Swaps from other chains into ZEC surface in the shielded zone, because there is no honest place to put them on a map.
Exchange buys
Every buy on Kraken, Coinbase, Gemini, Binance, Bitfinex, OKX, Bybit, Gate and Bitget appears as it happens. Trades paid in a local currency land in that region: EUR in Europe, JPY in Japan, USD across US cities. Trades paid in USDT, USDC or BTC have no real location, so they are scattered across crypto hubs around the world.
Swaps into ZEC
Swaps from other chains into ZEC through NEAR Intents rise out of the zone as teal logos and fly into the price. Only chain and size are used, never addresses. If the live swap feed cannot be reached from your browser, the zone replays recent real swaps and says so in the counter.
Why a hidden zone
Shielded Zcash hides amounts and parties, so there is nothing to place on a map. The zone shows that activity happens, not who or where.
