How the exchange works
Market
List your gold or items at the Exchange clerk in the Lumbridge courtyard, at a dollar price. A buyer clicks buy on this site or in game and pays from their dollar balance; the goods are collected at the Exchange clerk and the seller's balance grows by the price minus a 1% fee. Dollars come in and out as USDT on BNB Chain; the whole of it is on the money page.
Updated 3 October: the exchange is now the Market, the Exchange clerk stands in Varrock West Bank on both worlds, and you buy, sell and bid in the game window; how the Market works.
