Vera Molnar’s paintings were sold out in just an hour. In total, the artist earned 631 ETH ($ 1.2 million) for them. In addition to geometric shapes such as squares and triangles, Molnar used the letters “N”, “F” and “T” in her works.

For the first time in its 300-year history, Sotheby’s auction house held a sale in the format of a Dutch auction — participants put the highest price at which an item will be sold, and then lower it until the buyer makes a bid. The maximum set price at this auction was 20 ETH ($37,506).
