The market for derivatives tied to digital assets is growing.

CNBC has learned that the firm is close to announcing that it is the first major U.S. bank to trade over-the-counter. Goldman traded a non-deliverable option with a merchant bank.

The move is seen as a significant step in the development of the markets for institutional investors. According to the firms, Goldman is taking on more risk by acting as a principal in the transactions compared to the exchange-based CME Group.

The increased maturity of the asset class for institutional players like hedge funds can be seen in Goldman's involvement.

This trade is the first step that banks have taken to offer direct, tailored exposure to the market on behalf of their clients.

The options trades are more relevant to the markets than other exchange-based products.
