Coinbase Inc., a company that runs a digital currency wallet service and processes payments in bitcoin for merchants, is seeking to raise $100 million in a round of fundraising, The Wall Street Journal reported, citing "people familiar with the matter."

The company recently partnered with Fidelity Investments, which plans to use the Coinbase platform to let clients see their holdings of bitcoin and other digital currencies.

Coinbase has thus far raised about $116.5 million from investors, including Andreessen Horowitz and Union Square Ventures LLC, according to the report. USAA Bank and BBVA Ventures have also contributed to earlier rounds.
