The Series E was led by U.K.-based Kingsway Capital with participation from Lakestar, Lightspeed Venture Partners, and Coinbase Ventures.
Neither Kingsway nor Blockchain.com responded to a request for comment from CoinDesk by press time.
In January, the exchange had laid off 28% of its workforce, according to a report.
Last year, Bloomberg reported that Blockchain.com was looking to raise another round at a valuation of $3 billion-$4 billion. However, the exact valuation for the Series E was not confirmed.
