One of crypto’s longest-running firms is preparing a major public debut with a substantial initial public offering (IPO).

Blockchain.com Group Holdings Inc. is telling prospective investors it wants to go public this year, Bloomberg reports.

The company is seeking to raise about $500 million in an initial public offering, according to people familiar with the matter. Blockchain.com is targeting a $4 billion to $6 billion valuation in the listing and would consider a smaller raise if needed.

Talks are ongoing and subject to change. The plans remain non-public and are based on discussions with potential investors.

Blockchain.com declined to comment on the matter.

Founded in 2011 by three members of the first Bitcoin ( BTC ) online forum, BitcoinTalk.org, Blockchain.com operates as an exchange and wallet provider.

The move comes as the crypto market begins to rebound after a prolonged downturn.

Blockchain.com has operated in the green for the past three years, according to the unnamed sources.
