Fhenix, an Ethereum Layer 2 network developer focused on data confidentiality, has raised $15 million in a Series A funding round.

Hack VC led the round, with Dao5, Amber Group, Primitive Ventures, GSR, Collider Ventures and Stake Capital participating, Fhenix said Tuesday. The firm began raising for the round in March and closed it last month, co-founder and CEO Guy Itzhaki told The Block. He declined to comment on the structure of the round, valuation and board seat offerings if any.

The Series A round brings Fhenix's total funding to $22 million. Last September, the startup raised $7 million in a seed round from Multicoin Capital and others. Itzhaki said there was inbound interest from investors in Fhenix, so it raised the Series A round.
