Birch Hill, a company founded by former Goldman Sachs and BlackRock employees, announced the completion of a $4 million seed funding round led by Multicoin Capital, with participation from ParaFi Capital, Castle Island Ventures, and Nascent, bringing its total funding to $6.5 million. The company plans to build regulated pathways to bring U.S. multifamily, farm, and energy loans onto public blockchains. Birch Hill has applied to FINRA for broker-dealer membership and has met with the SEC's crypto working group, aiming to advance on-chain credit products within existing regulatory frameworks.
