BlockFi was a Jersey City, New Jersey crypto-financial-services company founded in 2017 by Zac Prince and Flori Marquez that offered retail and institutional clients interest-bearing crypto accounts (the BlockFi Interest Account), USD loans collateralized by bitcoin and other digital assets, spot trading, and a bitcoin-rewards credit card, growing on a USD 350 million Series D in March 2021 that valued it at roughly USD 3 billion. The company filed for Chapter 11 bankruptcy protection in November 2022 in the wake of the FTX and Alameda Research collapse, and emerged in October 2023 not as an operating business but as a wind-down estate. Its customer web platform and mobile apps have been shut down, in-kind crypto distributions are administered through Coinbase and cash distributions through Kroll Restructuring Administration and Digital Disbursements, and blockfi.com is now a WordPress notice site carrying noindex/nofollow and dated estate updates rather than a product. There is no operating developer program: api.blockfi.com and every other developer, docs and app subdomain no longer resolve in DNS, the company GitHub organization holds zero public repositories, and no OpenAPI, GraphQL, AsyncAPI, MCP or agent-card document is served from any surviving BlockFi host.
