BlockFills, operated by Reliz Technology Group Holdings, was a Chicago-based institutional digital asset trading and technology firm founded in 2018, offering crypto spot and derivatives trading, liquidity aggregation, lending and SaaS trading infrastructure to hedge funds, brokers, exchanges and miners. After roughly $75M in lending losses and a February 2026 withdrawal freeze, it filed for Chapter 11 in Delaware in March 2026. Keyrock acquired substantially all of its trading and brokerage assets for $3.25M in a court-approved sale completed in July 2026.
