Blockfills, a Chicago-based crypto trading firm, has filed for Chapter 11 bankruptcy in the U.S. Bankruptcy Court for the District of Delaware.
The company, which suspended withdrawals in February 2026, reported assets between $50M and $100M against liabilities of $100M to $500M. It cited $75 million in losses and a lawsuit from creditor Dominion Capital alleging misuse of client funds.
A U.S. federal judge issued a temporary restraining order freezing Blockfills’ assets. The firm serves about 2,000 institutional clients, including hedge funds and mining companies, and processed over $60 billion in trading volume in 2025.
Co-founder and CEO Nicholas Hammer stepped down in February. Joseph Perry now leads as interim CEO.
