Just a few months ago, BlockFills was still processing billions of dollars in crypto trades for hedge funds and large investors. On the surface, it looked like business as usual. But behind the scenes, financial pressure was building. Now, the Chicago-based crypto trading and lending firm has turned to the courts for protection.
BlockFills, through its parent entity Reliz Ltd. and affiliated companies, has filed for Chapter 11 bankruptcy in the U.S. Bankruptcy Court for the District of Delaware. The filing came after the company halted customer withdrawals earlier this year, citing difficult market conditions and liquidity challenges.

Why BlockFills Filed for Chapter 11 Bankruptcy
Court documents show that the firm listed assets between $50 million and $100 million, while liabilities were estimated between $100 million and $500 million. That gap highlights how severe the financial strain had become.
Earlier reports revealed that BlockFills had suffered around $75 million in losses. The company had been searching for emergency funding or a potential buyer in an effort to stabilize operations. Those efforts, however, did not produce a deal strong enough to avoid bankruptcy.
In a statement, the company said, “BlockFills appreciates the patience and cooperation that clients, creditors, and investors have demonstrated throughout this process.”
Legal Pressure and Allegations
The bankruptcy move also follows a lawsuit filed by Dominion Capital. A U.S. federal judge recently issued a temporary restraining order against BlockFills in connection with the case. The lawsuit alleges that the firm misappropriated customer crypto assets, mixed client funds, and failed to properly disclose significant losses.
These allegations are still being addressed in court, but they added more pressure at a time when the company was already dealing with liquidity problems. BlockFills has not publicly admitted to the claims, and the legal process is ongoing.
A Major Institutional Crypto Player
Before its troubles, BlockFills positioned itself as a key liquidity provider in the institutional crypto market. The firm offered over-the-counter trading, lending and borrowing services, derivatives, and risk management tools for hedge funds, asset managers, market makers, and mining companies.
In 2025, the company reported processing more than $60 billion in trading volume, up 28% from the previous year. It served roughly 2,000 institutional clients and counted investors such as Susquehanna Private Equity Investments, CME Ventures, Simplex Ventures, C6E, and Nexo Inc. among its backers.
Leadership changes followed the crisis. Co-founder and CEO Nicholas Hammer stepped down, and Joseph Perry took over as interim CEO during the restructuring process.
What This Means for the Institutional Crypto Market
BlockFills’ bankruptcy adds to a growing list of crypto firms that have struggled under market volatility. When prices swing sharply and liquidity tightens, trading firms can face rapid losses, counterparty risk, and funding gaps. Even companies serving large institutional clients are not immune.
For customers, the focus now shifts to how much can be recovered through the bankruptcy proceedings. For the broader industry, the case reinforces the need for stronger risk management and transparency, especially among firms that handle large pools of client assets.
Crypto has matured in many ways, but events like this show that parts of the industry are still vulnerable. The coming months will determine whether BlockFills can successfully reorganize or whether its operations will be wound down entirely.
For now, its collapse stands as another reminder that in crypto markets, rapid growth can quickly turn into financial distress. And when trust is shaken, rebuilding it can take far longer than losing it.
