BlockFills Files for Chapter 11 Bankruptcy

The BlockFills bankruptcy filing on March 15, 2026 caps what has been a very public, very painful unraveling for one of crypto's more prominent institutional trading desks. Reliz Ltd. — the operating entity behind Chicago-based BlockFills — along with three affiliated companies, filed voluntary Chapter 11 restructuring petitions in the U.S. Bankruptcy Court for the District of Delaware, court records show. The numbers in the filing are blunt: assets somewhere between $50 million and $100 million, liabilities running from $100 million to $500 million. That's a hole that doesn't fill easily.

A Slow-Motion Collapse That Nobody Could Miss

The warning signs had been piling up since at least February. BlockFills froze customer withdrawals and deposits on February 11, citing "recent market and financial conditions" — the kind of vague language that, in crypto, rarely precedes good news. The firm said it was working with investors and clients to restore liquidity. It didn't.

Then came the court filings. A U.S. federal judge handed down a temporary restraining order against BlockFills just days before the bankruptcy, in a lawsuit filed by Dominion Capital. Dominion's allegations were specific and serious: misappropriation of customer crypto assets, commingling of client funds, and deliberate concealment of significant losses. Not exactly minor accounting oversights.

Somewhere in the middle of all this, co-founder and CEO Nicholas Hammer stepped down. Joseph Perry took over as interim CEO — a classic crisis-management move that signals the old guard is gone and the lawyers are running things now.

What Does the Chapter 11 Filing Actually Mean?

What is BlockFills filing for bankruptcy?

Chapter 11 bankruptcy is a court-supervised restructuring process that allows a company to continue operating while it negotiates with creditors and reorganizes its debts. Unlike Chapter 7 — which is a straight liquidation — Chapter 11 gives BlockFills room to potentially sell the business, reduce liabilities, or find new financing, all under judicial oversight.

BlockFills framed the decision as stakeholder-friendly in its official statement. "After extensive discussions with investors, clients, creditors, and other stakeholders, BlockFills has determined that a voluntary chapter 11 filing is the most responsible path forward in order to preserve the value of the business and maximize recoveries for stakeholders," the firm said in a statement. "This filing will allow the firm to implement an orderly restructuring while maintaining transparency and oversight through the court-supervised process."

Call it what you want. The gap between $50–100 million in assets and $100–500 million in liabilities is not an orderly restructuring problem — it's a fundamental insolvency situation. The Chapter 11 language is careful. The math is not.

After extensive discussions with investors, clients, creditors, and other stakeholders, BlockFills has determined that a voluntary chapter 11 filing is the most responsible path forward in order to preserve the value of the business and maximize recoveries for stakeholders.

The $60 Billion Number That Means Nothing Now

Here's the part that stings. BlockFills claimed it processed more than $60 billion in trading volume in 2025, up 28% from the prior year. It serves roughly 2,000 institutional clients — hedge funds, asset managers, mining firms. The platform offered crypto lending, derivatives trading, and OTC execution for serious players.

The BlockFills official statement on the filing mentions that the firm's backers included Susquehanna Private Equity Investments, CME Ventures, Simplex Ventures, C6E, and Nexo Inc. — a roster of institutional names that makes the collapse harder to explain away as some fly-by-night operation. These were serious investors in a firm that processed serious volume.

Yet volume doesn't pay bills when you've reportedly lost around $75 million and a creditor is in federal court accusing you of hiding the damage. Trading volume is a top-line metric that flatters. What happened below the surface at BlockFills is what the bankruptcy proceedings will have to sort out.

What Happens Next for BlockFills Clients?

For the approximately 2,000 institutional clients who used BlockFills for liquidity, financing, and risk management, the Chapter 11 filing creates immediate uncertainty. Chapter 11 does not mean assets are immediately distributed — it means a process begins. That process can take months or years, and recoveries for creditors depend entirely on what the restructuring uncovers.

The Dominion Capital lawsuit — alleging commingled funds and concealed losses — raises a harder question: if client assets were mixed with firm assets, tracing and recovering them becomes a legal battle, not just an accounting exercise. That's the scenario institutional clients are hoping to avoid.

BlockFills insisted withdrawals remain a priority. But "priority" inside a Chapter 11 proceeding is a legal status, not a promise.
