BlockFills Bankruptcy: $500M Debt and 2,000 Frozen Client Accounts

A major institutional crypto trading firm has joined the list of firms caught in the industry’s latest downturn. Chicago-based BlockFills filed for Chapter 11 bankruptcy on March 15. This move came weeks after uncertainty that began when the platform suddenly froze client withdrawals. The case that is filed in the US Bankruptcy Court for the District of Delaware shows estimated assets of $50 million to $100 million. In addition, court documents also revealed liabilities that could reach $500 million.

The filing marks one of the most significant institutional failures since the earlier wave of crypto lender collapses. BlockFills has positioned itself as a liquidity and lending partner for hedge funds, asset managers, and mining firms. The company said in its 2025 review that it processed more than $61 billion in transaction volume that year. It reportedly served about 2,000 institutional clients across 95 countries.

The firm had already halted deposits and withdrawals on February 11, citing market conditions and liquidity pressures. For many customers, that meant their accounts were locked overnight.

$75M in Losses, a Walked CEO, and 2,000 Clients Who Can’t Get Their Money

Behind the BlockFills bankruptcy filing are several problems that have surfaced over the past month. Industry reports indicated the company has taken about $75 million in losses while trying to secure new funding or find a buyer. At the same time, the firm was facing rising legal pressure. In a statement, BlockFills said,

The BlockFills team has worked diligently to pursue and evaluate all available strategic and financial alternatives and believes initiating a chapter 11 process, with the intention of consummating a consensual restructuring with our clients and creditors, will provide the necessary time and structure to stabilize the business, pursue additional sources of liquidity and recovery, and explore potential strategic transactions.

Investment firm Dominion Capital filed a lawsuit accusing BlockFills of misusing customer assets and refusing to return millions of dollars worth of crypto held on the platform. A US federal judge later issued a temporary restraining order freezing certain Bitcoin (BTC) connected to the dispute while the case proceeds.

Leadership also shifted during the crisis. BlockFills co-founder and CEO Nicholas Hammer stepped down, with Joseph Perry taking over as interim chief executive as the crypto company entered bankruptcy Chapter 11 proceedings.

Outside the courtroom, frustration from customers began appearing online. Google reviews show the company with a 1-star rating, with several complaints referencing frozen balances. One reviewer wrote that they were unable to withdraw $13,000 from their account.

The collapse is drawing comparisons to Celsius, the crypto lender that froze withdrawals and filed for bankruptcy in 2022. But unlike Celsius, which primarily impacted retail users, the BlockFills bankruptcy is centered on institutional clients.

The freeze has effectively left BlockFills client funds frozen. This is while the restructuring process moves through the court. For the overall market, the episode adds another entry to the list of institutional failures shaping the crypto lender collapse in 2026.
