Keyrock completes acquisition of BlockFills’ trading operations for $3.25 million
The Brussels-based market maker scooped up a Chicago trading firm's assets out of bankruptcy court, paying pennies on the dollar for an institutional client base and proprietary tech stack.
Keyrock, the Brussels-headquartered digital asset market maker, has completed the acquisition of BlockFills’ institutional trading and brokerage operations. The deal, valued at $3.25 million, hands Keyrock the customer lists, proprietary technology, intellectual property, and selective liabilities of a firm that once commanded significant presence in crypto’s institutional trading corridor.
For context, BlockFills listed liabilities between $100 million and $500 million before its collapse. Keyrock picked up the pieces for roughly the price of a nice Manhattan apartment.
From Chapter 11 to new ownership
BlockFills, a Chicago-based trading and lending firm, filed for Chapter 11 bankruptcy on March 15, 2026. The company had reported approximately $75 million in losses, with assets estimated between $50 million and $100 million set against that massive liability range.
The bankruptcy process moved relatively quickly by court standards. Keyrock was named the successful bidder on May 26, 2026, and the US bankruptcy court formally approved the sale on June 16, 2026.
Keyrock itself has been operational since 2017 and carries a valuation of $1.1 billion from its prior Series C funding round.
The consolidation playbook in action
BlockFills served hedge funds, asset managers, and other institutional players who needed reliable execution and brokerage services in digital assets.
There’s a cautionary element here worth noting. Final regulatory clearances for the transaction were still pending as of mid-July 2026. In crypto’s current regulatory environment, particularly in the US, that’s not a trivial detail. Regulatory approval processes can introduce delays, conditions, or in rare cases, complications that alter deal terms.
