Keyrock Acquires BlockFills Trading Assets to Expand Institutional Crypto Business

Keyrock has completed the acquisition of the trading and brokerage assets of BlockFills’ institutional digital asset business, expanding its capabilities in institutional cryptocurrency trading as demand for professional digital asset services continues to grow.

Announced on Thursday, the transaction adds BlockFills’ institutional client relationships, trading technology, operational systems and derivatives expertise to Keyrock’s existing platform. The Brussels-based company said the acquisition will strengthen its services across market making, over-the-counter (OTC) trading, options, credit, onchain solutions and asset management while expanding its global regulatory footprint.

The deal comes as institutional participation in crypto markets continues to increase, with banks, hedge funds, asset managers and proprietary trading firms seeking regulated partners that can provide liquidity, sophisticated execution and risk management across digital assets. By integrating BlockFills’ institutional business, Keyrock aims to strengthen one of its fastest-growing divisions while expanding its presence in key international markets.

Expanding Institutional Services

The acquisition brings a range of institutional trading capabilities into Keyrock’s business, including proprietary trading technology, brokerage operations and specialized expertise in crypto derivatives.

According to the company, institutional clients will benefit from enhanced execution services supported by Keyrock’s balance sheet, regulatory infrastructure and existing trading framework. Rather than migrating operations immediately, the company plans to integrate the acquired business in phases while communicating directly with affected clients throughout the process.

Juan David Mendieta, Keyrock’s co-founder and chief strategy officer, described the acquisition as an opportunity to accelerate the company’s long-term growth strategy.

“This acquisition represents an exceptional opportunity to further strengthen our team with outstanding talent and accelerate our global reach,” Mendieta said in the company’s announcement.

The deal also significantly strengthens Keyrock’s derivatives business, which has become one of the company’s fastest-growing areas as institutional demand for options and other advanced trading products continues to rise.

Regulatory Footprint Grows

Beyond expanding its trading capabilities, the acquisition also increases Keyrock’s regulatory reach across multiple jurisdictions.

The transaction includes a Cayman Islands entity registered with the Cayman Islands Monetary Authority (CIMA), allowing Keyrock to broaden its global institutional operations. The company is also proposing to acquire a BlockFills entity authorized by the United Kingdom’s Financial Conduct Authority (FCA), although that portion of the transaction remains subject to regulatory approval.

The broader regulatory footprint complements Keyrock’s existing compliance infrastructure and provides additional flexibility for serving institutional clients operating across different markets.

The acquisition also brings several experienced executives and trading professionals into the company.

Among them is Perry Parker, who previously led institutional options at BlockFills after more than 30 years in derivatives markets, including senior roles at Goldman Sachs and Deutsche Bank. Dan Schak, who oversaw risk and trading operations at BlockFills, will also join Keyrock, bringing nearly two decades of experience in options trading, institutional trading systems and risk management.

Additional employees across trading, operations and commercial teams are expected to transition to Keyrock as part of the integration.

Antoine Lours, Keyrock’s head of options trading, said digital asset derivatives have become one of the firm’s fastest-growing businesses, reflecting continued institutional demand for crypto options and related products.

Acquisition Follows BlockFills Bankruptcy

The acquisition follows BlockFills’ Chapter 11 bankruptcy filing earlier this year.

Court documents showed the Chicago-based institutional crypto trading and lending firm reported between $100 million and $500 million in liabilities, compared with assets estimated at between $50 million and $100 million.

CoinDesk previously reported that Keyrock agreed to purchase substantially all of BlockFills’ assets for approximately $3.25 million. The agreement includes selected liabilities, customer relationships, proprietary technology, intellectual property and certain equity interests.

Before entering bankruptcy, BlockFills served approximately 2,000 institutional clients and said it processed more than $60 billion in trading volume during 2025. Its business focused on institutional liquidity, financing, OTC execution and derivatives trading.

The acquisition enables Keyrock to preserve valuable components of BlockFills’ institutional platform while expanding its own capabilities without building comparable infrastructure from scratch.

Institutional Crypto Competition Intensifies

The transaction reflects a broader trend of consolidation across the institutional digital asset industry as firms compete to build larger, more comprehensive trading platforms.

Institutional investors are increasingly looking beyond spot cryptocurrency trading toward derivatives, options and other sophisticated financial products that require robust technology, liquidity and regulatory oversight. Service providers that can combine these capabilities with global compliance frameworks are expected to play a larger role as traditional finance continues expanding into digital assets.

Founded in Brussels, Keyrock has grown into one of Europe’s leading digital asset market makers and institutional service providers, employing more than 220 people worldwide. By combining BlockFills’ technology, client base and experienced trading professionals with its own capital markets infrastructure, the company is positioning itself to compete more aggressively in the expanding institutional crypto sector.

As digital asset adoption among professional investors continues to accelerate, acquisitions such as this one illustrate how established firms are using strategic transactions to strengthen their market position, broaden regulatory coverage and meet growing institutional demand for advanced crypto trading services.
