Keyrock has successfully acquired BlockFills' institutional trading and brokerage business, enhancing its trading technology and client relationships. The acquisition includes BlockFills' experienced derivatives trading team and expands Keyrock's regulatory presence with a CIMA-registered entity in the Cayman Islands. Keyrock also plans to seek FCA authorization in the UK. While the acquisition price was not disclosed in the announcement, previous reports indicate a $3.25 million deal during BlockFills' bankruptcy reorganization. BlockFills, based in Chicago, filed for bankruptcy in early 2026 following substantial losses from the February crypto market crash.
