Blueprint Finance has secured a strategic funding round led by Polychain Capital to scale Concrete, its institutional DeFi infrastructure platform. Participants include Bullish, Keyrock, BitGo, FalconX, G-20, Flowdesk, JPEG Trading, Sentient Capital, Andes, and 2Square. The company develops full-stack vault infrastructure enabling institutions and asset managers to launch and manage on-chain capital allocation strategies. Concrete integrates execution, accounting, risk controls, and rebalancing within a unified vault system. Blueprint Finance has expanded its ecosystem with new financial primitives, including AssetCX and concUSD. The round brings together investors spanning venture capital, institutional trading, custody, and liquidity provision. CEO Nic Roberts-Huntley stated the strategic partners operate at the centre of digital asset markets, providing expertise across liquidity, execution, and distribution.

Keyrock has completed the acquisition of BlockFills' digital asset trading and brokerage business for $3.25 million. The Brussels-based market maker gains institutional clients, derivatives expertise, and proprietary technology from BlockFills, which had filed for Chapter 11 bankruptcy protection after significant lending losses. The deal brings two senior traders to Keyrock: Perry Parker, a former Goldman Sachs and Deutsche Bank options specialist, and Dan Schak, who led risk and trading operations. Keyrock also acquires a CIMA-registered entity in the Cayman Islands and a UK FCA-authorised entity, pending regulatory approval. The acquisition follows Keyrock's Series C funding round in March, which valued the company at $1.1 billion, led by Standard Chartered's SC Ventures. The deal strengthens Keyrock's position in crypto derivatives, a growing segment among hedge funds and asset managers seeking sophisticated risk management tools.
