Keyrock provides liquidity solutions for digital asset markets by using algorithmic trading and market making on both centralized and decentralized exchanges. Its tech places buy and sell orders automatically to tighten spreads and improve market liquidity, serving B2B clients such as crypto exchanges and blockchain projects. The system works by running proprietary algorithms that continuously quote prices and trade sizes, aiming to offer the best prices while minimizing market impact. Keyrock differentiates itself by operating across multiple venue types (CEXs and DEXs) and focusing on liquidity provision for its clients rather than just executing trades for themselves, enabling partners to run more efficient, better-funded markets. The company’s goal is to enable more liquid and efficient digital asset markets and to generate revenue by charging fees based on trading volume or assets under management, reflecting the value it adds to client ecosystems.
