Our take
With crypto demand on the rise, the need for liquidity providers in the securities market is following suit. B2C2 is a digital asset market maker looking to bring best practices into the crypto sector. Beyond providing liquidity, B2C2 looks to shape the future ecosystem in the digital asset realm through crypto-native technology and a dynamic suite of products.
Named the world’s leading crypto market maker, B2C2 has passed several rounds of funding and continues to grow through partnerships and collaborations within the market. For example, it joined forces with Blockdaemon, a blockchain infrastructure company, and Stakewise, a staking protocol, to offer liquidity for staked Ethereum (sETH).
B2C2 has also recently begun working with KX (a database and analytics engine) meaning the company can now deliver real-time data-driven trading insights and decisions to digital assets markets. It’s clear the company is consistently evolving to stay ahead of market trends, once again shown with the securing of regulatory approval to operate in Luxembourg, expanding its footprint in the EU.
