Why RFQ is Essential in Institutional Crypto Markets
Why RFQ is Essential in Institutional Crypto Markets

RFQ is a well-established mode of trading in traditional capital markets where it has provided the necessary balance between competitive pricing and institutional discretion for decades. As digital asset markets continue their march towards institutionalization, the adoption of RFQ workflows has become essential. With the launch of its RFQ Platform, Talos is broadening the institutional model for sourcing liquidity and managing digital asset execution. The Talos RFQ Platform replaces fragmented OTC trading with centralized, standardized RFQ workflows for efficient block trading of digital assets in both spot and derivatives markets, or as part of larger workflows such as ETF create/redeem transactions. In the future, it will form the engine for an institutional lending and borrowing marketplace.
