EDX Markets has applied for a federal trust bank charter, aiming to integrate Wall Street's equity market structure into the crypto space. Backed by Citadel, Fidelity, and Schwab, EDX's proposal seeks to shift crypto's custody and settlement functions into a federally supervised banking framework. This move could redefine crypto infrastructure by moving away from all-in-one exchanges to a modular system that institutions are familiar with. The application to the Office of the Comptroller of the Currency (OCC) highlights a model where EDX Markets handles order matching, while the proposed trust bank manages custody, fiduciary asset management, and settlement functions. This structure aims to improve capital efficiency and reduce operational burdens for institutional participants. If approved, EDX's model could attract significant institutional flow, reshaping the crypto landscape by aligning it more closely with traditional financial markets.
