EDX Markets,customizable crypto paper trading and backtesting tool for grid trading the crypto exchange backed by Citadel Securities, has applied for a national trust bank charter, marking a new step in its push to serve institutional clients.\n\nThe exchange submitted its filing to the Office of the Comptroller of the Currency on Wednesday, according to documents seen by CoinDesk. The move comes about three and a half years after the firm launched .\n\nIf approved, the charter would allow EDX to offer custody, asset management and principal trading services, while continuing to run its core order-matching platform. The filing outlines a structure where custody and settlement sit within a regulated trust entity, separate from trading operations.\n\nEDX Markets targets traditional finance firms entering digital assets. Its backers include Fidelity Digital Assets and Charles Schwab Corp, alongside Citadel Securities. The platform went live in the summer of 2023 with four cryptocurrencies: bitcoin BTC $ 66 277,99 , ether (ETH), LTC $ 51,92 and bitcoin cash (BHC). It has since expanded to include 17 additional tokens.\n\n“EDX Trust is a key step in bringing traditional market structure to digital assets,” CEO Tony Acuña-Rohter told CoinDesk. “By separating custody and settlement into a regulated trust, we’re building the kind of infrastructure banks and institutional investors expect as they scale into the space.”\n\nEDX is not alone in seeking this type of regulatory footing. Several crypto firms have applied for and received trust bank charters in recent years, using them to offer custody and other services under U.S. oversight. These approvals have become a key pathway for firms looking to attract institutional capital.\n\nCompetition for those clients has intensified. Large asset managers and trading firms want platforms that mirror the safeguards and structure of traditional markets. In practice, that can mean segregated custody, clear settlement processes and regulated entities that reduce counterparty risk. For exchanges like EDX, securing a trust charter could help bridge that gap.
