Digital Money Rails are the underlying technological infrastructure and systems that facilitate the transfer and settlement of digital funds. These rails enable the movement of value, encompassing traditional electronic payment networks, blockchain protocols, and emerging distributed ledger technologies. They define the rules, standards, and mechanisms through which digital transactions are processed, from initiation to final settlement. Modernizing these rails seeks to enhance speed, reduce costs, and improve accessibility for all participants.
