Treasury Prime Launches OneKey Banking API for Multi-Bank Network
On March 15, 2023, BaaS middleware provider Treasury Prime launched OneKey Banking, a new API designed to unlock the full potential of its multi-bank network comprising more than 15 partner institutions. OneKey enables fintechs and platforms to offer instant cross-bank transfers, deposit growth strategies, risk mitigation, and product partnerships through a single integration. The product addresses a key challenge in BaaS by allowing seamless movement of funds and distribution of deposits across multiple bank partners.
Within its first month, OneKey facilitated over $350 million in deposits across the network, demonstrating strong early traction. The launch positions Treasury Prime to differentiate from single-bank BaaS providers by offering network-level capabilities. For bank partners, OneKey creates new deposit acquisition channels and product diversification opportunities.
The product reflects growing sophistication in BaaS infrastructure as the market matures beyond basic account and payment APIs.
