The U.S. Office of the Comptroller of the Currency (OCC) has granted conditional approvals for five digital asset firms — Ripple, Circle, Fidelity Digital Assets, BitGo, and Paxos — to become federally chartered national trust banks, marking a major milestone in the integration of cryptocurrency into traditional finance.

The approvals, announced Friday, allow the firms to convert from state-level trust charters to federal status, subject to meeting the OCC’s conditions.
