Big news from U.S. banking regulators: the Office of the Comptroller just dropped a fresh interpretive letter greenlighting national banks to handle crypto transactions through what's called a "riskless principal" setup. Basically, banks can now step in as intermediaries for digital asset deals, as long as they're playing by the rulebook. This model lets banks facilitate trades without holding the actual crypto risk themselves—pretty significant for institutions wanting to dip their toes into the space while staying compliant.
