Open USD signals that stablecoins are moving from crypto product to payments infrastructure. That may create real opportunities for faster settlement, cross-border movement, platform payouts, and shared economics, but shared infrastructure still needs governance, reconciliation, compliance, reserve oversight, risk ownership, and adult supervision.

Sponsor banks are not just payment plumbing. They are risk partners, and they do not like discovering late that your merchants, volume, fraud, chargebacks, ACH returns, vendors, or product roadmap have drifted outside the story they approved. If you depend on a sponsor bank, clear communication, real controls, clean reporting, and early escalation are not optional.
