The financial system works better the closer you are to New York and London.

I said this in a recent interview with Seoul Economic Daily. Between emerging economies, the same payment still takes longer and costs more. That gap is where stablecoins matter most.

When both currencies exist as stablecoins, they can be exchanged directly. The intermediary banks drop out, and businesses save both time and fees.

We talked about Korea too, where card payments already work well. Used only locally, a won stablecoin risks becoming little more than a marketing tool. Its real value is in foreign exchange.

It’s the same lesson we learned early at @CodexFX. Customers wanted to convert the money they held into the currencies they needed, across both fiat and stablecoins.

Once we built around that, volume grew quickly. In August alone, it topped $1B.

Stablecoin FX is only beginning, and the decisions made over the next 5 to 10 years will determine how the financial system works for the next 100.

Thanks to Do Ye-ri for a sharp conversation.

Stablecoins can move a remittance across borders in seconds.

For remittance companies, the challenge is getting from fiat to stablecoins, then back into local currency at the other end.

Money on stablecoin rails moves around the clock. The compliance checks on those payments need to keep the same hours.

We've chosen @FlagrightHQ for real-time transaction monitoring and AML screening on payments through Codex.

[Flagright @FlagrightHQ]

💬 "Codex is committed to delivering seamless stablecoin FX, and with that comes the responsibility to proactively identify and eliminate illicit activity," said Haonan Li, CEO and Co-Founder at Codex. "Flagright's platform provides the advanced analytics and screening we need to monitor every transaction in real time and meet evolving regulatory standards."

@CodexFX, the stablecoin FX platform, has deployed Flagright to strengthen real-time transaction monitoring and AML compliance across its cross-border payments business.

For payment infrastructure built around speed, managing risk cannot become a bottleneck. The right controls need to operate at the same pace as the transactions they protect.

Growing at 55% month-on-month, they're now the place where PSPs and fintechs go when they need to shift $250 million to $500 million in stablecoin FX without losing half a point to some 1990s-era banking hierarchy.
