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.
💬 "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.

Out Now: Read the story of @haonan and @victor_yaw_ , Co-founders of @CodexFX on their bet on building the Stablecoin FX liquidity house that the world will rely on as more assets come onchain.
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.
Now on Out of Pilot.

$1.2B in monthly volume.
A new record that's driven by Codex Par, our most recent product (1:1 swaps between USDT and USDC, with Codex handling the liquidity and fees billed to you separately).
Our "Dollar Machine" thesis has kept proving out: we're the fastest, most accessible way to move between US dollars, local currencies, and dollar stablecoins, anywhere in the world.
Now with Par live, we're also the most seamless way to move between the two biggest dollar stablecoins onchain.
More coming to expand what Codex FX can do as we build toward a complete onchain FX platform for global money flows.
Stay tuned!
