# USD → SGD: US Dollar to Singapore Dollar settlement on Sera

> This is the single most-requested corridor on Sera's book. Over the last 30 days takers quoted more than $4M of USD→SGD demand and almost none of it filled, because there is no XSGD inventory sitting on the pair. Singapore is the treasury hub for the region, so dollars land here before they go anywhere else in ASEAN.

- **Corridor:** USD ↔ SGD (United States ↔ Singapore)
- **Status:** Live
- **Bridge stablecoins:** USDC ↔ XSGD
- **Settlement speed:** Sub-second on-chain · ~10s door-to-door
