Multi-currency FX overview
A reference for the currencies and settlement schemes behind GBP-anchored stablecoin exchange. Every currency routes through GBP, and that's a permanent part of the design.
Currencies and settlement schemes
| Currency | Central bank | RTGS scheme | Notes |
|---|---|---|---|
| GBP | Bank of England | Synchro (Model 1 today) | The only scheme with a live adapter |
| EUR | European Central Bank | TARGET2 | Already in the HouseAccount enum |
| USD | Federal Reserve | Fedwire Funds Service | FedNow is a separate 24/7 rail. We're looking at it alongside Fedwire. |
| HKD | Hong Kong Monetary Authority | CHATS | Already in the HouseAccount enum |
| SGD | Monetary Authority of Singapore | MEPS+ | Uses SWIFT messaging standards |
| AUD | Reserve Bank of Australia | RITS | FSS/NPP may offer a faster route for time-sensitive legs |
Routing everything through GBP
GBP is the hub. A conversion between two other currencies, say EUR to SGD, goes through GBP in two hops. This is how the system is designed to work. We build currency pairs as demand appears, the same way we build chain adapters, so we only publish pages for GBP pairs.
