# Currencies and Auto Currency Conversion

> StablePay's stablecoin settlement, pricing currencies, product support scope, and auto currency conversion rules.

StablePay enables merchants to price in multiple fiat currencies and complete stablecoin payment acceptance and settlement via USDT or USDC. When merchants price in non-USD currencies, StablePay automatically converts the displayed amount to its USD equivalent during checkout, then completes the payment in stablecoins.

This page consolidates information regarding currency support for Checkout, Payment Links, Subscriptions, and Invoicing, as well as how auto currency conversion applies.

## Settlement Assets

StablePay currently supports the following stablecoins for payment acceptance and settlement:

* USDT
* USDC

## Supported Pricing Currencies

StablePay Checkout and Payment Links currently support the following pricing currencies, utilizing auto currency conversion when priced in non-USD.

| :----------------------- | :--------------------------- |
| Default                  | USD                          |

## Product Support Scope

Not all StablePay products support the same range of pricing currencies.

| Product                  | Supported Pricing Currencies for Goods/Services  | Auto Currency Conversion |
| :----------------------- | :----------------------------------------------- | :----------------------- |
| Stablecoin Checkout      | USD and multi-currencies in the supported list   | Supported                |
| Payment Links            | Same multi-currency range as Stablecoin Checkout | Supported                |
| Invoicing                | USD only                                         | Not applicable           |
| Stablecoin Subscriptions | USD only                                         | Not applicable           |

If your business requires pricing in local currencies such as EUR, JPY, KRW, TWD, or AED, please prioritize using [Stablecoin Checkout](/zh/product/Stablecoin-Checkout) or [Payment Links](/zh/product/Payment-Links).\
If you use [Invoicing](/zh/product/Invoicing) or [Stablecoin Subscriptions](/zh/product/StablePay-Stablecoin-Subscription), you should currently create USD-denominated products or services.

## FX & Settlement Rules

| Item                    | Rule                                                                |
| :---------------------- | :------------------------------------------------------------------ |
| Exchange Rate Reference | Mid-market rates from major international banks                     |
| Additional FX Markup    | No additional markup by default                                     |
| Settlement Asset        | USDT or USDC                                                        |
| Settlement Cycle        | Follows the settlement schedule configured for the merchant account |
| Fee Calculation         | Calculated based on the USD equivalent amount                       |

## Example

If a product is priced at `100 EUR`, Checkout or Payment Links will convert it to a USD equivalent amount based on the current exchange rate. If the equivalent amount is `108.50 USD`, the customer will pay `108.50 USDT` or `108.50 USDC`, and fees are also calculated based on this USD equivalent amount.

## Important Limitations

* Auto currency conversion currently applies primarily to Stablecoin Checkout and Payment Links.
* Invoicing and Stablecoin Subscriptions currently only support creating USD-denominated products or services.
* Payment Links' multi-currency support range is consistent with Stablecoin Checkout.
* Auto FX conversion is enabled by default for supported non-USD pricing currencies.
* If you wish to avoid triggering currency conversion, please set the order currency to USD.
* Supported currencies and specific behaviors may vary by product, account, and integration configuration.
