# Modelling FX swaps in LUSID

You can model an [FX swap contract](https://www.investopedia.com/terms/f/foreign-currency-swaps.asp) as an instrument of type `FxSwap` in LUSID. [See all supported instruments](/v1/docs/what-instruments-does-lusid-support).

## Mastering an instrument

There are [numerous tools](/v1/docs/how-do-i-master-an-instrument) you can use to master an `FxSwap` in the LUSID Security Master.

Some fields are common to all types of instrument, such as an intuitive `name`, the [requirement to specify a set](/v1/docs/understanding-instrument-identifiers) of `identifiers`, and the facility to [store extra information](/v1/docs/properties) as `properties`.

Fields in the economic `definition` object are specific to `FxSwap`. For more information on these fields, select **FxSwap** from the **definition** dropdown in the [UpsertInstruments](https://www.lusid.com/docs/api/lusid/endpoints/instruments/UpsertInstruments) API reference, or alternatively examine the [FxSwap](https://www.lusid.com/docs/api/lusid/schemas/FxSwap/) schema:
