Currencies Module

Overview

The currencies module provides a mixed currencies system, by configuring a native currency which implements BasicCurrencyExtended, and a multi-currency which implements MultiCurrency.

It also provides an adapter, to adapt frame_support::traits::Currency implementations into BasicCurrencyExtended.

The currencies module provides functionality of both MultiCurrencyExtended and BasicCurrencyExtended, via unified interfaces, and all calls would be delegated to the underlying multi-currency and base currency system. A native currency ID could be set by Config::GetNativeCurrencyId, to identify the native currency.

Implementations

The currencies module provides implementations for following traits.

• MultiCurrency - Abstraction over a fungible multi-currency system.
• MultiCurrencyExtended - Extended MultiCurrency with additional helper types and methods, like updating balance by a given signed integer amount.
