Setheum Tokenization Protocol 258

Multi-Currency Stablecoin SERP Module

Overview

The stp258 module provides a mixed stablecoin system, by configuring a native currency which implements ExtendedBasicCurrency, and a multi-currency which implements SettCurrency.

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

The stp258 module provides functionality of both ExtendedSettCurrency and ExtendedBasicCurrency, 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 stp258 module provides implementations for following traits.

• SettCurrency - Abstraction over a fungible multi-currency stablecoin system.
• ExtendedSettCurrency - Extended SettCurrency wih additional helper types and methods, like updating balance by a given signed integer amount.

Interface
