XRPL Currency Models¶

The XRP Ledger has two kinds of money: XRP, and issued currencies. Both types have high precision, although their formats are different.

class xrpl.models.currencies.IssuedCurrency(*args: List[Any], **kwargs: Dict[str, Any])¶

Bases: BaseModel

Specifies an amount in an issued currency, but without a value field. This format is used for some book order requests.

See https://xrpl.org/currency-formats.html#specifying-currency-amounts

currency: str¶

This field is required.

classmethod from_dict(value: Dict[str, str | int | List[Any] | Dict[str, Any]]) → BM¶

Construct a new BaseModel from a dictionary of parameters.

Parameters:: value – The value to construct the BaseModel from.
Returns:: A new BaseModel object, constructed using the given parameters.
Raises:: XRPLModelException – If the dictionary provided is invalid.

classmethod from_xrpl(value: str | Dict[str, Any]) → BM¶

Creates a BaseModel object based on a JSON-like dictionary of keys in the JSON format used by the binary codec, or an actual JSON string representing the same data.

Parameters:: value – The dictionary or JSON string to be instantiated.
Returns:: A BaseModel object instantiated from the input.

classmethod is_dict_of_model(dictionary: Any) → bool¶

Checks whether the provided dictionary is a dictionary representation of this class.

Note: This only checks the exact model, and does not count model inheritance. This method returns False if the dictionary represents a subclass of this class.

Parameters:: dictionary – The dictionary to check.
Returns:: True if dictionary is a dict representation of an instance of this class; False if not.

is_valid() → bool¶

Returns whether this BaseModel is valid.

Returns:: Whether this BaseModel is valid.

issuer: str¶

This field is required.

to_amount(value: str | int | float) → IssuedCurrencyAmount¶

Converts an IssuedCurrency to an IssuedCurrencyAmount.

Parameters:

value – The amount of issued currency in the IssuedCurrencyAmount.

Returns:

An IssuedCurrencyAmount that represents the issued currency and the: provided value.

to_dict() → Dict[str, Any]¶

Returns the dictionary representation of a BaseModel.

If not overridden, returns the object dict with all non-None values.

Returns:: The dictionary representation of a BaseModel.

validate() → None¶

Raises if this object is invalid.

Raises:: XRPLModelException – if this object is invalid.

class xrpl.models.currencies.XRP(*args: List[Any], **kwargs: Dict[str, Any])¶

Bases: BaseModel

Specifies XRP as a currency, without a value. Normally, you will not use this model as it does not specify an amount of XRP. In cases where you need to specify an amount of XRP, you will use a string. However, for some book order requests where currencies are specified without amounts, you may need to specify the use of XRP, without a value. In these cases, you will use this object.

See https://xrpl.org/currency-formats.html#specifying-currency-amounts

currency: str = 'XRP'¶

classmethod from_dict(value: Dict[str, Any]) → XRP¶

Construct a new XRP from a dictionary of parameters.

Parameters:: value – The value to construct the XRP from.
Returns:: A new XRP object, constructed using the given parameters.
Raises:: XRPLModelException – If the dictionary provided is invalid.
