Python Polymath SCALE Codec
Python Polymath SCALE Codec Library
Description
Most of the data that the Substrate RPCs output is encoded with the SCALE Codec. This codec is used by the Substrate nodes' internal runtime. In order to get to meaningful data this data will need to be decoded. The Python SCALE Codec Library will specialize in this task.

Examples
Decode a SCALE-encoded Compact<Balance>
RuntimeConfiguration().update_type_registry(load_type_registry_preset("default"))
RuntimeConfiguration().update_type_registry(load_type_registry_preset("kusama"))
obj = ScaleDecoder.get_decoder_class('Compact<Balance>', ScaleBytes("0x130080cd103d71bc22"))
obj.decode()
print(obj.value)
Add custom types to type registry
RuntimeConfiguration().update_type_registry(load_type_registry_preset("default"))
custom_types = {
"types": {
"MyCustomType": "u32",
"CustomNextAuthority": {
"type": "struct",
"type_mapping": [
["AuthorityId", "AuthorityId"],
["weight", "AuthorityWeight"]
]
}
}
}
RuntimeConfiguration().update_type_registry(custom_types)
Or from a custom JSON file
