Substrate.NET.Metadata

Project to manage Substrate based blockchain Metadata from V9 to V14

How to use ?

Instanciate metadata classes

Please check the getMetadataAsync() method from the Substrate.NET.API library allows you to get the hexadecimal string representation of the metadata for a given Substrate blockchain. Once you have the hexadecimal string representation of the metadata, you can instantiate the corresponding Metadata class by instanciating the right Metadata class.

stringhexMetadataFromSubstrateNetApi="0x...";varv11=newMetadataV11(hexMetadataFromSubstrateNetApi);varv12=newMetadataV12(hexMetadataFromSubstrateNetApi);varv13=newMetadataV13(hexMetadataFromSubstrateNetApi);varv14=newMetadataV14(hexMetadataFromSubstrateNetApi);

If you are not sure of your metadata version you can call :

stringhexMetadataFromSubstrateNetApi="0x...";varmetadataInfo=newCheckRuntimeMetadata(hexMetadataFromSubstrateNetApi);// metadataInfo.MetaDataInfo.Version.Value -> 11 / 12 / 13 / 14

Compare metadata

You can also compare metadata between each other, but it should be the same major version (compare V12 with V12 and V14 with V14)

The package also provides a MetadataService class that can be instantiated directly or used with dependency injection. Metadata comparison can provide a differential between two versions, including removed or added pallets, as well as more precise information such as function calls that have been renamed. The MetadataService class supports comparison from version 9 to 14.
