TransactionExtensionMetadata class

Metadata about a transaction extension (V16)

Transaction extensions replace signed extensions in V16. They provide a more flexible mechanism for extending extrinsic functionality. Each extension can contribute both explicit data (included in the extrinsic) and implicit data (derived and included in the signed payload).
