Expand description

Something that acts like an Extrinsic.

Associated Types

The function call.

The payload we carry for signed extrinsics.

Usually it will contain a Signature and may include some additional data that are specific to signed extrinsics.

Provided methods

Is this Extrinsic signed? If no information are available about signed/unsigned, None should be returned.

Create new instance of the extrinsic.

Extrinsics can be split into:

  1. Inherents (no signature; created by validators during block production)
  2. Unsigned Transactions (no signature; represent “system calls” or other special kinds of calls) 3. Signed Transactions (with signature; a regular transactions with known origin)
