Struct frame_system::CheckMortality
source · pub struct CheckMortality<T: Config + Send + Sync>(pub Era, _);
Expand description
Check for transaction mortality.
The extension adds [Era
] to every signed extrinsic. It also contributes to the signed data, by
including the hash of the block at [Era::birth
].
§Transaction Validity
The extension affects longevity
of the transaction according to the [Era
] definition.
