Struct frame_system::CheckNonce[][src]

pub struct CheckNonce<T: Trait>(_);

Nonce check and increment to give replay protection for transactions.

Note that this does not set any priority by default. Make sure that AT LEAST one of the signed extension sets some kind of priority upon validating transactions.
