Submit an unsigned transaction onchain with a signed payload

Associated Types

Should contain the submission result and the account(s) that signed the payload.

Required methods

fn send_unsigned_transaction<TPayload, F>(
    &self,
    f: F,
    f2: impl Fn(TPayload, T::Signature) -> LocalCall
) -> Self::Result where
    F: Fn(&Account<T>) -> TPayload,
    TPayload: SignedPayload<T>, 

Send an unsigned transaction with a signed payload.

This method takes f and f2 where:

• f is called for every account and is expected to return a SignedPayload object.
• f2 is then called with the SignedPayload returned by f and the signature and is expected to return a Call object to be embedded into transaction.

Provided methods

fn submit_unsigned_transaction(&self, call: LocalCall) -> Option<Result<(), ()>>
