}

Submit an unsigned transaction onchain with a signed payload

Required Associated Types

type Result

A submission result.

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 as SigningTypes>::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<(), ()>>

Submits an unsigned call to the transaction pool.

Object Safety

This trait is not object safe.
