Expand description

Submit an unsigned transaction onchain with a signed payload

Associated Types

A submission result.

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

Required methods

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

Submits an unsigned call to the transaction pool.
