Submit

Submit a Signed Transaction

Submit a pre-signed transaction to the node. This call should not block on the transaction being included in a block. Rather, it should return immediately with an indication of whether or not the transaction was included in the mempool. The transaction submission response should only return a 200 status if the submitted transaction could be included in the mempool. Otherwise, it should return an error.
