Module broadcast_tx_async

Sends asynchronous transactions.

Example

Constructs a signed transaction to be sent to an RPC node. It returns the transaction hash if successful.

This code sample doesn’t make any requests to the RPC node. It only shows how to construct the request. It’s been truncated for brevity sake.

A full example on how to use broadcast_tx_async method can be found at contract_change_method.
