Subscribe to transaction logging to receive notifications when transactions occur that match specified filter criteria. This method establishes a persistent WebSocket connection that will send real-time log notifications whenever transactions matching your filters are processed by the network. You can filter by all transactions, transactions with votes, or transactions mentioning specific accounts.
