Response
result— a string representing the filter ID. This ID should be used in subsequent calls to eth_getFilterChanges to retrieve new pending transactions.
Use case
The eth_newPendingTransactionFilter method is useful for applications that need to monitor the mempool for new transactions. Common use cases include:
- Building transaction monitoring tools
- Creating real-time transaction tracking interfaces
- Implementing MEV (Maximal Extractable Value) strategies
- Monitoring specific addresses for pending transactions
Note: After creating the filter, you need to poll eth_getFilterChanges periodically to get updates. Filters timeout if they're not used for a period of time, so applications should be prepared to recreate them if necessary.
