​
Use case

The wallet/getpendingsize method is used for:
  • Monitoring network congestion by tracking the number of pending transactions.
  • Building network analytics dashboards that display mempool statistics.
  • Implementing adaptive fee strategies based on current network load.
  • Creating alerts for high network congestion periods.
  • Optimizing transaction timing for applications based on mempool size.
The pending pool size fluctuates constantly as new transactions are submitted and existing ones are confirmed or dropped. A larger pending size typically indicates higher network congestion and may suggest longer confirmation times.
