txpool_status - Moonriver RPC Method
Inspect pending and queued transaction counts in the Moonriver transaction pool. Useful for mempool monitoring, congestion analysis, and node health checks.
Returns transaction pool counters for the connected Moonriver endpoint. The result separates transactions that are immediately processable (pending) from those waiting on an earlier nonce or other prerequisite (queued).
Non-standard method.
txpool_statusis a Geth-style mempool inspection method. It is not part of the core Ethereum Execution API method set, and many shared RPC endpoints disable it.
Why Moonriver? Build on the Moonbeam canary network on Kusama for real-world testing of EVM dApps with Moonbeam code ships here first, full EVM compatibility on Kusama, 80% fee burn mechanism, and XCM cross-chain messaging.
When to Use This Method
txpool_status is valuable for dApp developers testing on Kusama, early adopters, and teams requiring production-ready experimentation:
- Mempool Monitoring — Watch pending versus queued pressure on a node
- Congestion Signals — Detect bursts of transaction backlog before they show up in block-level metrics
- Node Health Checks — Confirm a node is accepting and classifying new transactions as expected
- Operational Dashboards — Surface lightweight txpool counters without pulling full transaction content
Code Examples
Error Handling
| Error Code | Message | Description |
|---|---|---|
| -32601 | Method not found | The endpoint does not expose txpool methods |
| -32603 | Internal error | The node rejected or failed to process the request |
