txpool_status - Flow EVM RPC Method
Inspect pending and queued transaction counts in the Flow EVM Gateway transaction pool. Useful for mempool monitoring, congestion analysis, and node health checks.
Returns transaction pool counters for the connected Flow EVM Gateway 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 Flow EVM? Build on the EVM-equivalent layer on Flow blockchain enabling Cadence+Solidity composability with full EVM equivalence on Flow, atomic multi-operation transactions, 40% lower gas fees, and 473% contract growth in 2025.
When to Use This Method
txpool_status is valuable for NFT developers, gaming studios, and Solidity devs seeking Cadence interoperability:
- 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
Request Parameters
This method accepts no parameters.
Response Body
Number of processable transactions currently in the pool
Number of transactions waiting on an earlier prerequisite such as nonce order
