txpool_status - Immutable RPC Method
Inspect pending and queued transaction counts in the Immutable transaction pool. Useful for mempool monitoring, congestion analysis, and node health checks.
Returns transaction pool counters for the connected Immutable 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 Immutable? Build on the gaming-optimized zkEVM with 660+ games, 5.5M+ Passport signups, and $40M TVL with first EVM chain with enforceable royalties, Polygon zkEVM technology, $2B+ ecosystem funding, and Agglayer cross-chain liquidity.
When to Use This Method
txpool_status is valuable for AAA game studios, indie game developers, and NFT gaming teams seeking enforceable royalties:
- 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
