txpool_inspect

Last updated:

txpool_inspect lists the transactions the backing Ethereum node is holding in its mempool, grouped into pending (executable now) and queued (not yet executable, e.g. a nonce gap). The result is keyed by sender address and then by nonce. Each transaction is rendered as a short, human-readable string rather than a full transaction object — recipient: value wei + gas × gasPrice wei.

Use it for a quick, low-bandwidth overview of mempool state: which senders have transactions in flight, at which nonces, and at what value and price. When you need the full structured transaction objects (input data, signatures, fee fields, etc.) call txpool_content instead; for just the pending/queued counts call txpool_status.

This method belongs to the eth_txpool category and is restricted to the Pro tier and above. The data reflects the specific node serving your request — the mempool is local to each node, varies continuously, and is not consensus state, so successive calls (and calls hitting different nodes) will differ. It takes no parameters.

Parameters

This method takes no parameters.

Examples

curl https://triport.io/sol \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"id":1,"method":"txpool_inspect","params":[],"jsonrpc":"2.0"}'
const res = await fetch("https://triport.io/sol", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
  "id": 1,
  "method": "txpool_inspect",
  "params": [],
  "jsonrpc": "2.0"
}),
});
const data = await res.json();
import requests
resp = requests.post(
    "https://triport.io/sol",
    headers={"Authorization": "Bearer <api-key>"},
    json={"id":1,"method":"txpool_inspect","params":[],"jsonrpc":"2.0"},
)
print(resp.json())
