+### `txpool_inspect`
+
+Returns a textual summary of all pending and queued transactions in the pool, grouped by sender
+address and sorted by nonce.
+
+The summary is free form, implementation-dependent, and meant to be consumed by humans.
+For programmatic access to the transaction pool, use [`txpool_content`](#txpool_content).
+
+#### Parameters
+
+None
+
+#### Returns
+
+`result`: _object_ - transaction pool inspect object with the following fields:
+
+- `pending`: _object_ - map of sender addresses to maps of nonces to human-readable transaction
+  summary strings, for transactions pending inclusion in the next block
+
+- `queued`: _object_ - map of sender addresses to maps of nonces to human-readable transaction
+  summary strings, for transactions scheduled for future execution
