txpool_inspect

When BNB-funded transactions pile up on BNB Smart Chain during a busy PancakeSwap window, txpool_inspect lets you peer straight into the node's mempool. It belongs to the geth-family txpool namespace and returns a human-readable text summary of every pending and queued transaction the node is holding, organised first by sender address and then by nonce. Each entry collapses to a one-line string that names the recipient alongside the BNB value and gas terms. Call it at https://bsc.therpc.io/YOUR_API_KEY on chain ID 56 for an at-a-glance read on what is waiting to be mined versus what sits parked behind a nonce gap.

Use cases

• Track down a stuck BNB Smart Chain transaction by scanning the summary for its sender address and nonce to see whether it sits pending or queued behind a gap.
• Audit exactly what the mempool is holding during a high-congestion incident, reading off recipients and gas terms without parsing full transaction objects.

Parameters

This method takes no parameters. Pass an empty array [].

Errors & troubleshooting

Common pitfalls

• The method lives in the geth-family txpool namespace, so nodes built on other client lineages may not expose it and will reject the call as unknown.
• Its output is shaped for human eyes, not parsers; reach for txpool_content when you need structured, full transaction objects in code.
• A heavily loaded BSC mempool can make the response enormous, so prefer txpool_status when all you want is a lightweight pending-versus-queued count.
