txpool_status

txpool_status returns the number of pending and queued transactions in an Avalanche C-Chain node's transaction pool, as two hex-encoded integers. Pending transactions are ready for inclusion in the next block; queued ones are waiting on a nonce gap or other condition. It is the lightweight counterpart to txpool_inspect — just the totals, no per-transaction detail — which makes it ideal for cheap, frequent polling of mempool depth. On the C-Chain, the EVM chain where AVAX pays for gas under Snowman/Avalanche consensus, these counts give a quick read on congestion.

Use cases

• Poll mempool depth on the C-Chain to detect congestion and raise the gas price on outgoing AVAX transactions when the pending count climbs.
• Feed a dashboard gauge that shows the current C-Chain transaction backlog at a glance, using the pending and queued counts as a real-time congestion signal.

Errors & troubleshooting

Common pitfalls

• The txpool namespace is Geth-style. Avalanche C-Chain's coreth client is Geth-derived, but not every endpoint enables it, so a node without the namespace returns "method not found".
• The counts are instantaneous snapshots that shift quickly as the C-Chain produces blocks every one to two seconds. Do not cache them aggressively — re-poll when you need a current reading.
