txpool_status

txpool_status returns just two numbers about a Polygon PoS node's transaction pool: the count of pending transactions (ready to be included in a block) and the count of queued transactions (waiting on a nonce gap or other condition), both hex-encoded. It is the lightweight counterpart to txpool_inspect — perfect for a fast read of mempool depth on a low-fee, ~2-second-block network where backlog can shift quickly. Call it against the Polygon mainnet endpoint at https://polygon.therpc.io/YOUR_API_KEY (chain ID 137, 0x89).

Use cases

• Monitor Polygon mempool depth to detect congestion and raise the gas price on outgoing MATIC transactions when the pending count spikes.
• Feed a dashboard gauge showing the current Polygon transaction backlog, polling the cheap pending and queued counts on a short interval.

Errors & troubleshooting

Common pitfalls

• The txpool namespace comes from the Geth family. Polygon's Bor client is Geth-based so it is usually present, but some managed endpoints disable it — be ready for a "method not found" response.
• The counts are point-in-time snapshots and change very fast on Polygon's ~2-second blocks; do not cache them aggressively or you will display stale backlog figures.

Supported networks
