Find TxPool Nonce Gaps

Compare the latest on-chain nonce with sender nonces in the txpool.

Use txpool nonce-gaps when later transactions are queued and you need to know which nonce is missing.

Use Sender when you want the filtered sender transaction table alongside the nonce gap summary.

Command

rex txpool nonce-gaps \
  --address 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266

Example Output

TXPOOL NONCE GAPS

Sender:         0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266
On-chain nonce: 1

Pool:
  nonce 2        queued   1 tx

Gaps:
  nonce 1 missing

How to Read It

The command compares:

• the latest on-chain nonce from eth_getTransactionCount(address, "latest")
• the sender’s nonces currently present in txpool_content

If the on-chain nonce is 1 and the pool contains nonce 2, nonce 1 is the gap. Until nonce 1 is mined or admitted to the pool, nonce 2 cannot become executable.

When no gaps exist, the command prints:

No missing nonces between the on-chain nonce and highest pooled nonce.
