Is there a way to figure get more information about a certain transaction from its txn hash? I am noticing lots of stuck transactions. Here is the workflow:

  • txid = web3.eth.send_transaction

  • web3.get_transaction(txid) raises TransactionNotFound error.

When i search for that txid on polygonscan, I don't get anything.

What are the options available to me to debug this? Is the time between send and get like a blackhole?

Usually this means that the node, of which JSON-RPC API you are using, is not broadcasting the transaction to the network.

Reasons may include

  • Very incorrect gas fee

  • Wrong nonce

  • Wrong signature

To debug such problems, run your local JSON-RPC API node, with log level debug. Then submit your transaction against this node and you will see any errors with your transaction in the log files of your node.

  • No. Where would the API get the data in that case, then? Jul 31, 2021 at 8:11
  • Ok. I was thinking that for debugging it could forward all the calls to another node. Aug 1, 2021 at 20:41
