Tx submission timing (+during congestion)

[xdzurman]

Hello!

Please, when you submit an invalid tx through txClient.submitTx(tx) during network congestion, how does the validation work? Do you immediately get the response that the tx is malformed / utxos are spent / ... ? Or does this validation occur later, so you have to wait e.g. 5 minutes regardless of tx submission success or failure?

Thanks!

It should occur immediately since the validation is local. A transaction is only added to a node's mempool if and only if it is well-formed and valid. Thus, this happens before any congestion. This is also true for phase-2 validations (Plutus scripts) and scripts evaluation in general.
