I tested sending multiple transactions with a low time gap, and I knew that they will wait for previous transactions to be confirmed. I did not use Nonce in the transaction code as it is optional. But I would like to know, is there any way to send transactions without waiting for confirmation of previous ones?
I thought about using nonce = getTransactionCount() + 1, although, I am not sure is it correct or not? and which condition I have to set in it amoung latest, earliest or pending for this solution.

Web3.js does it for you if you do not specify nonce explicitly, so it won't make any difference.

Yes, exactly as you described it (sending them without waiting for confirmation of previous ones).

  • Thanks for reply. Do you mean I should not do anything special to achieve my goal? – Mohammad Saberi Apr 14 at 10:35
  • @MohammadSaberi: Yup, simply don't wait for confirmation. Just keep the transaction hash (which is returned to you pretty much instantly), and check it later. Alternatively you can just check the state variables that your transactions change (assuming that each transaction independently changes something in the state). – goodvibration Apr 14 at 10:37
  • Your direct and clear answer help me a lot. Thank you – Mohammad Saberi Apr 14 at 10:39
  • @MohammadSaberi: You're welcome. Note that in this scheme you WILL need to increment the nonce explicitly, but WITHOUT relying on getTransactionCount for that (i.e., use your own internal counter). – goodvibration Apr 14 at 10:39

    @MohammadSaberi: Web3 does it automatically (setting nonce to the value returned by getTransactionCount). But the nonce of your account will not really increment until the transaction is added to the blockchain, and until that happens, getTransactionCount will return the same value. – goodvibration Apr 14 at 11:57
