Fee and Smart Filters

Can I set a minimum fee per smartfilter? so that it is customizable?
asked Dec 31, 2018 by suscitar
Can you please clarify what you mean by a "fee per smart filter". Do you mean a fee for creating the filter, or that the filter imposes a fee on particular types of transactions?
Normally, you can set a rate for sending assets, but this rate is not customizable, I wanted to know if I had a filter to analyze the rate inserted in the transaction and accept or not depending on the value.

Yes, you can check the transaction fee (using raw blockchain units, which we recommend) as follows:

function filtertransaction()
  var bal=getfilterassetbalances("", true);
  var fee=0;
  for (var add in bal)
  if (fee < 1000)
    return "Insufficient Fee!";

may seem like a stupid question, but how do I run a code like this? (several lines)
If you're using multichain-cli, it's indeed tricky to use multi-line code. So just remove the new lines and use spaces instead, the JavaScript means exactly the same.
when i send aprovefrom , return The transaction was rejected: 64: The transaction did not pass filter filter1: Insufficient Fee!
You cannot approve a filter that would reject the transaction that performs the approval. So in this example you would need to have a fee of at least 1000 raw native currency units on the approve transaction.
would I be able to mount this transaction at a higher fee, or just with the command settxfee?
Yes, you could send the approval if you attach a higher fee to the transaction making the approval.
