i have seen in forum.cardano someone giving the parameter --change-address and explaing that we dont have to calculate the fee.
does anyone can verify this for mainnet and this current moment, if that works?
also my understanding is, we will give input, then the output to the recipient(s) and the rest goes to my address (in --change-address)
for the example below, we see a mint Token. can we use --change-address for any transaction? also only to send ADA?
cardano-cli transaction build
--tx-out $address+$output+"$tokenamount $policyid.$tokenname"
do we need also the "--alonzo-era " ?
