Stomp functions don't add any backslashes and the script don't return any script related errors. The error returned is from bitcoin core which complains about insufficient funds. However, when I tried to run the commands above manually without the backslashes, bitcoin core complained about json parsing error. So, why running the command by hand with no backslashes, produces errors and running the command without backslashes using the script, don't produce any errors (related with the script code)????

Tomorrow I need to look into this new issue!

ok, enough for today. Time to sleep.

Thanks to both of you.
The reason for this is that quote removal only occurs on the original input words, not the result of expansions. To demonstrate:

Code:
$ echo "Hello, world"
Hello, world
$ VAR='echo "Hello, world"'
$ $VAR
"Hello, world"

It's also worth noting that quote matching is done before any expansion, for example:
Code:
$ QT='"'
$ echo "$QT"
"
$ echo $QT
"

If you save this code a pparam(or make it a function in your script) you can use it to debug what the shell is doing to your parameters before they are passed on to scripts/functions:

Code:
for((i=1;i<=${#};i++))
do
   echo Param $i: ${!i}
done

Code:
$ VAR='"one" "two"'
$ ./pparam $VAR
Param 1: "one"
Param 2: "two"
$ ./pparam "$VAR"
Param 1: "one" "two"
$ ./pparam "one" "two"
Param 1: one
Param 2: two
