First of all, I want to thank you for your attention and time.
I think there are some problems with this pull request that I tried to specify them. In some parts, it seems that the performance has decreased, also in some parts, the nested codes have reduced the code readability

this way has more indent and i thinks original way has much cleaner code

original way is cleaner and more Rusty

still i think original way is cleaner and more readable.it has less indent and if works like guard.

max count is 10 and seems is was remove in your code

this way has performance issue. if url doesn't exist it check for empty string in short.
why we add extra search in blockchain data while we know it is empty
