Script doesn't seem to be working 100%

Check this thread: https://bitcointalksearch.org/topic/help-with-bitcoin-transaction-5159518

For some reason it is detecting the beginning of the transactionID: e7a3e5b1a2f7c2aa5fa9ebf1cc31c123a83367502c7648dfb6c1baa0ff3e8436 as a bitcoin address and attempting to generate the balance image for it??!?

This is what I see:



Also, from looking at the "Stake Your Address" thread, it is breaking URLs with addresses in them, for instance Block Explorer links:
So, this URL:

is actually encoded as:
https://www.blockchain.com/btc/address/384pXJVj7H49Sp9p9v5RnkbozM3ioVcgnL%20%3Cimg%20src='https://btc.ninjastic.space/balance/384pXJVj7H49Sp9p9v5RnkbozM3ioVcgnL/ff0000'/%3E


and it is also struggling with large blocks of "hex"... like GPG keys etc:


and Signed Messages:



Not sure if this is a Chrome/Tampermonkey specific issue.

I've made my own "bitcoin balance image" server that also supports Segwit addresses (bech32 included). In case you want to use in your script.

Code:

Hmm... it’s working here. Can you try opening it directly?

regex is not enough since it can only check validity of characters. i don't know how JavaScript works but basically you need to add a function instead of that one liner to decode the strings using Base58 encode/decode technique which would mean converting it to its numerical value then hashing the byte array using SHA256 twice and taking 4 bytes of it as checksum then see if it is correct. then pass it to get the balance. more info: https://en.bitcoin.it/wiki/Base58Check_encoding

i didn't mention Bech32 since the btc-priceimg and the blockchain.info API it uses don't support them but here is the link to its documentation: https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki

try this one:
Code:
^([13][a-km-zA-HJ-NP-Z1-9]{25,34}|bc1[ac-hj-np-zAC-HJ-NP-Z02-9]{11,71})$
I found it here:
http://mokagio.github.io/tech-journal/2014/11/21/regex-bitcoin.html

You can also verify whether the address is valid or not by checking its checksum.


thank you so much, today i dont have spare time for update it, i'll try tomorrow
is a simple regex sobstitution for catch bc1xxxx address

and after i'll study a method for TX

you might want to add some more encoding checks (base58 and bech32 if you could add it) to the values you capture as "addresses" instead of a simple regex check for characters. right now it seems like it is possible to catch something like a transaction ID that starts with 1 or 3 (32 byte and having 0-9 and a-f) as an address.

SegWit addresses don't work  Sad
Because the script uses blockchain.info's API which does not support segwit.
