Hi, I did a little change in order to be easier to adapt to the needs of the user. In practice I specify the addresses and the private keys in a comma separated value text file as well as the fork_list adding also the address to send.
I load then the two files with

with open('keys') as f:
    lines = f.read().splitlines()
wallet={}
for line in lines:
    addr, key = line.split(',')
    wallet[addr]=key

with open('fork_list') as f:
    lines = f.read().splitlines()
fork_list={}
for line in lines:
    if line[0] != '#':
        coin, name, block, address = line.split('#')[0].split(',')
        fork_list[coin]={'name': name, 'block': int(block), 'address': address}

and I call the address of the fork as

coindata["commands"].append("python claimer.py " + coincode + " " + " ".join(value) + " " + fork_list[coincode]['address'])

and the private key as

valid.append([tx["hash"], wallet[addr], addr])

Maybe you can add this as an option in your code.

claimer.py is not accepting bch addr.
I added BCH fork details to your script.

Getting below error when trying with a BCH dest address

Candidate transaction, index 1 with 107889 Satoshis (0.00107889 BTC)
Traceback (most recent call last):

n = n * 58 + b58ab.index(c)
ValueError: substring not found

Hi, very much appreciate the tool, in combination with fork_claimer excellent,
EXCEPT... it is worthy to mention that blockchain API limits the number of TXIDs to 50 !!! and thus the tool does not further show older/remaining TXIDs;
I needed to manually modify and add "?offset=50/100/etc to get all TXIDs ;
just needed to mention this ;-)

Can you add support for CLAMS?

Done.

To all others that commented before, I'm sorry but I didn't see your messages. This is the first time I received an e-mail about someone saying something here.
