Hi, it doesn't work with p2wpkh-p2sh, p2sh private keys

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):
File "C:\Sundar\BTC\bitcoin_fork_claimer-master\claimer.py", line 1356, in
rawaddr = b58decode(destaddr)
File "C:\Sundar\BTC\bitcoin_fork_claimer-master\claimer.py", line 68, in b58decode
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?

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.
