If you want to generate private keys, you can use bitcash from sporestack

bchmemo's Issues

ConnectionError: All APIs are unreachable.

Trying a pretty simple test case:

from bchmemo import MemoUser
user=MemoUser('bitcoincash:used an address here')
user.private_key = 'used WIF Compressed here'
user.get_memos()

Gets
Traceback (most recent call last):
File "get_posts.py", line 5, in
user.get_memos()
File "/home/my_dir/.local/lib/python3.6/site-packages/bchmemo/memouser.py", line 61, in get_memos

Is this package abandoned?

user.post_memo() throws an error: sanitize_tx_data() got an unexpected keyword argument 'custom_pushdata'

I got the below error when trying to post a memo. I got a similar error when I tried to use set_name().

user.post_memo('sth') throws an error: 'Specify rawtx parameter'

I'm following the example from the readme, but when I try posting a memo, I keep getting this error:

>>> user.post_memo('sth')

Seems to consolidates all utxos and makes a lot of inputs.

as I understand from bitcash/bit lib guide it should combine all utxos as default, but I have received 53 inputs and -> bigger tx fees.

How to combine all utxos into 1 or choose biggest unspent to have just 1 input for tx?!

example tx with 53 inputs https://bch.btc.com/96c791c88cc5a552813cb94c25e06524ce59a5b06ac909ddcece5a47ca2595d2
