Python library with tools for Feathercoin.

1) pycoin library https://github.com/richardkiss/pycoin

add FTC in pycoin/networks.py

    # FTC feathercoin mainnet : xprv/xpub
    NetworkValues("Feathercoin", "mainnet", "FTC", b'\x8e', b'\x0e', b'\x60', h2b('0488ADE4'), h2b('0488B21E')),
    # FTC feathercoin testnet : tprv/tpub
    NetworkValues("Feathercoin", "testnet", "FTX", b'\xC1', b'\x41', b'\xc4', h2b('04358394'), h2b('043587CF')),

2) pybitcoin library https://github.com/namesystem/pybitcoin

add FTC in coinkit/privatekey.py and publickey.py

class FeathercoinPrivateKey(BitcoinPrivateKey):
    _pubkeyhash_version_byte = 14

class FeatherPublicKey(BitcoinPublicKey):
    _version_byte = 14

How to use it ?

The command line utility â€œkuâ€

The most basic form of a Feathercoin private key is simply an integer between 1 and 115792089237316195423570985008687907852837564279074904382605163141518161494336 â‰… 1.15e77 (inclusive). Thatâ€™s it! This integer is a â€œsecret exponentâ€, because generating the public key involves exponentiation, and there is no known way to go from the public key to the secret exponent.

Letâ€™s take a look at the very first private key, also known as â€œ1â€.
