I’m attempting to transform the 12 phrases into BTC addresses, however they don’t match those proven to me by Safepal, Coinomi, and Belief Pockets. I’ve tried utilizing a number of libraries and doing it manually.
I managed to efficiently convert to SegWit, however P2PKH and P2SH nonetheless don’t match.
The phrases (they’re for testing functions) are:
false deal summary advance buffalo clock auto banana supply area wage stumble
The code I’m utilizing to transform utilizing the 2 strategies that aren’t working is as follows:
################# P2PKH ##############
seed = hashlib.pbkdf2_hmac('sha512', mnemonic.encode('utf-8'), b'mnemonic', 2048)
private_key = seed[:32]
public_key = hashlib.sha256(private_key).digest()
ripemd160 = hashlib.new('ripemd160')
ripemd160.replace(public_key)
hash160 = ripemd160.digest()
model = b"x00" # model for P2PKH addresses on Bitcoin mainnet
address_bytes = model + hash160
checksum = hashlib.sha256(hashlib.sha256(address_bytes).digest()).digest()[:4]
addressP2PKH = base58.b58encode(address_bytes + checksum).decode('utf-8')
################ P2SH ##############
seed = hashlib.pbkdf2_hmac('sha512', mnemonic.encode('utf-8'), b'mnemonic', 2048)
private_key = seed[:32]
sk = SigningKey.from_string(private_key, curve=SECP256k1)
vk = sk.get_verifying_key()
public_key_bytes = vk.to_string()
hashed_public_key = hashlib.sha256(public_key_bytes).digest()
ripe_hash = hashlib.new('ripemd160', hashed_public_key).digest()
prefix = b'x05'
prefixed_ripe_hash = prefix + ripe_hash
address_bytes = hashlib.sha256(prefixed_ripe_hash).digest()
address_bytes = hashlib.sha256(address_bytes).digest()
checksum = address_bytes[:4]
raw_address = prefixed_ripe_hash + checksum
addressP2SH = base58.b58encode(raw_address).decode()
print(['segwitAddress', 'addressP2PKH', 'addressP2SH'])
The output is:
['bc1qfev3mh2mz3cuvsfn3wt6rwv78qjlkcy7dj27dk', '14ZowctPoxYtaUa55XKpUq8h2VWzPvLQ84', '37qZKk7ZpFFX63fR4HLPRaU5jtdhckmcnP']
But it surely needs to be:
['bc1qfev3mh2mz3cuvsfn3wt6rwv78qjlkcy7dj27dk', '1D9P3s1Daa3dmLq88QAky3uv4vjT6WZRCV', '3HojBjoLmEHjrHfiiUKAL1NCVXEcmAf7iY']
