problem create address from mnemonic CARDANO

[Noname400]

I ask for help. since I don't understand why the address is not generated correctly.

this code
`# Generate seed from mnemonic
seed_bytes = Bip39SeedGenerator(mnemonic).Generate()
coin_type = Bip44Coins.CARDANO_BYRON_ICARUS
bip32_ctx = Bip32Slip10Secp256k1.FromSeed(seed_bytes).DerivePath(f"m/44'/1815'/0'/0/0")
priv_key_bytes_ = bip32_ctx.PrivateKey().Raw().ToHex()
priv_key_bytes = bip32_ctx.PrivateKey().Raw().ToBytes()
pub_key_bytes = bip32_ctx.PublicKey().RawCompressed().ToBytes()
print(f"Derived private key (bytes): {priv_key_bytes_}")
print(f"Derived public key (extended): {pub_key_bytes}")

#s = binascii.unhexlify(pub_key_bytes)
bip44_ctx = Bip44.FromPublicKey(pub_key_bytes[1:], coin_type)
print(f"Address: {bip44_ctx.PublicKey().ToAddress()}")`

I get the correct private key. but how do I get the address in a different format. the test address is listed above.

What do you use to generate the cardano address? Yoroi does not support 12 words, only 15 and 24

[Noname400]

I took all the data from exodus
in exodus I used 12 words
maybe the problem is that when generating in exodus the path 1825/1815 is used and not 44/1815

[Noname400]

it is possible to generate BYRON
and get the address in Shelley format

[Emanuele Bellocchia]

When you use wallets like Exodus and Atomic it happens that they derive keys in their own ways, so they are not compatible with other wallets.
If you check the derivation path of Cardano in Exosdus page there is an asterisk indicating that is has a non-standard path.

[Emanuele Bellocchia]

It's not easy to understand what they are doing, because Cardano has many ways to generate the seed and derive keys as you can see from the readme. So, I don't know which algorithm they use to derive keys and which one for generating the seed, it's not just a matter of changing the derivation path to 44'. Moreover, the Shelly address also needs the staking key beside the public key, so you should understand also how the staking key is generated.

import binascii
from bip_utils import Bip44Changes, Bip44Levels, Cip1852Coins, Cip1852

seed_bytes = binascii.unhexlify(b"0000000000000000000000000000000000000000")
cip1852_mst_ctx = Cip1852.FromSeed(seed_bytes, Cip1852Coins.CARDANO_ICARUS)

print(cip1852_mst_ctx.PrivateKey().Raw().ToHex())
print(cip1852_mst_ctx.PublicKey().RawCompressed().ToHex())
print(cip1852_mst_ctx.PublicKey().ChainCode().ToHex())

print(cip1852_mst_ctx.Level())
print(cip1852_mst_ctx.IsLevel(Bip44Levels.MASTER))

cip1852_acc_ctx = cip1852_mst_ctx.Purpose().Coin().Account(0)
print(cip1852_acc_ctx.PrivateKey().Raw().ToHex())
print(cip1852_acc_ctx.PublicKey().RawCompressed().ToHex())

cip1852_chg_ctx = cip1852_acc_ctx.Change(Bip44Changes.CHAIN_EXT)

for i in range(5):
cip1852_addr_ctx = cip1852_chg_ctx.AddressIndex(i)
print(cip1852_addr_ctx.PrivateKey().Raw().ToHex())
print(cip1852_addr_ctx.PublicKey().RawCompressed().ToHex())
print(cip1852_addr_ctx.PublicKey().ChainCode().ToHex())
try:
print(cip1852_addr_ctx.PublicKey().ToAddress())
except ValueError:
pass

this example not work!

I have no problem running it, what do you mean?
