Hi. Did you solve it?
No, I ended up using py-injective for this particular wallet, cosmpy for the other ones.
same issue here
OK after reading the source of a few libraries I have figured this out. For unknown to me reason comspy and Injective use different hashing strategies for address derivation. Here is a reproduction of this issue:
import sha3
from bip_utils import Hash160
from pyinjective import PrivateKey as InjectivePrivateKey
from cosmpy.crypto.address import Address as CosmpyAddress
from cosmpy.crypto.keypairs import PrivateKey as CosmpyPrivateKey
def via_injective(private_key_hex: str) -> str:
priv_key = InjectivePrivateKey.from_hex(private_key_hex)
pub_key = priv_key.to_public_key()
return pub_key.to_address().to_acc_bech32()
def via_cosmpy(private_key_hex: str) -> str:
private_key = CosmpyPrivateKey(bytes.fromhex(private_key_hex))
public_key = private_key.public_key
return str(CosmpyAddress(public_key, prefix="inj"))
def keccak256(pubkey: bytes) -> bytes:
keccak_hash = sha3.keccak_256()
keccak_hash.update(pubkey[1:])
return keccak_hash.digest()[12:]
def via_bip_utils(private_key_hex: str, hrp="inj", use_keccak=False) -> str:
from bip_utils import Secp256k1PrivateKey, Bech32Encoder
import binascii
# Decode the hex string to bytes
private_key_bytes = binascii.unhexlify(private_key_hex)
# Create a private key object
private_key = Secp256k1PrivateKey.FromBytes(private_key_bytes)
# Get the public key from the private key
public_key = private_key.PublicKey()
# Hash the public key using SHA256, then RIPEMD-160 or keccak256
pub_key_hash = keccak256(public_key.RawUncompressed().ToBytes()) if use_keccak else Hash160.QuickDigest(public_key.RawCompressed().ToBytes())
# Convert the hash of the public key to an address using bech32 encoding
return Bech32Encoder.Encode(hrp, pub_key_hash)
private_key = "1112f3b9df973c25c5423f9c1ed5eb46b64059ba28a1b5870c525c816f9dbb52"
print("Injective lib", via_injective(private_key))
print("compy", via_cosmpy(private_key))
print("manual via keccak256", via_bip_utils(private_key, use_keccak=True))
print("manual via ripemd160", via_bip_utils(private_key, use_keccak=False))
Output is:
Injective lib inj1ftqt0zhaa7dvnx77q8y5ls2ups5khdx7wk8n4l
compy inj1pkczxghy5ms2fy3cqtty0l6kxqg4wa9eetwpx2
manual via keccak256 inj1ftqt0zhaa7dvnx77q8y5ls2ups5khdx7wk8n4l
manual via ripemd160 inj1pkczxghy5ms2fy3cqtty0l6kxqg4wa9eetwpx2
Would love to hear somebody's opinion on why this might be the case!
yes I noticed the same thing here
Prerequisites
Expected Behavior
Injective support was added by the developer of bip_utils, which now allows to generate the expected addresses from a mnemonic.
from cosmpy.aerial.wallet import LocalWallet from cosmpy.crypto.keypairs import PrivateKey, PublicKey from bip_utils import Bip39SeedGenerator, Bip44, Bip44Coins
mnemonic = "24 WORDS HERE" seed_bytes = Bip39SeedGenerator(mnemonic).Generate()
bip44_mst_ctx = Bip44.FromSeed(seed_bytes, Bip44Coins.INJECTIVE) bip44_acc_ctx = bip44_mst_ctx.Purpose().Coin().Account(0) bip44_chg_ctx = bip44_acc_ctx.Change(Bip44Changes.CHAIN_EXT)
bip44_addr_ctx = bip44_chg_ctx.AddressIndex(0) #index 0 appears to be the right one here
print(bip44_addr_ctx.PublicKey().ToAddress()) # --> CORRECT ADDRESS
print(LocalWallet(PrivateKey(bip44_addr_ctx.PrivateKey().Raw().ToBytes()), prefix='inj')) #--> WRONG ADDRESS The above is expected to print the same address twice.
Current Behavior
Using LocalWallet the generated address is incorrect. This seems to be related to the fact that Cosmpy uses the Atom address encoder.
Running this code generates the same address than LocalWallet:
from bip_utils import AtomAddrEncoder
print(AtomAddrEncoder.EncodeKey( bip44_addr_ctx.PublicKey().Bip32Key().KeyObject(), hrp="inj" ))

Context
Tested on Ubuntu 23.04 with python3.11 and latest Fetchd and bip_utils.
Do you know of a workaround to this issue?
