I am wondering if the module will add seed to publickey
and publickey to consensus key or operator key.

Thanks

Hi @hukkinj1
Is the code ready for Stargate? :)

Is it possible to generate seeds words from a keypair?
Cosmostation will not take any privkey, one must enter seed words instead.

I am the receiver of this transaction and I want to spend 0.1 atom from this account. but when I run the following code I get ""signature verification failed; verify correct account sequence and chain-id" error.

curl -X POST "https://lcd.nylira.net/txs" -H "accept: application/json" -H "Content-Type: application/json" -d "{"tx":{"msg":[{"type":"cosmos-sdk/MsgSend","value":{"from_address":"cosmos15wa26mgeuxvtfpnqfle98wupdeeyxzdu7lff9a","to_address":"cosmos15wa26mgeuxvtfpnqfle98wupdeeyxzdu7lff9a","amount":[{"denom":"uatom","amount":"100000"}]}}],"fee":{"gas":"70000","amount":[{"denom":"uatom","amount":"1000"}]},"memo":"","signatures":[{"signature":"8KyuGPORRF5Eakxw5URy9BM0CjDM72pw25PuhXVBGCcZCvxZ/UIsssNR+OO9DH9JUDp89yX/RUMFvbES1MGwhA==","pub_key":{"type":"tendermint/PubKeySecp256k1","value":"A3ouexs2TMGjefw2zBWKNnwSZJgFsMYmf5OHkfwdWTWX"},"account_number":"11335","sequence":"0"}]},"mode":"sync"}"

since I'm sure that my signature is true,the chain-id should be wrong. I can't find the right chain-id. can you help me please?

hi. I use this link to post transaction created by this library. but when I paste the body of transaction at "POST/txs" I get the "TypeError: Failed to fetch" and when I use the curl command I get as a result the code of a HTML file. the transaction I'm trying to post is :

{"tx":{"msg":[{"type":"cosmos-sdk/MsgSend","value":{"from_address":"cosmos1j32hpgtzh4sudpl0658ylr2tdzu65reyy78x50","to_address":"cosmos1j32hpgtzh4sudpl0658ylr2tdzu65reyy78x50","amount":[{"denom":"uatom","amount":"2"}]}}],"fee":{"gas":"70000","amount":[{"denom":"uatom","amount":"1000"}]},"memo":"","signatures":[{"signature":"LY2iTu+6LeMh/s6ASSRlnxJE3aSpTp6Ung0JMIbyPLF+LDI7YH7M+HRzdtc+5kx+V/8fKmWxfAZIqoyNv0Rh3g==","pub_key":{"type":"tendermint/PubKeySecp256k1","value":"A8mdavgH7MjKqgPdZ8Q9T1xihUbiiRzBqnOR5zCGA40p"},"account_number":"11335","sequence":"0"}]},"mode":"sync"}

thanks for your code, but i think some issue from my end, suppose the JSON part can't parse

My code :

privkey = seed_to_privkey(seed, path="m/44'/118'/0'/0/0")
tx = Transaction(
    privkey=privkey,
    account_num=account_number,
    sequence=1,
    fee=0,
    gas=80000,
    memo="",
    sync_mode='BROADCAST_MODE_SYNC',
    chain_id='korellia'
)
tx.add_transfer(
    recipient="kyve13nwxn4tuszwk6s93vk73xxe6xwf3ssauk5hhde", amount=10000
)
pushable_tx= tx.get_pushable()

api_base_url = "https://api.korellia.kyve.network"
headers = {'content-type': 'application/json'}
result = requests.post(api_base_url + "/cosmos/tx/v1beta1/txs", data=pushable_tx, proxies=proxies,headers=headers)
print(result.status_code, result.text)

The result :

400 {
  "code": 3,
  "message": "invalid empty tx",
  "details": [
  ]
}

the Json print:

Hi,
I see REST endpoint /txs has been migrated now and replaced by /cosmos/tx/v1beta1/txs
And that needs enoded transaction string using protobuf. Any plans to support this?

https://docs.cosmos.network/master/migrations/rest.html

Thanks

Currently we use bip32 PyPI library, which requires coincurve, for BIP32 key derivation. We should derive keys without these added dependencies.

how can I get the average fee of the chain using this library or using any curl command?
I searched for this in https://cosmos.network/rpc/v0.37.9 but couldn't find any fee-related "Get" function.

Can any function be implemented to deal with seed words?

At starname (https://starname.me/), we would like to use this library however we need to customize so far the PATH and the HMR
