cosmospy's Issues

run with python version 3.10, get issue.

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:

{
  "tx": {
    "msg": [

            }
          ]
        }
      }
    ],

        },

keypair to seed words

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

how to get account_num and sequence

Will the module add some functions?

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

Thanks

Write BIP32 key derivation without added dependencies

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

signature verification failed

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?

REST endpoint migration

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

problem at broadcasting

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"}

Seed words

Can any function be implemented to deal with seed words?

getting the average fee of the network

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.

being able to configure the PATH and the HMR to include other cosmos network

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

Support to Stargate

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