how can I calculate it, I just want to know the fee of a transaction pull from chain🤣

Edison Lim

@edisonljh

My message above.

So example:
If your transaction costs 1000 Gas according to the interpreter, and the gas price that you placed was 1,000 Li, then the gas cost to you for the transaction will be

1,000 * 1,000 * 10^-6  = 1 Zil.

That's the mathematical way to go around it. If you want it to be simpler, send a transaction on the devnet. The viewblock will show you the cost breakdown (in both Zils and USD)

I knew it, but I want to get the "Gas" I used by RPC, the response only contain the "gas_limit" filed.

does "gas_limit" == "gas I spent"?

@Meai1

which wallet is official? they all look unofficial to me: https://chrome.google.com/webstore/search/zilliqa

We operate similar to Ethereum. There is no official wallet. I will recommend Moonlet, it’s akin to Metamask.

what's the fastest way to develop locally? I tried using kaya rpc server but it doesnt seem to work together with the javascript SDK as far as I can tell. I want to deploy contracts quickly (much quicker than 1min blocktime)

evesnow91

@evesnow91

For contract development, I recommend following the contract testing methodology in Scilla binary via easyrun. For dapps testing, Kaya rpc will be revamped soon so they can work together. Please make do with the dev testnet for now.

@leeduckgo

for example: the field in the return of api of ethereum is "gas". it's make sense, because this is the gas actually used in transaction.

https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_gettransactionbyhash

But the return of zilliqa, there is only "gas limit" and "gas price".

https://apidocs.zilliqa.com/#gettransaction

That is confusing.

Hi, In the python api scripts for zilliqa to create transaction what do I set the chain to in "set _active _chain" if I am running a local network .
from pyzil.crypto import zilkey
from pyzil.zilliqa import chain
chain.set_active_chain(chain.MainNet)

my_key = zilkey.ZilKey(private_key="**")

payload = {
"to_addr": "4baf5fada8e5db92c3d3242618c5b47133ae003c",
"amount": "1000000000000",
"gas_price": "1000000000",
"gas_limit": 1,
"code": "",
"data": "",
"priority": False,
}

params = chain.active_chain.build_transaction_params(my_key, **payload)
txn_info = chain.active_chain.api.CreateTransaction(params)
print(txn_info)

I understand I could use this way " new_api = ZilliqaAPI(endpoint="http://localhost:4201") " but in the github file of pyzil I did not get the script for creating transaction locally.

github link for low level api's: https://github.com/deepgully/pyzil/blob/master/pyzil/tests/test_lowlevel_api.py

I have raised a github issue for the same at deepgully/pyzil#4 .
Please help.

@evesnow91

You have to pack the bytes for VERSION I think

This is how you do transaction @kishankumar258
https://github.com/deepgully/pyzil#zils-transaction

One way is to add localhost yourself after MainNet here:
https://github.com/deepgully/pyzil/blob/c712f5f0dac382ca2ee038343ef2a4cccc154437/pyzil/zilliqa/chain.py#L113

@evesnow91

LocalNet = BlockChain("http://localhost:4201",
                     version= 131073, network_id= 2)

Then:

chain.set_active_chain(chain.LocalNet)

kishankumar258

@kishankumar258

Should not the network id be "2" as received as the output of "new_api.GetNetworkId()"

evesnow91

@evesnow91

Yep

Changed it

kishankumar258

@kishankumar258

Thanks

evesnow91

@evesnow91

packed bytes of (2,1) is 131073

gas in Ethereum is gasLimit*gasPrice

@albertschr

kishankumar258

@kishankumar258

@evesnow91 After doing this I get this error
chain.set_active_chain(chain.LocalNet)
AttributeError: module 'pyzil.zilliqa.chain' has no attribute 'LocalNet'

I had forked the pyzil repo made changes and then setup pyzil.

@neeboo

@albertschr cumulative_gas is the gas amount that consumed.

@albertschr This might help. Just implemented yesterday. https://dev-wallet.zilliqa.com/calculate

hi, love this project and trying to understand the code. In the new mainnet, they use bech32 for the address. Can someone point out to me in which file they appended the zil prefix to the address. thanks!

What is the checksum address in zilliqa local network?
I am able to get the address of a node from the zilliqa logs in the local run folder and also able to check balance ( using GetBalance) for this addresss associated with a node, but, while sending transactions it shows as an invalid checksum address .I tried prepending "0x" to the address but that also shows as an invalid address. Is it something else for the local network, or do I need to do something else in this case. I am using the python client pyzil.

evesnow91

@evesnow91

# to_addr must be bech32 address or 20 bytes checksum address
to_addr = “zil1k5xzgp8xn87eshm3ktplqvs9nufav4pmcm52xx"

@kishankumar258 use https://github.com/deepgully/pyzil/blob/master/pyzil/crypto/zilkey.py#L87

I met a problem when I am going to sign the transaction with Zilliqa.

Because the schnorr signature don't had library in language I using.\

So, is it necessary to sign Transction with Schnorr signature, or something else is Okay?

Because BCH is using schnorr too and the traditional signature is valid, too.

evesnow91

@evesnow91

BCH Schnorr implementation is diff from Zilliqa's

What language are you using?

李大狗

@leeduckgo

Elixir🤣

Can I using this library?
