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.

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.

@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?

https://github.com/cculianu/secp256k1

Bitcoin-ABC libsecp256k1 with Schnorr signatures

neeboo

@neeboo

@albertschr I think the way zilliqa making schnorr is different with Bitcoin-ABC

https://github.com/Zilliqa/Zilliqa-JavaScript-Library/blob/dev/packages/zilliqa-js-crypto/src/schnorr.ts

you can try and make one yourself

@csajedi

@jeremyid is there a zilliqa discord? I didn't know, and it's not on the zilliqa homepage

evesnow91

@evesnow91

@albertschr What language are you using?

I think so far we have JS, Python, Go, Ruby, C#, C++, Swift implementations.

李大狗

@leeduckgo

Thxs.

How do I know the time for a transaction to be complete? I need the transaction time.

@JSSS

guys, how do you like scilla/ zil stack so far? I'm new here

Edison Lim

@edisonljh

I eat scilla for breakfast.

Cameron Sajedi

@csajedi

@JSSS If I'm 100% honest it is rough around the edges. I have great hope, but today none of the sdks I've tried are without hiccups/quirks. Scilla compared to other sc langs (michaelson and solidity) is cumbersome but realistically the benefit of formal verification (eventually) massively outweight the ECMAscript-inspired familiarity of solidity. Looking forward to exceptions and testing out the procedures that were recently added. Now if only the vscode plugin could pair => and transition()... with its corresponding end . Then I'd be much happier

Cameron Sajedi

@csajedi

Can someone send me testnet (or mainnet) zils? the testnet faucet has never worked for me. I tried both old and bech32 addresses
