Please check your contract functions for deploying. You may be trying to deploy a factory class which may be expecting an argument for a class hash.


Why am I getting the error message `“ArgumentsLengthError: The number of the given arguments (0) do not match what is defined in the ABI (1)”`

I'm getting a lot of error squiggles showing Cairo compilation errors. I wonder how I may turn that off?

What is the technical difference between Solidity -> Cairo transpiler and ZK-EVM Kakarot for StarkNet? Both of them interpret Solidity into Cairo and it can help Solidity developers to use StarkNet. 

But really, how does [Kakarot](https://github.com/sayajin-labs/kakarot) compare to [Nethermind's Warp](https://github.com/NethermindEth/warp)?

Hi guys. What can I do if I've sent transactions from StarkNet to Ethereum L2 -> L1 on mainnet, withdraw was initiated and funds left from Starknet wallet but I don't see any pop up to process L1 deposit? It was 22h ago.

Hey guys,

I am having issue with generating _abi.json file when I use namespace,
Please see example below.

Does someone know solution of how to generate _abi.json file when namespace is used? I really need help 🙏 

This code generates starknet_abi.json

%lang starknet
from starkware.cairo.common.cairo_builtins import HashBuiltin
from starkware.starknet.common.syscalls import get_caller_address

@External
   func store_name{syscall_ptr: felt, pedersen_ptr: HashBuiltin, range_check_ptr}(_count: felt) -> (even : felt) {
      alloc_locals;
      local even;

      let (caller) = get_caller_address();
      if (_count == 2) {
         even = 1;
      }
      return (even=even);
   }
=============================================================
This code does not generates starknet_abi.json (please see use of  namespace)

%lang starknet
from starkware.cairo.common.cairo_builtins import HashBuiltin
from starkware.starknet.common.syscalls import get_caller_address

namespace ToMoon {
@External
   func store_name{syscall_ptr: felt, pedersen_ptr: HashBuiltin, range_check_ptr}(_count: felt) -> (even : felt) {
      alloc_locals;
      local even;

      let (caller) = get_caller_address();
      if (_count == 2) {
         even = 1;
      }
      return (even=even);
   }
}



Issue with generating _abi.json file 

I’m signing a message using 
```
account.signMessage(data) 
```
and immediately verifying the signature with the same data and it’s returning false. I don’t see any issue open on this subject on starknet.js. Is this something you’ve already encountered by any chance?

here’s the code:

```python
const data = { types: proposeTypes, primaryType: 'Propose', domain, message };
const sig = await user.account.signMessage(data);
let res = await user.account.verifyMessage(data, sig); // returns `false`
```

I see that’s the expected way to use signMessage through the tests (https://github.com/0xs34n/starknet.js/blob/b20819424dea824c96ac31e0542733c84d87d441/__tests__/account.test.ts#L125-L126).

So I guess something’s going wrong when it comes to either hashing the data and signing it or hashing the data and verifying the signature?


btw: for those wondering: `verifyMessage` only works if the account is deployed: if you’re doing this with an account not deployed (basically just a keypair) then this won’t work :)

该从该从哪里哪里开始开始学起学起呢呢？？PythonPython嘛嘛？？
