What are function argument types in starknet.js?

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 :)

Hi team. How can I use start_prank with deploy_contract? Since get_caller_address() works in constructor now, I need a way in protostar to set caller address without having contract address. May be a 'caller' argument in deploy_contract cheatcode works best.

How can I use start_prank with deploy_contract? 

When running my python tests I get:


 NotImplementedError: Invoking through an account contract is not supported yet, please use execute() instead.


 Has anyone seen this problem and know of a solution?

is there anything wrong with the testnet? why is it so slow now?

### *From Newton AI*
*"Assembly" is a low-level language that is used to write smart contracts for the Ethereum Virtual Machine (EVM). It is similar to machine code, which is the code that is run directly on a computer's central processing unit (CPU). Assembly is often used in Solidity contracts to perform complex tasks or to optimize the performance of the contract.*

*If a Solidity contract contains assembly code, it is important to be careful when working with it, as it can be difficult to read and understand. Additionally, certain assembly instructions, known as "special EVM calls," can have unintended consequences if not used correctly. For example, some special EVM calls can cause a contract to consume an excessive amount of gas, which can make it more expensive for users to interact with the contract.*

*It is generally recommended to avoid using assembly in Solidity contracts if possible, as it can make the contract more difficult to understand and maintain. If you do need to use assembly, it is important to thoroughly test and debug the contract to ensure that it functions as intended.*

What if my solidity contract contains Assembly or special EVM calls ?

Ahoy Caironauts,

  How can I define two functions with the same name but not the same arguments, e.g, 

- `func test()`
- `func test(param: Uint256)`

It is possible in Solidity and I'm trying to find the Cairo equivalent.
