Hi sorry for this, since StarkNet is still at alpha stage, so the team'll improve the performance gradually. Soon the team will introduce the first version of parallelization to our Sequencer (few weeks) which should improve the TPS, in V0.10.1. And they're are also working on using LambdaClass rust implementation of cairo https://github.com/lambdaclass/cairo-rs to our Sequencer. This will also improve the TPS, but it will take at least 1 month. Thanks for your understanding!

Why I randomly get `HttpError: Bad Gateway` from starknet js?

What resources are required to run a Pathfinder node?

Hey there! 

I am using the Oz Nile framework for smart contract development on Starknet. More specifically, I am testing the proxy upgrade feature, but my tests fail with the error message TypeError: int() can't convert non-string with explicit base. This happens when nile.signer tries to sign a transaction. Here's the snippet in the stack trace below. 

```
def sign_transaction(self, sender, calls, nonce, max_fee):
        """Sign a transaction for an Account."""
        (call_array, calldata) = from_call_to_call_array(calls)
        message_hash = get_transaction_hash(
>           int(sender, 16), call_array, calldata, nonce, int(max_fee)
        )
```

Some relevant info:
cairo-lang==0.10.0
cairo-nile==0.8.2
openzeppelin-cairo-contracts==0.4.0b
pytest==7.1.2
python=3.9

Cairo/Nile: Testing the proxy upgrade feature, but my tests fail with the error message TypeError: int() can't convert non-string with explicit base.

### *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 ?

I’m just getting started and having problems installing the [Cairo](https://github.com/ApeWorX/ape-cairo) and [Starknet](https://github.com/ApeWorX/ape-starknet) plugins using the ape console. Why are the plugins not installed properly?

Looking to call the approve and transfer functions for an erc-20 in the same transaction. Thoughts on how to do this?
