Kakarot zkEVM is a smart contract, deployed on Starknet, the Ethereum L2. It provides a zkEVM encapsulated inside a smart contract.

# I have a Solidity Smart contract like this:
```solidity
// SPDX-License-Identifier: GPL-3.0

pragma solidity >=0.7.0 <0.9.0;

/**
 * @title Storage
 * @dev Store & retrieve value in a variable
 */
contract Storage {

    uint256 number;

    /**
     * @dev Store value in variable
     * @param num value to store
     */
    function store(uint256 num) public {
        number = num;
    }

    /**
     * @dev Return value 
     * @return value of 'number'
     */
    function retrieve() public view returns (uint256){
        return number;
    }
}

What resources are required to run a Pathfinder node?

Hey, I'm using StartkNet.py to make a transaction and it gets rejected. 
How to solve it?

What does this error means? (AssertionError: assert_not_zero failed: 0 = 0.)

Hello, Do I understand this correctly: Pathfinder JSON-RPC V0.1.0 does not support InvokeTXNV1 yet, right? At least, I do not `nonce` in `add_invoke_transaction`.

Do you plan to add it in JSON-RPC V0.1.0 like devnet (not being compliant to the spec) or will you introduce it with JSON-RPC V0.2.0?

_This question was originally posted on [StarkNet Discord](https://www.newton.so/view?tags=discord)_

Can anyone explain Pathfinder JSON-RPC InvokeTXNV1?

Why am I getting an `account __execute__` error message `ape_starknet.exceptions.StarknetProviderError: Can only send invoke transaction to an account execute method`?

### *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.*
