Kakarot attempts at providing the same value as a standard EVM (e.g. Arbitrum or Polygon): being able to write Solidity smart contracts, deploy them and interact with them - with low gas fees. 

Furthermore, it compares especially to zkSync2.0 or Polygon zkEVM, as it possesses zero-knowledge properties. As Kakarot is written in Cairo, a provable general-purpose programming language that leverages STARKs. 

Currently, Kakarot is deployed as a smart contract on Starknet. The zkEVM's execution context is siloed and embedded in Starknet.  As Starknet is a validity rollup, Kakarot inherits its zero-knowledge properties.

# Is Kakarot equivalent to Arbitrum?

How does Kakarot compare to a more standard L2 such as Arbitrum / Optimism or zkSync 2.0 and Polygon zkEVM?

Is Kakarot equivalent to Arbitrum?

Another question I have is:

**What's easier, adapt the create2 trick in Solidity then transpile or transpile first then adapt in Cairo?**

---

### *From Newton AI:*

*"Create2" is a feature in Solidity, the programming language used to write smart contracts for the Ethereum blockchain. It allows the creation of new contract accounts using a deterministic algorithm, rather than having to send a transaction to create the contract like with the original "create" function. This can be useful in certain situations, such as when creating a contract that is intended to be deployed at a specific address.*

*Transpiling is the process of converting code written in one programming language into another language. This can be useful if a piece of code needs to be run on a platform that only supports a different language, or if it is desired to use a different language's features or syntax.*


Did you change the factory/create2 part (to compute pool addresses)?

How can I connect a predeployed StarkNet account in Starknet-devnet using starknetjs. Is there any difference with connect an existing account (in any network)?

How can I connect a StarkNet account using starknetjs?

```
...
const { available, connect, refresh, disconnect } = useConnectors()

    const connectors = [
      new InjectedConnector({ options: { id: "argentX" } })
    ];

return(
  <button onClick={() => connect(connectors[0])}>
    Connect {connectors[0].id()}
  </button>
)
```
any idea why this code doesnt connect to argentX in brave?

Some questions that could be answered separately.

1. The only way to invoke a contract is using migrations (this applies for both devnet and testnet?)
2. When doing a migration file I receive the “Hint is not whitelisted. This may indicate that this library function cannot be used in StarkNet contracts.” error. For example for this code:

```
%lang starknet

@external
func up() {
    %{
        contract_address = deploy_contract(
             "./build/main.json",
             config={"wait_for_acceptance": True}
        ).contract_address

        invoke(
            contract_address,
            "initialize",
            {"new_authority": 123},
            config={
                "auto_estimate_fee": True,
                "wait_for_acceptance": True,
            }
        )
    %}

    return ();
}
```

Hey everyone, is it possible to use argentx to sign in/authenticate user to a off-chain api/db

What I want to do is store some data off chain for each user(wallet)

I have seen that metamask/etherem has 'personal_sign' rpc method that can be used for something like this

Is there anything like this available in starknet ecosystem?
