I suspect it will be similar to cairo-lang's CLI where you provide first the length of the array (baseUri_len) and then all the felts that represent 31 characters chunks of the baseUri. Those felts have to be passed in order,does it make sense?

this article might help you understand how would you do that with cairo-lang, nile is a wrapper for cairo-lang so it should work the same way: [https://david-barreto.com/starknet-erc721-workshop-exercise-7/](https://david-barreto.com/starknet-erc721-workshop-exercise-7/)

I'm trying to use Nile (StarkNet).
I send this function call : 

```cairo
func setBaseURI{pedersen_ptr: HashBuiltin*, syscall_ptr: felt*, range_check_ptr}(
    baseUri_len: felt, baseUri: felt*
)
```

The only thing that would get processed is 

```
nile send account mycontract setBaseURI 3 1 1 1
```

but I don't think that's the right way. How do you pass an array of felt to call with Nile?

How can I pass an array of felt to call with Nile in StarkNet?

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)?

does cross-chain bridge produce its own block? or it only verify the blocks from A/B chain?

Everyone knows that secure code is essential. Can someone explain what is reentrancy?
I am curious about the reentrancy attack in StarkNet – is it a problem in Cairo Language and how to protect my smart contract from this attack?

How to protect my contract from reentrancy in Cairo Language / StarkNet?

I'm implementing the new version and had a couple Q's:

- Is `useStarknetExecute` now the only transaction method (for multi and single calls).
- Do we update the transaction manager on our end? I seem to remember `useStarknetInvoke` also update this automatically

Questions about useStarknetExecute. Do we update the transaction manager on our end? [StarkNet/Cairo]

I'm currently trying to transpile an ERC 721 contract I have that uses openzeppelin libraries, is that possible?


What kind of efficiency gains can one expect from writing the contracts directly in Cairo as opposed to transpiling with warp?
