No, not yet. We have an expansive test suite to check the behaviour of the transpiled contracts. Warp is tested with the semantic test as solc and there are additional handwritten behaviour tests.

Have there been any security issues reported on the Cairo code generated from warp so far?

I use `ec.getKeyPair("copy paste from argent x")` to initialize the account however i get the response is invalid, with respect to the public key

Invalid response while using `ec.getKeyPair("copy


I've written a couple contracts for L1 (Ethereum) and L2 (Starknet) and have them communicate [here](https://www.cairo-lang.org/docs/hello_starknet/l1l2.html).


I can see that L1 sent the message I'm expecting, see [this TX on etherscan](https://goerli.etherscan.io/tx/0x28f3c1021672431d81b34cc141b49a927ae9c989b1521f12b971c45e9717b1f6). The last message in there however never executed on my L2 contract. I'm trying to figure out whether the L2 Sequencer has invoked the handler function of my contract and if so, whether/how it failed.


Does anyone here know how to find the TX that handles the invoke on L2? Or any other ideas/tools that would help figuring out why the l1\_handler never executed/failed?

Hi, I'm using pytest for testing cairo contract. I found that a simple starknet setup and initial call for contract cost 34 seconds. Is there a way to accelerate test?

upd: yes, [this works](https://www.notion.so/Hi-I-m-using-pytest-for-testing-cairo-contract-I-found-that-a-simple-starknet-setup-and-initial-ca-db2282fc02f2463aadaf63eac655df6f). but I found that compiling contract cost 7s and deploying contract cost 25s. These two operations are the most time-consuming

 Is there a way to accelerate pytest for cairo contract?

I try to execute a code with `get_balance_sync` method:
![get_balance_sync Cairo StarknetPy code sample](https://res.cloudinary.com/varga/image/upload/c_pad,b_auto:predominant,fl_preserve_transparency/v1670921600/code_image_spbt0g.jpg)

However, I got this error:

```
starknet_py.net.client_errors.ClientError: Client failed with code 500: {"code": "StarknetErrorCode.ENTRY_POINT_NOT_FOUND_IN_CONTRACT", "message": "Error at pc=0:10:\nGot an exception while executing a hint.\nCairo traceback (most recent call last):\nUnknown location (pc=0:228)\nUnknown location (pc=0:214)\n\nError in the called contract (0x7f81ea93daf9c49494e3131b95646c3a8df5d97d151cc6484d49eaebe3e3d0a):\nEntry point 0x2e4263afad30923c891518314c3c95dbe830a16874e8abc5777a9a20b54c76e not found in contract with class hash 0x3ae692aaf1ded26a0b58cf42490f757563850acea887ed57b4894fee8279063."}
```

Can you help me to resolve this?

This isn't a starknet question, but raw cairo. is it possible to use a pointer reference like let, and set it to a pointer with a hint, without doing a memory allocation?

looks like the answer is yes, but you do need to assign a reference when you declare a pointer reference with let, but that doesn't alter the memory

e.g.

```python
let s : felt* = cast(ap, felt*)
{
	ids.s = some_other_reference
}
```

the `cast(ap, felt*)` does nothing, just satisfies the compiler by having something on the rhs of a let

a pointer with a hint, without doing a memory allocation

In the following function I am presented with the following error, even though my code does not make it to this function. What am I doing wrong?


`func fill_in_row{output_ptr: felt*}(row_idx : felt, row_size : felt, curr_row : felt*) {` 


 `if (row_idx == row_size-2) {`


 `return ();`


 `}`


 `let val : felt = curr_row[row_idx-1] + curr_row[row_idx];`


 `serialize_word(val);`


 `curr_row[row_idx+1] = val;`


 `return fill_in_row(row_idx+1, row_size, curr_row);`


`}`


Error: code:80:5: While expanding the reference 'curr_row' in:


 curr_row[row_idx+1] = val;


 ^******^


code:72:73: Expected a register. Found: [fp + (-4)].
