wasm-cairo's Issues

Unable to find eth_signature from starknet

On trying to compile the code below,

use core::traits::Into;
use core::array::ArrayTrait;
use core::keccak;
use core::option::OptionTrait;
use core::starknet::SyscallResultTrait;
use starknet::{EthAddress,secp256k1::{secp256k1_new_syscall},eth_signature::public_key_point_to_eth_address};

fn proof(txn_hash: u256, final_hash: u256) {
    let public_key = secp256k1_new_syscall(0x643285cb1513659e8a634ea5d74c2180b2549edce3083e2906aa1c88c918ae4c, 0x6e0086f3d9ff7e443a9d275e0c5e14e3904dd5d4937bad9d7a8e03d6e38b9ef9).unwrap_syscall().unwrap();
    let address = public_key_point_to_eth_address(public_key);
    let mut hash_arr = ArrayTrait::<u256>::new();
    hash_arr.append(address.address.into());
    hash_arr.append(txn_hash);
    let cal_final_hash = keccak::keccak_u256s_be_inputs(hash_arr.span());
    assert(cal_final_hash == final_hash, 'Invalid final hash');
}

fn main() {
    let txn_hash = 0x1;
    let final_hash: u256 = 0xf52437fd0c9b08a5c208b7bfd82ad37120702db8e69608b03242d9d61e3cf2f1;
    proof(txn_hash, final_hash);
}

The following error is showing,

error: Identifier not found.

Backport required changes into main cairo repo

Would it make sense to backport all changes required to compile cairo into wasm into the main repo?
Thanks!

JS -> Cairo -> JS function call

I found 2 projects as example for cairo with wasm, the astro editor and the starklings [https://app.onlydust.com/p/wasm-cairo] . Is the actual state of the cairo wasm is limited to compiling the code on the browser ? The documentation is scarce and both examples are limited. Could you help us to find [or create] an example of a simple cairo function that "talks" with the JS, like 'fn x = x + 1' ? so we can send the number 3 from JS to the cairo wasm module, and get 4 back on the JS UI.

thanks

A landing page.
Intro page, with a playground.
A document page(or link)

Maybe sth like: https://www.dojoengine.org/en/

I created an official site a long time ago: https://delicate-author-279911.framer.app/
However, I am not good at website design, and this site is too old.

You can contact me for any design resource(logo, banner, etc...).
You may create a new repo for this website.
