seems your old __default__ wallet is broken, probably because its from pre 0.10.0?
I think an older version wallet is causing it. I tryied to deployed a new wallet with
starknet deploy account \
--account=coburn 
and updated my __default__ in 
~/starknet_wallets.json to the new one and it worked for me. 

and

starknet declare --contract contract_compiled.json

following this page from the docs https://starknet.io/docs/hello_starknet/intro.html
I copied the code, compiled it using starknet compile, and when I go to declare it using starknet declare Im getting 
Status code: 500; text: {"code": "StarknetErrorCode.ENTRY_POINT_NOT_FOUND_IN_CONTRACT", "message": "Entry point <address>caed693fa4008dcdb4963b3 not found in contract with class hash <address>975148f6af3e9abddfdc701."}
Any help would be appreciated.

StarknetErrorCode.ENTRY_POINT_NOT_FOUND_IN_CONTRACT error in Cairo. Can anyone help?

Hi guys. What can I do if I've sent transactions from StarkNet to Ethereum L2 -> L1 on mainnet, withdraw was initiated and funds left from Starknet wallet but I don't see any pop up to process L1 deposit? It was 22h ago.

What can I do if I've sent transactions from StarkNet to Ethereum L2 -> L1 on mainnet and transaction got stacked?

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

What are the efficiency gains of direct Cairo vs. transpiling with warp?

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.)

Hey folks, do you know how I could read a felt* from ap?

I want to do something like this:

```rs
    let (hello : felt*) = alloc();
    tempvar world : felt* = hello;
    let world_like : felt* = [ap-1];
```

when I do tempvar world = hello, I ensure I add hello (the pointer) to [ap] and then I increase ap so world_like = [ap-1] should be the same thing than world

But I get this error:

```
Cannot assign an expression of type 'felt' to a reference of type 'felt*'.
    let world_like : felt* = [ap-1];
```

When doing a similar code:

```rust
        let (func_pc: felt*) = get_label_location(storage_var);
        _prepare_call(pedersen_ptr, range_check_ptr, len_inputs, inputs + len_inputs);
        call abs ap[11 - 6 * 2];
```

I get ```
Cannot apply subscript-operator to non-pointer, non-tuple type 'felt'.
        call abs ap[11 - 6 * 2];  // removing alloc_locals by calling ap[11-6*2] ?
```

how I could read a felt* from ap in Cairo lang?

How can I read contract memory with starknetjs?

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 ();
}
```
