How can I get ETH for the test net in StarkNet?

I’m just getting started and having problems installing the [Cairo](https://github.com/ApeWorX/ape-cairo) and [Starknet](https://github.com/ApeWorX/ape-starknet) plugins using the ape console. Why are the plugins not installed properly?

How can I send a Uint256 amount of ERC20 tokens from L1 to starknet?
I have "amount" as a uint256 on L1 but how should I build my payload for "`sendMessageToL2`" to match the Uint256 format of Cairo?

I am trying to deploy my contract using this tutorial
[https://medium.com/starknet-edu/deploying-to-starknet-with-the-universal-deployer-contract-c6de07092bfb](https://medium.com/starknet-edu/deploying-to-starknet-with-the-universal-deployer-contract-c6de07092bfb)
But as I follow the steps, I got an error at the contract declaration step: `Unitialized Contract`

 I usually use truffle and solc is installed locally but not globally. Should I installed it? Is it worth adding in the readme?

 How do I check that my Solidity compiler version is >= 0.8.0 ?

is there an example of migration scripts somewhere ?

Is there an example of migration scripts somewhere [Cairo/StarkNet]?

Hey guys, has anyone had `get_caller_address` problems in devnet ? I feel like it's returning address 0 when it shouldn't so I made this small contract to test it

```%lang starknet

from starkware.cairo.common.cairo_builtins import HashBuiltin

from starkware.starknet.common.syscalls import (get_caller_address)


func caller_addr() -> (res: felt) {
}



func fn_to_be_called{syscall_ptr: felt*, pedersen_ptr: HashBuiltin*, range_check_ptr: felt}() {
    let (caller) = get_caller_address();
    caller_addr.write(caller);    

    return ();
}


func get_caller_addr{syscall_ptr: felt*, pedersen_ptr: HashBuiltin*, range_check_ptr: felt}() -> (caller_addr: felt) {
    let (caller) = caller_addr.read();

    return (caller_addr=caller);
}```

and indeed `get_caller_addr` return address 0 after I called `fn_to_be_called` in the devnet. This is causing some problems in more complex contracts of course. Is it just me ?

Hi! I like writing my Cairo code in vim. However, I don't like that Cairo lang code has no auto-format and syntax highlighting (see screenshot):

I'm looking for a plugin to write Cairo contracts on Starknet in vim with all pretty formatting. Can you recommend any and how to install it as well?
