I got an error while deploying:
`{"code": "StarknetErrorCode.DEPRECATED_TRANSACTION", "message": "Deploy transaction is no longer supported."}`

Umm, cairo playground does not support deploying contracts anymore

What is the most user-friendly way to deploy contracts on starknet for now?

StarknetErrorCode.DEPRECATED_TRANSACTION while deploying StarkNet contract

I'm aware of starknet having a common--and unsafe--keccak library. Either way, I was wondering if there's a way to mimic the behavior of solidity's 
```
keccak256(abi.encode(parameters))
```
Thank you very much.

Is there a Cairo equivalent to Keccak256(abi.encode(parameters))?

Does anyone know how to print a uint256 in protostar tests?

```
let (local balance) = IERC20.balanceOf(asset, owner);
%{
    balance = reflect.balance.get()
    print("current owner balance: ", balance)
%}
```

this errors out: [https://github.com/software-mansion/protostar/issues/1129](https://github.com/software-mansion/protostar/issues/1129)

hi,guys

QUESTION, where can i get test tokens?

_This question was originally posted on [StarkNet Discord](https://www.newton.so/view?tags=discord)_

Where can i get test tokens in StarkNet?

I’m signing a message using 
```
account.signMessage(data) 
```
and immediately verifying the signature with the same data and it’s returning false. I don’t see any issue open on this subject on starknet.js. Is this something you’ve already encountered by any chance?

here’s the code:

```python
const data = { types: proposeTypes, primaryType: 'Propose', domain, message };
const sig = await user.account.signMessage(data);
let res = await user.account.verifyMessage(data, sig); // returns `false`
```

I see that’s the expected way to use signMessage through the tests (https://github.com/0xs34n/starknet.js/blob/b20819424dea824c96ac31e0542733c84d87d441/__tests__/account.test.ts#L125-L126).

So I guess something’s going wrong when it comes to either hashing the data and signing it or hashing the data and verifying the signature?


btw: for those wondering: `verifyMessage` only works if the account is deployed: if you’re doing this with an account not deployed (basically just a keypair) then this won’t work :)

signing a message using account.signMessage(data) | starknet.js

I have the following code:


`@external`


`func updateCurrNum{syscall_ptr : felt*, pedersen_ptr : HashBuiltin*, range_check_ptr}(updatedNum : felt):`


 `let (isOwner) = isOwner()`


 `assert isOwner = 1`


`...`


And I am getting this error: 


Unexpected '.' after '__main__.updateCurrNum.isOwner' which is future.


 let (isOwner) = isOwner()


 ^*****^


What am I doing wrong?

How can I find the current contract's address in Cairo? Is there an equivalent to `address(this)` from Solidity?

Cairo: How do I find the current contract's address?

Hey, the docs always use `await` before methods, but when I try to run those scripts I get an error. 

Anyone could help?
