this worked:



```
let (local balance) = IERC20.balanceOf(contract_address=asset, account=owner);
let bal = balance.low;
%{ print("current owner balance: ", ids.bal) %}
```

Interestingly, reflect still didn’t work on `bal`.

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)

Hey,
As each storage value is by default initialized to 0, does writing it to zero actually do something? Does it use storage in layer 1 with value 0? Or does it just do nothing?
Should I check that the value I want to write is different than 0 before writing it otherwise I will waste storage?

The same idea: does writing a storage value to 0 free storage on l1

Does writing it to zero actually do something?


I built a module with Cairo language and I would like to unit test it. The contract is pretty simple : it manages a list of authorized addresses and provide some "modifier" functions to help.


I have taken the sample unit testing code from the documentation but nothing is referring about sending an account address to a function with python.


How should I proceed ?


Thanks in advance

Hi, 
Would anyone have a link or know how fast blocks would be generated on StarkNet after Regenesis ?
I am working on a project where I mint an NFT which can be burnt to mint other NFTs. Hence, I'd like to know how much minimum time there will be between these two mints transactions.
