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)

Hi all,

Am planning on starting a mainnet node and running it in a docker container as per these instructions:
https://github.com/eqlabs/pathfinder/#running-with-docker

My question:
I am already running a full Ethereum node on my server. I this case, can I set the  PATHFINDER_ETHEREUM_API_URL parameter to my node's endpoint, i.e. 127.0.0.1:[eth node rpc port]?

Thx.

I am already running a full Ethereum node on my server. Can I set the  PATHFINDER_ETHEREUM_API_URL parameter to my node's endpoint for pathfinder?

I am getting the error above when I use the following line:


`let local (prev : felt) = fibonacci(n-1)`

Cairo Error: Unexpected token Token('LPAR', '('). Expected: identifier.

Another vanilla Cairo question, what are the sorts of references, i.e. ids that can be modified by hints? relatively important to work against an evil prover

presumably not locals or tempvars, but say, implicit references, or the two(?) kinds of let statements (expressions and references)

maybe if there's some documentation i don't know about re: all the id types, relocatable values and so on,

also maybe, is there a pattern that can be used for function pointers?

Hey! I have a contract deployed on Testnet. Let's say its address is `0x1234`.

I want to get its ABI somehow, but I don't have the code of the contract, because it wasn't deployed by me.

I'm using StarkNet.py to interact with StarkNet.

Does anyone know the answer?

How to get the contract ABI using Starknet.Py?

Does Account Abstraction (StarkNet) support bundling multiple operations at once?

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?

There are a bunch of questions about key storage in a new "Account Abstraction" paradigm.
1. Can I recover my key if I lose it?
2. Can I have a key-less wallet?
3. Can I easily create new wallets like in Metamask "Add Account" with only 1 seed phrase?
