Pathfinder don’t represent a specific account on StarkNet and this is therefore not possible. If you want your wallet to use your specific pathfinder instance for data then you will have to ask your wallet provider if / how that is possible.

How do I connect my wallet to my Pathfinder node?

How can I write contract memory with starknetjs?

hi, i used the starkgate bridge from stark to eth one hour ago. Withdrawal has not occurred yet. How many hours does the process take? My tx hash is: <address>cfa0c02d013658804505506

How many time does it take for stark to eth starkgate bridge process?

Is it possible to use Solidity's abi.encode and abi.decode in Cairo? Our periphery contract uses these 2 functions in EVM to send a tx to the core contracts, and then if a condition is met the core contract calls back the router like so:

router -> core -> router

An example of this can be found here: 

**router:**
https://github.com/CygnusDAO/periphery/blob/main/contracts/cygnus-periphery/CygnusAltairX.sol#L758

**core:**
https://github.com/CygnusDAO/core/blob/main/contracts/cygnus-core/CygnusBorrow.sol#L145

Thanks!

Abi.encode and Abi.decode in Cairo?

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 large can addresses be in Cairo?

Does anyone know how I can create an array and populate it in the python hint?
Basically something like


```cairo
let (my_array: felt*) = alloc()
%{
  ids.my_array = [1, 2, 3]
%}
```


How can I create an array and populate it in the hint Cairo lang/Protostar?

For an array in Cairo, since there is no inherent structure, removing an item from an array means all of the other items after the removed item must be moved, since this is on the blockchain that can be extremely costly. What is the best way to handle this? Should the removed item just be replaced with an empty placeholder? What is the right way to handle this?
