In the context of a smart contract wallet, session keys is the concept of delegating signing power for a limited time to a designated entity. This entity is then able to perform actions on behalf of the wallet, in a limited scope (time, money...)

This concept requires an account contract though; so it is easier to implement on chains that have account abstraction.

It is not a specific feature of AA, but one of the many things that can be coded in an account contract.

To answer directly to the OP's question: currently, Account contracts do not support Session Keys out of the box.
You can however add them pretty easily (with some code) and I'm sure we will have a plugin to handle that pretty soon :)

Session keys have been theorized and discussed as a UX improving feature for Account wallets.
The Account Abstraction model surely allows session keys via wallet plugins theoretically. In practice, a few projects have produced PoCs (see briq or cartridge-gg) but no standard implementation exists as of yet.

Does AA support "Session Keys" so I can avoid signing too many transactions when they are redundant?

What is the best way to check if a value is less than another value in a conditional? Say if x > y, then do something

Cairo: Using less than or greater than in conditional

How do I transform data from javascript to Cairo?

In writing my Cairo program I have the following code:


currNumber is a storage variable:


`@storage_var`


`func currNumber() -> (res : felt):`


`end`


And we have code that calls this value and uses the currNum in a subsequent function:


`...` 


 `let currNum = currNumber.read()`


 `let (res) = findSumDigits(currNum, 0)`


`...`


And I am getting the following error:


Expected expression of type 'felt', got '(res : felt)'.


 let (res) = findSumDigits(currNum, 0)


 ^*****^

Hi all! I wanted to know if anyone knows by chance if the Starknet Name Service is working or not?

Is the Starknet Name Service working or not?

Hi,

any idea what this could be caused by? This function is mentioned only once in the whole codebase. I’m trying to do protostar build

```python
Redefinition of '__wrappers__.get_pool_balance.__wrapped_func'.

func get_pool_balance{syscall_ptr : felt*, pedersen_ptr : HashBuiltin*, range_check_ptr}(
```

This error always appears with the first function it encounters that is annotated with either @view or @external

Can be reproduced in the repro-redefinition branch of [https://github.com/CarmineOptions/carmine-protocol.git](https://github.com/CarmineOptions/carmine-protocol.git)

Has anyone seen this error in proto? Redefinition of *`wrappers.*ourfunctionname.__wrapped_func__’`?

Any idea what this could be caused by?

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.
