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?

I used the Nethermind Warp Traspiler to translate the Solidity to Cairo successfully, but there was a problem with the test. I don't think there is this `warplib` package, `node_module` there is, but there is no python package. How do I generate python packages?


```python
from warplib.memory import wm_new
from warplib.maths.utils import felt_to_uint256
```

### How to represent / my environment
I used python virtual environment to develop cairo, and then I used this tool to convert solidity to cairo. After compiling, I reported an error and saw that `the warp-related package was not found`.

Warp Traspiler error: the warp-related package was not found. How do I generate python packages?

# I have a Solidity Smart contract like this:
```solidity

 */
contract Storage {

    uint256 number;

    /**

    function store(uint256 num) public {
        number = num;

Hey, I'm using StartkNet.py to make a transaction and it gets rejected. 
How to solve it?

What does this error means? (AssertionError: assert_not_zero failed: 0 = 0.)

Another question I have is:

**What's easier, adapt the create2 trick in Solidity then transpile or transpile first then adapt in Cairo?**

---

### *From Newton AI:*

*"Create2" is a feature in Solidity, the programming language used to write smart contracts for the Ethereum blockchain. It allows the creation of new contract accounts using a deterministic algorithm, rather than having to send a transaction to create the contract like with the original "create" function. This can be useful in certain situations, such as when creating a contract that is intended to be deployed at a specific address.*

*Transpiling is the process of converting code written in one programming language into another language. This can be useful if a piece of code needs to be run on a platform that only supports a different language, or if it is desired to use a different language's features or syntax.*


Did you change the factory/create2 part (to compute pool addresses)?

Trying to install warp with command `yarn global add @nethermindeth/warp`

after successful install I try:
`warp install --verbose`
get this error:

```
zsh: command not found: warp
```


How to install Nethermind's Solidity to Cairo transpiler without an error "command not found: warp"?

Is there a way to call another function or contract and 'expect it to fail' without failing the whole transaction?
