Hey there, is there an existing Math64x61_pow implementation to compute power of a floating point elevated to an integer power?

edit: looks like there is 🙂

Is there a Cairo Lang implementation to compute power of a floating point?

Why do I need to fund an account before deploying it?

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?

How will work an account abstaction wallet with the key?

Hello everyone. Does anyone happen to know if there's a way to get the block hash in cario? I found out about `get_block_number` and `get_block_timestamp`, but is there something similar for block hash?

How to get the block hash in Cairo lang?

Is there a way/a tool that can automatically generate events for Cairo functions, since pretty much all of my events follow the same format

Cairo Automatic Events

### *From Newton AI*
*OpenZeppelin is a collection of reusable, secure smart contract libraries for Ethereum. It provides a set of Solidity contracts that implement common contract patterns and functions, such as ERC20 token contracts and contracts for managing and securing user accounts. By using OpenZeppelin libraries in your contracts, you can benefit from the security and functionality provided by these pre-written contracts, without having to reimplement them yourself. When transpiling your contracts, the transpiler will include the code from any imported libraries, such as OpenZeppelin, in the final transpiled output.*

Is it possible to transpile contracts that use openzeppelin libraries?

What is the difference between return and ret?
