How to import and possibly expand on the Account contract?

[lsbyerley]

Hey all.. new to the cairo/starknet ecosystem. Coming from solidity, I've been able to import a contract, expand on it, and then compile the contract.

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

contract Token is ERC721 {
    // constructor and other added functions
}

What would be the cairo equivalent to this? Let's say I want to import the openzeppelin/account/Account.cairo contract, expand on it and compile it. I can't seem to find an example of this. Am i thinking of this whole process incorrectly? The readme says to run nile compile .. but that looks into the contract directory. So i guess i assumed i should create a contract in the contracts directory that imports the cairo account contract (assuming i want to compile an account contract).

I have this repo cloned, with a python env and nile setup. Just wondering how to proceed from there

Hello! There are two answers to your question:

• The library is still in experimentation phase and the readme warns users to use at their own risk, that's why there is no official release/easy way to install it yet. expect one really soon
• Since there's no language-level inheritance/mixin in Cairo, our contracts follow our own contract extensibility pattern™️.

Thank you for the information @martriay! I'll just use the base account contract for now!
