You've heard of StarkNet and are currently trying to start building on it, however... Cairo sounds tough, and you're not sure where to start. Here is a compilation of the best resources to get you started with Cairo. 👇👇

Calling all Starknet devs! Get ready to unleash your inner ERC20-creating superhero with the release of Cairo 1.0-alpha.2! With new features like dictionaries, events, and mapping storage variables, the sky's the limit (but hopefully not your gas fees) starkware.medium.com/cairo-1-0-alph

We’re on a mission to make building on

Creating Upgradable Smart Contracts on StarkNet

with Cairo easier! If you’re just getting started, you’re probably in search of tools that could go a long way in making your journey a lot smoother… In this thread, we’ll tell you about Protostar, Argent X and

8/ For a more in-depth dive and hands-on practice on Upgradeable contracts, make reference to the links below: medium.com/starknet-edu/c github.com/Darlington02/m

TL;DR; To make a smart contract upgradable in preparation for Regenesis you’ll need to turn your constructor function into an initializer…

7/ The proxy knows where to delegate the call by storing the class hash of the declared implementation. Thanks to the team at

@OpenZeppelin

, we already have a good template to follow. You can find their contracts and presets here: github.com/OpenZeppelin/c

6/ When a call is made to the proxy contract, it forwards them to another contract by exposing the __default__ method. This method is a fallback method that redirects a function call and associated calldata to the implementation contract.

5/ The Proxy pattern requires two smart contracts, the Proxy, and the Implementation The Proxy serves as the entry point and also holds the contract storage, whilst the Implementation contains the code/logic of your dApp.

4/ Note that there’s a difference between a contract class and a contract instance on StarkNet A contract class is gotten when a contract is declared, and just contains the contract’s code with no storage, while a contract instance is deployed and has access to storage

3/ The Proxy pattern is a mechanism for changing the code of a smart contract while preserving its internal state. At the heart of it is the syscall library_call that allows you to call any smart contract class while keeping the caller as the context for storage

2/ An Upgradeable contract is one which allows you to change the underlying logic of your smart contract, without necessarily altering the contract address of your dApp This is done by separating your contracts into a Proxy and implementation, also known as the Proxy pattern

1/ If you are planning to deploy a smart contract today on mainnet

@StarkNet

and you want to prevent having to migrate users and assets (hard fork) when Regenesis happens, you’ll need to make your smart contract upgradable.

With Regenesis at hand, it’s become a necessity to understand how Upgradeable contracts work, in order to successfully migrate existing contracts to Cairo v1.0 Here's what you need to know 🧵👇

Account Abstraction is key to improving the user experience and security of self-custodial crypto wallets. By removing the reliance on private keys and making wallets more programmable, we can finally onboard millions of mainstream users without the fear of getting hacked /1
