In this tutorial we'll deploy a simple smart contract in ZKsync. Then we'll deploy another smart contract in L1 and send transactions that update the state of the contract in ZKsync. We'll use the Mailbox

In this tutorial, you will get familiar with the ZK Inception CLI. You will create a local Elastic Chain ecosystem and deploy a contract to a ZK chain. Next, you will create a new ZK chain that uses a custom ERC20 base token.

This tutorial will guide you through the process of building a smart contract account that has a daily spend limit. We'll create a factory contract that deploys new smart accounts and configure the account limit and test it works as expected

This tutorial will guide you through the process of building a frontend that interacts with smart contracts on ZKsync. The frontend will enable gasless transactions for users that hold a specific NFT thanks to a paymaster.

This tutorial will guide you through the process of building a paymaster that accepts a fixed amount of any ERC20 token in exchange for transaction fees. We'll use it to interact with a smart contract and pay the fees with an ERC20 token.

In this tutorial, you will set up a local ZKsync Era environment using era_test_node, leverage Foundry's cast tool to interact with contracts, and perform token swaps on Uniswap. You will learn how to check balances, deposit ETH for WETH, transfer WETH, and swap tokens using Uniswap's Swap Router.

This tutorial will guide you through the process of building a smart contract account that requires two ECDSA signatures to execute transactions. We'll create a factory contract that deploys new smart accounts and a multisig smart account that can only execute transactions if two signatures are provided.
