## Account Abstraction Lesson 17: Live Demo on Arbitrum The time has come for us to deploy our code base. Let's run our deploy script - `DeployMinimal`. --- > ❗ **IMPORTANT** This demo is run on a real network, which requires real money. It's recommended just to follow along with the video, and focus more on the code and learning how to deploy to the mainnet. > ❗ **NOTE** The hardcoded values are from the instructor. Your actual values may vary. As always, you can see up-to-date code in the repo. 🔥🔥🔥[Cyfrin Minimal Account Abstraction Repo](https://github.com/Cyfrin/minimal-account-abstraction)🔥🔥🔥 --- Run the following in your terminal. ```js forge script script/DeployMinimal.s.sol --rpc-url $ARBITRUM_RPC_URL --account smallmoney --broadcast --verify ``` We forgot to complete the `run` function in our `SendPackedUserOp` script. Let's do that now. --- **<span style="color:red">SendPackedUserOp.s.sol</span>** ```js // Add these imports import {IERC20} from "@openzeppelin/contracts/token/ERC20/IERC20.sol"; import {MinimalAccount} from "src/ethereum/MinimalAccount.sol"; // run function function run() public { // Setup HelperConfig helperConfig = new HelperConfig(); address dest = 0xaf88d065e77c8cC2239327C5EDb3A432268e5831; // Arbitrum mainnet USDC address uint256 value = 0; bytes memory functionData = abi.encodeWithSelector( IERC20.approve.selector, 0x9EA9b0cc1919def1A3CfAEF4F7A66eE3c36F86fC, 1e18 ); bytes memory executeCalldata = abi.encodeWithSelector( MinimalAccount.execute.selector, dest, value, functionData ); PackedUserOperation memory userOp = generateSignedUserOperation( executeCalldata, helperConfig.getConfig(), 0x03Ad95a54f02A40180D45D76789C448024145aaF ); PackedUserOperation[] memory ops = new PackedUserOperation[](1); ops[0] = userOp; // Send transaction vm.startBroadcast(); IEntryPoint(helperConfig.getConfig().entryPoint).handleOps( ops, payable(helperConfig.getConfig().account) ); vm.stopBroadcast(); } ``` --- > ❗ **NOTE** HelperConfig for arbitrum has already been set up off screen. --- Now that we've got it set up, let's deploy our `SendPackedUserOp.s.sol` to Arbitrum. Run the following in your terminal. ```js forge script script/SendPackedUserOp.s.sol --rpc-url $ARBITRUM_RPC_URL --account smallmoney --broadcast -vvv ``` Congratulations! We've successfully made our first **account abstraction user operation call!** When you are ready, move on to the next lesson.
