ERC-4337 Smart Account with zkSync and Ethereum Support

This project implements an ERC-4337 Smart Contract Wallet with support for Ethereum Sepolia, zkSync Sepolia, and Local (Anvil) networks. It includes scripts for deployment, configuration, and sending user operations.

🛠 Prerequisites

• Foundry (for Solidity development)
• Node.js & NPM (if integrating with frontend or scripts)
• OpenZeppelin Contracts
• Account Abstraction (ERC-4337)

🚀 Setup

1. Clone the repository

   git clone https://github.com/Rahber-1/Account-Abstraction.git
   cd Account-Abstraction

2. Install dependencies

   forge install
   forge install OpenZeppelin/openzeppelin-contracts
   forge install eth-infinitism/account-abstraction

3. Compile the contracts

   forge build

🔨 Deployment

Deploy MinimalAccount on Ethereum Sepolia

forge script script/DeployMinimal.s.sol --rpc-url <SEPOLIA_RPC_URL> --private-key <YOUR_PRIVATE_KEY> --broadcast

Deploy MinimalAccount on Local Anvil Network

anvil &
forge script script/DeployMinimal.s.sol --rpc-url http://127.0.0.1:8545 --private-key <ANVIL_PRIVATE_KEY> --broadcast

⚙️ Configuration

The HelperConfig.s.sol file manages network configurations:

• Ethereum Sepolia (chain ID 11155111)
• zkSync Sepolia (chain ID 300)
• Local Anvil (chain ID 31337)

To modify configurations, update getEthSepoliaConfig(), getZksyncSepoliaConfig(), or getAnvilConfig() in HelperConfig.s.sol.

📩 Sending User Operations

Generate and Sign a Packed User Operation

forge script script/SendPackedUserOp.s.sol --rpc-url <NETWORK_RPC> --private-key <YOUR_PRIVATE_KEY>

This will:

1. Generate a signed user operation using the provided sender and calldata.
2. Fetch the correct network entry point from HelperConfig.
3. Sign the operation using the private key.
