This repository contains the implementation of CresoWallet, a smart contract designed for ERC-4337 account abstraction. ERC-4337 introduces a new standard for account abstraction in Ethereum, enabling more flexible account management and transaction handling without requiring changes to the Ethereum protocol.
ERC-4337 is a proposal for account abstraction that allows for the creation of user accounts as smart contracts. These accounts can define custom rules for transaction validation, enabling features like recovery mechanisms, batched transactions, and more, all managed at the smart contract level. This proposal does not require any changes to the underlying Ethereum protocol and works within the existing framework.
CresoWallet is a smart contract implementation that leverages the ERC-4337 standard. It includes features such as:
-
Guardian-based recovery process.
-
Batched transaction execution.
-
Customizable transaction validation logic.
-
Enhanced security and user control over their accounts.
Ensure you have Node.js and npm installed. This project uses Hardhat, a popular development environment for Ethereum software.
- Clone the repository:
git clone https://github.com/CresoWallet/creso-smart-wallet
cd creso-smart-wallet- Install dependencies:
npm install
- Running Tests
Run the tests to ensure everything is set up correctly:
npx hardhat test
- Deployment
To deploy CresoWallet using Hardhat:
Create a .env file in the root directory and set up your Ethereum network and private key:
env
INFURA_API_KEY=your_infura_api_key
PRIVATE_KEY=your_private_keyRun the deployment script:
npx hardhat run scripts/deploy.js --network your_networkReplace your_network with the Ethereum network you wish to deploy to (e.g., mainnet, rinkeby, ropsten).
