• Transaction History: View transaction history for ETH and ERC-20 token transfers.
• Secure: Uses best practices for private key management and transaction signing.

Technologies Used

• Flutter: A cross-platform mobile development framework used for building the app.
• Dart: Programming language used for building the app’s logic and UI.
• Web3: Used for interacting with the Ethereum blockchain for transactions and querying balances.
• Provider: State management solution for handling app data and user interactions.
• BIP32/BIP44: Standard for generating hierarchical deterministic wallets.
• Flutter Secure Storage: For securely storing private keys and sensitive data.

Requirements

Before you begin, make sure you have the following:

• Flutter SDK: You must have Flutter 3.0 or later installed on your machine.
• Ethereum Wallet: You can use a wallet like MetaMask or any Ethereum wallet that allows you to export your private key or mnemonic phrase.
• Internet Connection: Required for sending transactions and fetching blockchain data.

Installation

Follow these steps to run the ChibiWallet app locally:

1. Clone the repository:

git clone https://github.com/your-username/ChibiWallet.git

Usage

Once the app is installed, you can perform the following tasks:

1. Creating or Importing a Wallet

Launch the app and either create a new wallet or import an existing wallet using a private key or mnemonic phrase. The wallet will be securely stored, and you can access it whenever you open the app.

2. Sending Ethereum or ERC-20 Tokens

Go to the Send screen, select whether you want to send ETH or an ERC-20 token, enter the recipient's address, amount, and confirm the transaction. Ensure you have sufficient balance for the transaction, including gas fees for ETH transactions.

3. Viewing Your Balance

On the Home screen, you can view your current ETH balance and the balance of any supported ERC-20 tokens.

4. Backup & Restore Wallet

In the Settings menu, you can back up your wallet to a secure location using a mnemonic phrase or private key. You can also restore your wallet by entering the backup phrase or key.
