# EtherLite Crypto Wallet

## Project Overview

EtherLite is a cryptocurrency wallet developed from scratch, **without the use of any external libraries**. It provides a robust and user-friendly interface for managing Ethereum transactions and accounts.

## Key Features

### Wallet Management

- Ability to **create and import existing wallets** using private keys or mnemonic phrases.

- Secure storage of passwords using the local storage and secure **encryption mechanisms**.

### Blockchain Interaction

- Implemented **node and data retrieval functions** for Ethereum interaction.

- Key pair generation and **address derivation** from public keys.

- **Mnemonic generation** using BIP-39 standards.

### Transaction Handling

- Raw transaction **creation, signing, and sending** executed manually without using external libraries.

- Functions for managing **account nonces** and estimating **gas requirements**.

### User Interface

- Developed a main wallet interface, including:

  - **Transaction creation and confirmation modals.**

  - **Portfolio screen** displaying live balance tracking.

- **Network selection dropdown** to switch between Ethereum networks seamlessly.

### Usability Enhancements

- Modals for sending and receiving transactions, with **clipboard copy functionality** for addresses.

- Custom RPC URL input for **additional network management**.

## Tech Stack

### Frontend

- **React**, Material UI, Framer Motion, and other libraries.

### Blockchain

- **BIP-39** for mnemonic generation.

- Crypto libraries like **Ethereumjs-util**.

### Cryptography

- Custom implementations for:

  - **Key pair generation.**

  - **Transaction signing.**

### Networks Supported

- **ETH Sepolia**

- **ETH Arbitrum Sepolia**

- **Polygon zkEVM**

- **Polygon amoy**

- **ETH Holesky**  

### Blockchain Node

- Powered by **Alchemy**.
