# Quickstart

#### Creating a Wallet and Signing Transactions

***

## **Install a Wallet App**

To access full functionality, it is recommended to use one of the wallets listed on the **wallet page**, such as:

* **MetaMask Wallet**
* **Gate**
* **TokenPocket**
* **Trust Wallet**
* **Bitget Wallet**
* **OKX Wallet**

**Note:**\
It is **not recommended** to manually import wallets between **EVM-only** wallet apps and **Cosmos-based** wallet apps using a **mnemonic phrase**. Doing so may generate unexpected wallet addresses due to differences in the coin types.

***

## **Add the** ENI **Network to MetaMask**

* Adding the ENI chain to MetaMask takes just a few clicks.
* Use the button provided to connect your wallet and import the network settings.

***

**Manual Import**

If **automatic connection** fails, you can **manually add** the ENI EVM network by following these steps:

**ENI Mainnet**

* **Network Name:** `ENI Mainnet`
* **RPC URL:** [`https://rpc.eniac.network`](https://rpc.eniac.network/) / [`wss://rpc.eniac.network/ws/`](wss://rpc.eniac.network/ws/) 
* **EVM Chain ID:** `173`
* **Currency Symbol:** `EGAS`
* **Block Explorer URL:** [`https://scan.eniac.network/`](https://scan.eniac.network/) <br>

**ENI Testnet**

* **Network Name:** `ENI Testnet`
* **RPC URL:** [`https://rpc-testnet.eniac.network`](https://rpc-testnet.eniac.network) / [`wss://rpc-testnet.eniac.network/ws/`](wss://rpc-testnet.eniac.network/ws/)
* **EVM Chain ID:** `174`
* **Currency Symbol:** `EGAS`
* **Block Explorer URL:** [`https://scan-testnet.eniac.network/`](https://scan-testnet.eniac.network/)&#x20;

***

## Get ENI Testnet Token

ENI is the native utility token of the ENI Chain, primarily used to pay transaction fees on the network. You can obtain test ENI tokens from a faucet specifically designed for the ENI testnet.

## **Advanced: Wallet Addresses**

Since ENI now supports **two types of wallet addresses**, it is essential to understand their relationship.

* Every account on ENI has a **unique public key**.
* This public key can generate **multiple wallet addresses**, which look different but **function the same**.
* Depending on the application, these addresses might be **interchangeable**.

**Analogy:**\
The difference is like the difference between the **number "2"** and the **word "two"**. They both define the same value but might be used in **different contexts**.

***

## **Types of Addresses**

1. **"hex" Address:**
   * Starts with **0x**.
   * Used for **EVM-based** transactions.
2. **"bech32" Address:**
   * Starts with **"eni"**.
   * Used for EN&#x49;**-native** functionalities.

**Key Insight:**

* Although these addresses look different, they **share the same underlying account**.
* This means any action performed with one address **affects the other** as well.

**Example:**\
If you **deposit funds** to your **EVM address**, you can access those funds using your **ENI address**, and vice versa. This setup ensures **seamless integration** between the **EVM and ENI ecosystems**.

***

#### **Linking EVM and ENI Addresses**

To link your **EVM and ENI addresses**, initiate a transaction **from your EVM address**.

* For example, you can send tokens **to yourself** within your wallet.

***

## **Types of Transactions**

**"Ethereum" Transactions**

* **Signing EVM transactions** is straightforward.
* When an application initiates a transaction, MetaMask will **prompt you to sign**, requesting your approval to proceed.

***

**"ENI-native" Transactions**

* The user experience for signing **ENI-native transactions** is almost the same.
* **Under the hood:**
  * The process is similar to signing EVM transactions.
  * The difference is that the **transaction target** is an **ENI precompiled contract**.
  * Your approval via MetaMask **executes the transaction**.

**Note for Smart Contract Developers:**

* Ensure that the **MetaMask transaction target** is set to a **precompiled contract** on ENI.

***

## **Viewing Tokens**

**ERC20 Tokens**

* The process of viewing **ERC20 tokens** in MetaMask is the **same as on other EVM chains**.
* For tokens that are **not listed automatically**, you will need to **manually import** them into your wallet.

***

**ERC721 NFTs**

* To view **NFTs (ERC721)** in MetaMask, you need to **manually add them**.
