# Setup & Configure RPCs & Networks

### 1️⃣ What is RPC and why is it important?

**RPC (Remote Procedure Call)** is the gateway that connects your crypto wallet (MetaMask, Rabby, OKX Wallet, Pulse Wallet, IM Wallet…) to a blockchain (PulseChain, Ethereum, BSC, Base, Arbitrum…).

Every time you:

* Open your wallet
* Check your balance
* Swap tokens on Liberty Swap Finance
* Sign or send a transaction

Your wallet sends requests to the blockchain through an **RPC server**.

If the RPC is slow, overloaded, or broken, your wallet will appear to malfunction — even though your assets are still safely stored on-chain.

### 2️⃣ When do you need to change RPC?

You should consider changing your RPC when you experience any of the following:

#### ❌ Your token balance shows as zero

Even though you know the funds are there.

#### ❌ Transactions stay pending forever

Or get stuck on “Confirming…”

#### ❌ Liberty Swap Finance does not load correctly

Pools, prices, or swap functions fail to display.

#### ❌ Errors such as

“Failed to fetch”, “RPC error”, “Network error”

#### ❌ The blockchain feels slow or unresponsive

The default RPC is congested or temporarily down.

### 3️⃣ The solution: Change or add another RPC

An RPC is just a **connection server**.\
Changing RPC means:

* You are switching to another gateway to the same blockchain
* Your wallet, funds, and private keys remain unchanged
* Security is not affected

Think of it like:

> If a website is slow, you switch to a different server or DNS to access it faster.

## 📘 HOW TO CHANGE OR ADD A CUSTOM RPC

### 4️⃣ How to add or change RPC in your wallet

This works for:\
**MetaMask, Rabby, OKX Wallet, IM Wallet, Pulse Wallet, Trust Wallet (EVM mode)**

#### Step 1

Open your wallet → Click the **Network Selector** (Ethereum, BSC, Arbitrum, etc.)

#### Step 2

Select **“Add Network”** or **“Custom RPC”**

#### Step 3

Fill in the following fields:

| Field              | Description          |
| ------------------ | -------------------- |
| Network Name       | Display name         |
| RPC URL            | Node endpoint        |
| Chain ID           | Blockchain ID        |
| Currency Symbol    | Native coin          |
| Block Explorer URL | Transaction explorer |

#### Step 4

Click **Save** → Switch to the new network → Done

### 5️⃣ Advanced tip: Use multiple RPCs for stability

Some wallets (Rabby, IM Wallet, Pulse Wallet) allow you to add multiple RPC URLs for the same network.

This enables:

* Automatic failover if one RPC goes down
* Faster data loading
* More reliable swaps and transactions

### 6️⃣ Security notes

✔ RPC servers cannot access or steal your funds\
✔ They only read blockchain data and relay transactions\
❗ However, malicious RPCs could:

* Show incorrect balances
* Redirect you to fake networks

Always use RPCs from:

* Official blockchain websites
* Project documentation
