🌐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
