🌐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:
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

⚠ Solana does not use EVM-style RPCs. You must use a Solana-compatible wallet such as Phantom, Solflare, Backpack, or OKX (Solana mode).

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
