Troubleshooting
Here are some common issues you may encounter when connecting MetaMask to Arbitrum, and how to resolve them:
❌ MetaMask Fails to Connect
Symptoms:
Network doesn’t appear after clicking “Save”
Connection times out or shows an error
Solutions:
Double-check that all fields (RPC URL, Chain ID, etc.) are entered exactly as shown
Make sure there are no extra spaces or typos in the RPC URL
Try refreshing MetaMask or restarting your browser
❌ Arbitrum Network Added, But Not Visible
Symptoms:
You successfully added Arbitrum, but it’s not showing in the network dropdown
Solutions:
Click the MetaMask icon to re-open it (it may have minimized)
If needed, go to Settings → Networks to verify that Arbitrum is listed
❌ Tokens Don’t Show Up
Symptoms:
ETH is visible, but USDC, USDT, or other tokens are missing
Solutions:
Add the token manually using its contract address
You can find verified addresses on Arbiscan Tokens
❌ Wrong Network Selected
Symptoms:
You're trying to use Arbitrum dApps, but they say “Wrong network”
Solutions:
Make sure “Arbitrum One” is selected in MetaMask
Switch networks manually from the dropdown
❌ Transactions Not Showing on Arbiscan
Symptoms:
You made a transaction but can’t find it on Arbiscan
Solutions:
Confirm you're searching the correct wallet address
Wait a few seconds—block confirmations may be delayed
Double-check that you’re viewing the Arbitrum chain, not Ethereum Mainnet
