Having trouble connecting your wallet to PredictBase? Here’s a quick guide to help you fix common issues and get back to predicting in no time.
Symptoms:
“Connect Wallet” does nothing
Site doesn't recognize MetaMask or Coinbase Wallet
Solutions:
Ensure your wallet extension (like MetaMask) is installed and unlocked
Refresh the page and try again
Disable browser extensions like Brave Shield, ad blockers, or privacy blockers
Try using https://predictbase.app in Chrome or Brave
Symptoms:
You’re on Ethereum or another chain, and PredictBase doesn’t work properly
Solutions:
Open your wallet (MetaMask, etc.)
Switch to Base Mainnet
If Base isn’t listed, add it manually using:
Network Name: Base Mainnet
New RPC URL: https://mainnet.base.org
Chain ID: 8453
Currency Symbol: ETH
Block Explorer URL: https://basescan.org
Most dApps (including PredictBase) will also auto-prompt the network switch.
Symptoms:
QR code doesn’t scan or connect
Wallet app stuck on "Pending"
Solutions:
Refresh the page and try reconnecting
Use a different wallet app (like MetaMask Mobile or Trust Wallet)
Make sure your mobile device is on the same WiFi network as your desktop (for better pairing)
Symptoms:
Approve/Bet buttons show error
Wallet says "transaction failed" or "insufficient funds"
Solutions:
Make sure you have enough USDC for the bet
Also check you have ETH on Base to cover gas fees
Reconnect your wallet and refresh the browser
Try these:
Disconnect wallet → refresh site → reconnect again
Clear your browser cache and cookies
Use an incognito window
Switch to a different browser or device
