Quick fixes when your wallet won't connect or signatures fail.
Problem: Wallet Not Showing on opensea.io
Ensure your wallet extension (MetaMask) is enabled and unlocked.
Refresh the page and try connecting again.
Try a different browser (Chrome/Brave) or disable conflicting extensions.
Problem: WalletConnect QR Fails
Update your mobile wallet app and scan the QR again.
Make sure the device has a stable internet connection.
Problem: “Signature” Looks Suspicious
Read the message — authentication signatures are short and only confirm wallet ownership. Reject any signature that requests transfers or spending permissions.
