- Ensure MetaMask extension is installed and unlocked.
- Reload the OpenSea page and try the Connect flow again.
- Disable other wallet extensions that might conflict (e.g., other Web3 providers).
- Try opening OpenSea in a new browser profile or a different browser.
WalletConnect pairing fails
- Confirm your mobile wallet app is up to date and supports WalletConnect v2 if required.
- Scan the QR code promptly—some QR sessions expire quickly.
- If pairing times out, close the session and create a fresh WalletConnect request.
Signature or transaction errors
- Check that your wallet has sufficient ETH (or required chain gas) for the transaction.
- Read signature content carefully — some dapps request approvals beyond a single tx.
- If txs fail repeatedly, copy the error text and check public forums/official docs (avoid clicking unknown links in forum answers).
Hardware wallet problems
- Ensure the hardware device is unlocked and the correct app (e.g., Ethereum) is open on device.
- For Ledger users: confirm Ledger Live is not interfering, or use the browser connection method recommended by your hardware vendor.
- Try reconnecting the device, use a different USB cable, or restart the host computer.
