You can pair your Ledger hardware wallet with the Slush Chrome Extension for an extra layer of security. Open the extension, navigate to the Profile menu, select Manage account, and select Setup Ledger. Ensure your Ledger is plugged in, unlocked, and has the Sui app open on the device. Once connected, your Ledger-protected accounts will appear with a "Ledger" badge next to the address.
Go to Profile > Manage account > Setup Ledger to start the pairing process.
