Ledger is a hardware wallet — a physical USB device that stores your private keys offline.
Plain-English explanation
To use Ledger with Polymarket: connect Ledger to MetaMask, then connect MetaMask to Polymarket. Every signature goes to the Ledger for physical button-press confirmation. Seed phrase is backed up on paper; the device itself holds the active key.
