Ledger
Ledger produces hardware wallets, referred to on its site as "signers," that store the private keys used to access cryptocurrency and interact with blockchain networks. These devices are paired with the Ledger Wallet app, which lets customers send, receive, buy, swap, and stake crypto, track balances, and connect to decentralized applications across multiple chains.
The company describes crypto wallets generally as tools that hold a private key, which signs transactions, and a public key, used to receive funds. Ledger's own materials state that private keys must be kept secure and secret, and that whoever controls them controls the associated assets, positioning its hardware signers as the mechanism for keeping those keys offline.
