Ledger is a hardware wallet manufacturer that produces physical devices for storing cryptocurrency private keys offline. Private keys stored on a Ledger device never leave the device — all transaction signing happens inside the secure element chip.

By keeping keys offline, hardware wallets protect against online threats such as malware, phishing, and remote attacks. Even if a computer connected to a Ledger is compromised, the private keys cannot be extracted.

Ledger devices support Solana and SPL tokens. They can be used with Phantom and Solflare wallets as a security layer, and are recommended for high-value wallets and multisig signers.
