Ledger Hardware Wallet
Ledger Hardware Wallet is a physical device that securely stores private keys for cryptocurrencies and other digital assets offline, protecting them from online threats like hacking and malware. It connects to computers or mobile devices via USB or Bluetooth to sign transactions, ensuring that sensitive keys never leave the device. This provides a high level of security for managing blockchain-based assets such as Bitcoin, Ethereum, and NFTs.
Developers should learn to use Ledger Hardware Wallet when building or interacting with cryptocurrency applications, decentralized finance (DeFi) platforms, or NFT marketplaces that require secure key management. It is essential for scenarios involving high-value transactions, long-term storage of digital assets, or compliance with security best practices in blockchain development, as it mitigates risks associated with software wallets and exchanges.
