Wallet

Definition ∞ A digital wallet is a software or hardware application that stores public and private keys, enabling users to send, receive, and manage their digital assets on a blockchain. These wallets interact with the network to authorize transactions and display asset balances, serving as the primary interface for users to control their holdings. Security of the private keys held within a wallet is paramount to asset protection.
Context ∞ Discussions about wallets in crypto news often revolve around security best practices, the emergence of new wallet technologies (e.g., multi-signature, hardware wallets), and the user experience of different wallet interfaces. News also covers instances where wallets are compromised due to phishing or other security breaches, underscoring the importance of user diligence.
