Wallet
Software or hardware that manages crypto keys, creates addresses, signs transactions, and shows blockchain activity.
A cryptocurrency wallet manages the keys needed to control assets recorded on a blockchain. The coins are not stored inside the wallet; the wallet proves ownership by signing transactions.
Wallets vary by custody and key storage. Hardware wallets keep keys offline, software wallets run on phones or computers, custodial wallets let a service control keys, and watch-only wallets monitor without signing.
Wallet safety depends on seed backups, device security, transaction review, and recovery planning. Self-custody gives control but also makes the user responsible for loss prevention.
