A digital wallet is a software application that stores digital currency, such as cryptocurrencies or digital tokens, as well as traditional currency. It allows users to make transactions electronically, including sending and receiving payments, without the need for physical cash or cards. Digital wallets can be used for online purchases, peer-to-peer transactions, and in-person transactions with merchants that accept digital payments. They can be accessed through a mobile device, computer, or other electronic device, and often require authentication measures such as a password or biometric identification for security. Some examples of popular digital wallets include Meta Mask, Trust Wallet, and Coinbase.
