Address

In the context of Cryptocurrency, an ‘’’address’’’ is an alphanumeric string of characters representing the public half of a public/private key pair belonging to a specific user. Much like an email address, this identifier can be shared publicly, embedded in links, and presented as a QR code to other users in order to accept funds or assets on the respective blockchain.

A single user may have multiple addresses and their corresponding private keys across multiple blockchains and wallets. Cryptocurrency wallets in the form of software, browser extensions, apps, or hardware devices allow for the management of and access to addresses under a user’s control.

Services like the Ethereum Name Service (ENS) map human-friendly domain names to Ethereum addresses for a fee, allowing them to be more easily shared and remembered.
