Definition
An address identifies a destination or account-like entity within a blockchain system. Its meaning and format depend on the protocol. Some addresses correspond to keys, while others refer to scripts or smart contracts. An address should not automatically be treated as a person’s identity or as a public key written in another form.
How It Is Used
Wallets display addresses so users can receive assets or interact with contracts. The network interprets the address according to its own rules. Similar-looking addresses can be valid on multiple networks, but the associated balances, assets and programs may differ. Additional identifiers, such as a memo or destination tag, may be required by a particular service.
Key Considerations
Verify the complete destination through a trusted source, together with the network and asset. Copying from transaction history alone can expose users to address-poisoning mistakes. An address is generally shareable for receiving funds, but publishing it may connect public activity to an identity. Knowing an address does not grant control of its assets; authorization depends on the relevant keys or program rules.
