Definition
In wallet operations, address verification can mean checking formatting, confirming the recipient or demonstrating control over an address. These are different checks. A syntactically valid blockchain address is not proof that it belongs to the intended person, supports the chosen asset or can be recovered if the transfer is wrong. The term can also mean residential-address verification in identity procedures; this article concerns blockchain destinations.
How It Works
A wallet may validate address length or a checksum before allowing a transfer. The sender must still match the network, token and any required memo or destination tag. In some contexts, a signed message can show control of the corresponding key, but the meaning depends on the signature scheme and the message. Control of an address does not automatically establish a legal identity or an honest counterparty.
Key Considerations
Obtain receiving instructions from a trusted source and compare the full destination rather than a few characters. For hardware wallets, check the address on the device when supported. A test transfer can add evidence but does not replace checking the final transaction. Avoid signing opaque requests merely labeled verification: some signatures can authorize spending or other consequential actions. Never provide private keys or recovery phrases to prove address ownership.
