The message that proves the user owns the address their EUR account pays out from.

## Overview

- Always `I hereby declare that I am the address owner.` Sign it with `personal_sign` (EIP-191) — `signingHash` is empty — by the wallet that signed in to the card program, and send it to [Link the Address](https://docs.aureahub.com/docs/cards-link-address.md) or [Authorization Link](https://docs.aureahub.com/docs/cards-iban-authorize.md).
- No card program session is needed.
