Wallet Contact

Overview

Contacts can store names, addresses, networks, memos, preferred assets, or payment references to reduce repeated data entry. They may exist locally, in a custody platform, in an organizational address book, or through a naming service.

A familiar name can create dangerous confidence. Addresses may change, provider deposit instructions can expire, contact records can be modified, and attackers can substitute look-alike values. One contact may also require different addresses for different networks or tokens.

Contact creation and changes should verify the recipient through an independent trusted channel. Systems need exact network-specific fields, change alerts, access control, and audit history. High-value organizations should use approval and cooling periods for new destinations. Users should still review the full address, network, asset, and memo for every payment rather than treating the contact label as proof.
