Illustrative data only

NOT PAIRED

Device pairing

A future Android pairing flow will authorize only watch-only/public portfolio data for this account.

LOCAL KEYS

Keys stay with the wallet

Seed phrases, WIFs, xprvs, Vault passwords and signing credentials are outside the web API contract.

WATCH-ONLY

Public portfolio data

The future dashboard can show authorized balances and public transaction history without giving the web service signing authority.

API TRUST BOUNDARY

The server gets a portfolio view, not a spending key.

The v1 contract is being prepared around explicit pairing, revocable sessions, least-privilege public data and server-side rejection of secret-bearing fields.
