The mechanism, in plain language. No account, no sign-up, no forms.
The flow
1
Checkout on any Aithne merchant
You choose anonymous shipping. Identity is never typed — it comes from your wallet's PIC (public identity credential).
2
Approve in your Aithne wallet
You approve sharing a PIC + a one-time addrToken. The consent screen tells you exactly what is shared (tokens only).
3
The merchant calls Malartu
estimateShipping → createShipment → startReturn, signed with the merchant's key. Tokens travel in request bodies only, masked, never logged.
4
The postal bridge fulfils
Malartu's per-country bridge adapter hands the pseudonymous shipment to your national postal service. A routing detail is materialized once, transiently, and never stored by Malartu or the merchant.
5
Tracking flows back, opaque
Status returns to your wallet as non-personal, opaque events — no personal data in either direction.
What Malartu sees / doesn't see
Sees
Pseudonymous ids from the wallet (PIC, pptId).
Tokens (addrToken) — to authorize routing, scoped, short-lived.
Opaque shipment + tracking status.
Never sees, never stores, never logs
Your name, your routing details, your contact, your payment data.
Raw tokens — only masked renderings, hashes, and transient in-memory values.
Any personal data in logs, errors, URLs, or analytics.
