Watch payments arrive,
without the spend key
A view key can prove what arrived on an address without being able to spend a thing. The scanner replays the one-time-key math of the chain (crypto.cpp: output key = spendPub + Hs(8·view·txPub‖n)·G) over recent blocks, right in your browser. Perfect for cold storage, cashier duty, or proving a NervaLink payment landed.
What the view key sees
Every output your address can claim, as it lands, with tx hashes and confirmations. Enough to act, nothing to steal.
What it never sees
Amounts (sealed by RingCT), what you sent, and the spend key — the scan works from public chain data plus the view key only.
Where it runs
Entirely in this browser, against the public explorer API. The cursor and found payments persist locally per address — this device only.
