A public BIP-352 silent-payments scanning service, served straight from our own Bitcoin full node — no third-party backend. Point a compatible wallet at one of the two endpoints below to detect silent-payments sent to you.
Client-side filtering — your keys never leave your device.
Endpoint
https://sp.mineracks.com
Wallets: Silentium, Silent Amulet, BlindBit
Setup: in your wallet's settings, set the silent-payments / BlindBit indexer URL to the endpoint above. That's it.
Privacy: the server only serves public tweak data; your wallet downloads it and matches outputs locally with your scan key. We never see your keys or which payments are yours.
Remote scanner for Sparrow & Electrum-protocol wallets.
Endpoint (Electrum over SSL)
silentpay.mineracks.com : 50002
Wallets: Sparrow 2.5+, Electrum-SP clients
Setup (Sparrow): Settings → Server → Private Electrum; enter the host and port 50002, leave SSL on, accept the certificate fingerprint when prompted, then create a Silent Payments wallet.
Privacy trade-off: see below — this mode sends your scan key to the server.
In both options your spend key never leaves your wallet, so there is no custody risk either way — we can never move your funds. The difference is purely about privacy: who can see which payments are yours.
| BlindBit (Trustless) | Frigate (Remote scanner) | |
|---|---|---|
| Scan key | Never leaves your device | Sent to the server (held in RAM only, never written to disk) |
| What we could see | Nothing — only that some client requested public tweak data | Your incoming silent payments, for the duration of your scan session |
| Spend key / funds | Safe — never shared | Safe — never shared (only the spend public key is sent) |
| Best for | Maximum privacy; self-sovereign users | Convenience, light/mobile clients, Sparrow |
| Cost | More bandwidth (you download tweaks) | Light on the client; the server does the work |
For the strongest privacy, run BlindBit (or your own indexer). Frigate is offered because it's what Sparrow uses and it's far lighter for mobile — but you are trusting this operator with your receiving privacy while you scan. Both endpoints are served from our own node, never a third party.
The BitBox02 (Bitcoin-only edition) is the first hardware wallet able to make silent payments — the device itself helps construct the payment output (your private keys are needed to derive the recipient's output), so the secret stays on the hardware. That complements this service: BitBox02 to send to silent-payment addresses, this indexer to receive/detect them.
