Greenfield, from-scratch firmware and tooling. Built only for Nockchain.
A teeny tiny touchscreen signer for Nockchain. Your seed never leaves the device — review, approve and sign every transaction offline.
Greenfield, from-scratch firmware and tooling. Built only for Nockchain.
Purpose-built for Nockchain signatures, lock trees, and transaction formats — m-of-n multisig, timelocks, hashlocks, and message signing — shared by the device and the browser app.
Open firmware and an open-source JS library. Build it from source, flash your own, and extend it — or install signed OTA updates from the web.
Your seed is generated (or imported) and stored on-device. Keys never touch the network — only signatures leave.
A capacitive 1.47" touchscreen decodes every transaction — recipients, amounts, and the actual lock conditions — and verifies them before you approve with your thumb (or a stylus, it's tiny).
Build, parse, and inspect Nockchain transactions in the browser — multisig, timelocks, hashlocks, HTLCs, even private lock-root-only outputs — then sign them on-device over WebHID/WebUSB.
Set a PIN and load a mnemonic on the device. Your seed is encrypted into a flash slot and never leaves.
Build or import a transaction in the browser composer, JS library, or CLI — plain sends, multisig, timelocks, HTLCs — and it streams to the device over USB.
The touchscreen decodes and verifies the transaction — recipients, amounts, locks — you approve it, and the signed result is exported back to your host.
Nockster assumes your computer is hostile. Keys are generated and sealed on-device; only signed results ever cross the wire.
Seeds are stored in flash with AES-256-GCM, keyed by a PIN-derived with a per-device salt.
The device decodes each transaction and verifies its lock tree — multisig thresholds, timelocks, hashlocks — against the committed lock-root, so a hostile host can't disguise where your coins actually go.
Hardened mode uses eFuse/HMAC-backed NVS keys, Secure Boot v2, and flash encryption — sealing the seed to the silicon itself.
Firmware update bundles are signed and verified on-device against a manifest before they can run.
The firmware is fully open source — compile it from source and flash your own build instead of trusting a vendor binary.
Built for Nockchain by some guys in Texas🇨🇱🔫🤠🤠.
