Matrix Scroll is a hardware root of trust for AI-assisted software delivery. Sign your commits with keys that never leave the device, choosing between the simple USB-C Scroll Key or the interactive Scroll Token desk companion.
Built for the tools your team already ships in
Verify your AI commits with keys that never leave physical silicon. Choose between the zero-friction Scroll Key or the interactive Scroll Token desk companion.
$99 · On-device secure element cryptography packed into a simple, pocket-sized USB-C stick. Direct encrypted MCP activation.
Explore hardware specs →$199 · Premium desk character device. Adds the RP2040 display driver, 1.3" Sharp Memory LCD avatar, and physical touch-consent authorization.
Explore hardware specs →Designed for physical key custody and local user authorization. The perfect compromise between cryptographic isolation and human-in-the-loop consent.
Generates and stores the Ed25519 identity inside secure silicon. Keys are mathematically non-extractable.
Drives the 1-bit display, capacitive touch, and USB interface. The MCU never has access to the private signing key.
Ultra-low-power 1-bit reflective display. Crisp, high-contrast monochrome screen for the character avatar consent UX.
Physical presence sensor. Signature requests must be authorized with a manual touch, blocking background malware attacks.
Standard USB-C bus-powered interface. No battery to decay, no wireless radios to exploit, works with any modern workstation.
Keyring-sized CNC-milled aluminum chassis in matte black with a signature lime (#e8ff9c) accent strip.
Every capability is designed so trust originates in hardware and follows the work across editors.
Cryptographic proof of origin. Every code write is signed directly by the device key. This cryptographically attributes each change to a paired device, eliminating key spoofing and identity theft.
NXP SE050 Secure Element. Private signing keys are generated inside dedicated secure silicon and can never be extracted or copied. Even if a developer's laptop is compromised by malware, your production keys remain safe.
Universal editor support (MCP). Seamless integration across Cursor, VS Code, and JetBrains. Security and attribution policies are enforced uniformly, no matter which IDE your developers prefer.
Hallucination-free indexing. Our local relevance engine filters codebase context before it goes to the AI. This cuts context sent to the model and guarantees the AI only edits code using highly relevant local context.
Offline security compliance. Automatically falls back from cloud APIs to local models (like Ollama) when handling ultra-sensitive code or working offline. Zero source code leakage to third parties.
Audit-ready compliance. Generates tamper-proof, hardware-attested evidence for every single AI modification. This produces hardware-attested evidence that maps onto SOC 2 CC8 / SLSA provenance controls.
Plug in Matrix Scroll. It mints an Ed25519 identity inside the secure element and registers your public key.
Digital Rain scans the active workspace and serves ranked context to your IDE over MCP.
Every change is signed on-device, producing an auditable, hardware-attested delivery trail.
