Hardware Architecture

Technical Specifications

Designed for physical key custody and local user authorization. The perfect compromise between cryptographic isolation and human-in-the-loop consent.

SECURE ELEMENT

NXP SE050 (CC EAL6+)

Generates and stores the Ed25519 identity inside secure silicon. Keys are mathematically non-extractable.

CONTROLLER

RP2350 MCU

Drives the 1-bit display, capacitive touch, and USB interface. The MCU never has access to the private signing key.

DISPLAY

1.3" Sharp Memory LCD

Ultra-low-power 1-bit reflective display. Crisp, high-contrast monochrome screen for the character avatar consent UX.

PRESENCE

Capacitive Touch-to-Sign

Physical presence sensor. Signature requests must be authorized with a manual touch, blocking background malware attacks.

CONNECTIVITY

USB-C Connector

Standard USB-C bus-powered interface. No battery to decay, no wireless radios to exploit, works with any modern workstation.

ENCLOSURE

Matte Anodized Metal

Keyring-sized CNC-milled aluminum chassis in matte black with a signature lime (#e8ff9c) accent strip.

Security posture

A root of trust you can audit.

Every capability is designed so trust originates in hardware and follows the work across editors.

Ed25519 Cryptographic Identity

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.

Isolated Hardware Key Storage

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.

Cross-IDE Context Protocol

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.

BM25 Local Context Ranking

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.

Air-Gapped LLM Failover

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.

Attested Supply Chain Evidence

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.

How it works

From plug-in to provable delivery.

01

Pair the device

Plug in Matrix Scroll. It mints an Ed25519 identity inside the secure element and registers your public key.

02

Ground your agents

Digital Rain scans the active workspace and serves ranked context to your IDE over MCP.

03

Ship with proof

Every change is signed on-device, producing an auditable, hardware-attested delivery trail.
