Sovereign Signing for AI Agents
AI agents that manage capital need more than software guardrails. They need hardware-enforced policy, physical kill switches, and cryptographic proof of every action.
The Problem
By 2035, the AI agent economy is projected to reach $263B. Autonomous agents will execute trades, manage portfolios, and move capital without human intervention. But today, every agent operates on a trust-me basis: software policies that the agent itself (or its operator) can bypass.
Software-Only Controls
- • Operator can disable risk limits at runtime
- • No proof the agent followed policy
- • Kill switch is a config flag (bypassable)
- • Audit trail is software logs (tamperable)
Hardware-Enforced Controls
- • Policy evaluated inside tamper-proof enclave
- • Every action attested with PCR0 signature
- • Kill switch is physical (jitter monitor)
- • Audit trail is cryptographically chained
How It Works
ZeroCopy sits between the AI agent and the blockchain/exchange. Every transaction request passes through three hardware-enforced gates before a signature is produced:
EU AI Act Article 14 Compliance
Article 14 mandates "human oversight" for high-risk AI systems. ZeroCopy satisfies this with hardware-enforced policy bounds: agents can only operate within pre-approved parameters, and a physical kill switch (jitter monitor) can halt all operations independent of software state.

Policy Engine
6 rule types enforced in hardware with zero-allocation evaluation. Notional limits, rate limiting, contract restrictions, time windows, and AI risk scoring.
Hardware Kill Switch
Jitter monitoring with 30µs warning / 50µs critical thresholds. Circuit breakers with 2.5% max drawdown. EU AI Act Article 14 compliance.
Attestation Trail
Every agent action generates a PCR0-signed attestation document proving it operated within policy bounds. SEC 17a-4 compliant audit trail.
