An AI-first trading firm needed to give their autonomous agents signing authority while maintaining strict operational guardrails. Software-level policy enforcement wasn't sufficient. They needed hardware-level guarantees.
This trading firm is at the frontier of AI-driven execution. They've built sophisticated agent models that make better trading decisions than human traders in many scenarios. But there was a critical gap: how do you give AI agents signing authority without risking catastrophic losses from edge-case bugs or misconfigurations?
Their previous approach was purely software-based:
They needed something stronger: hardware-level enforcement where policy violations become physically impossible, not just software-prevented. With that guarantee, they could confidently scale the agent fleet and let them trade autonomously.
ZeroCopy implemented Sentinel's custom policy engine rules directly in the enclave. The policy becomes part of the cryptographic signing pipeline—violations can't occur, even if the signing request itself is valid.
Architecture: Each agent gets a unique signing key stored in the enclave. When an agent requests a signature, the enclave checks the order against its policy rules before signing. If any rule is violated, the enclave refuses to sign—cryptographically proving the violation was blocked.
Agent A → Sign Request (with order details) → Enclave Policy Engine (check rules) → If all rules pass, sign; if any rule fails, reject and log → Signed order or error → Exchange
The firm deployed 5 initial agents with specific policies. Each agent can now execute independently without human approval. If an agent tries to violate its policy, the enclave refuses—no emergency halt needed, no manual intervention required. The policy is law.
Autonomous agents now operating continuously across Binance, Bybit, Deribit, and OKX. Each with unique policy guardrails. Execution decisions fully automated; no human approval delays.
Policy violations. Hardware enforcement means violations become cryptographically impossible, not just software-prevented. Compliance teams can audit with certainty.
Audit trail coverage. Every signature is cryptographically signed with policy context. Full regulatory compliance. Attestation proves policies were enforced.
Agent fleet scaling capacity. Team is now deploying 50+ agents without proportional risk. Each agent has its own policy enforced in hardware.
Within 6 weeks of deployment, the firm had deactivated their entire manual trading desk for the asset classes the agents cover. The agents generate 3.2x the daily P&L with zero policy incidents. The team went from requiring 3 FTE traders + 2 compliance officers monitoring these strategies to fully autonomous operation with hardware-backed compliance.
The regulatory team now uses Sentinel's attestation reports to prove policy compliance to their auditors—something that was operationally impossible before. They've built compliance into the infrastructure layer rather than relying on process.
Their competitive advantage shifted from "best traders" to "best infrastructure for autonomous agents." They're now exploring deployment of agents to new asset classes and venues—something they would never have attempted with pure software guardrails.
"For the first time, we can let our agents trade autonomously and actually sleep at night. We don't have to monitor them. The hardware enforces their guardrails. They can't violate policy even if they wanted to. That's the guarantee we needed."
Hardware-enforced policy guardrails. Cryptographic audit trails. Regulatory-grade compliance.
