The Trust Stack
Four layers of infrastructure that transform AI agents from unaccountable black boxes into auditable, insurable, compliant entities.
Why AI Agents Need an Identity Layer
Regulatory Risk
EU AI Act enforcement begins August 2026. Non-compliant AI systems face fines up to €35M or 7% of global revenue.
Liability Exposure
When an agent causes harm, who's responsible? Without identity and audit trails, liability is undefined and unlimited.
Uninsurable
Insurance carriers can't price risk for anonymous agents. No identity = no coverage = no enterprise deals.
The Trust Stack solves this by giving every AI agent a verifiable on-chain identity, connecting it to policy frameworks, enabling risk assessment, and providing proof of compliance.
Registry
LIVE NOWERC-8004 Agent Identity Registry
The foundational layer. Every AI agent gets a unique, immutable on-chain identity with cryptographic proof of registration. This is the anchor for all compliance, auditing, and trust scoring.
What Gets Registered
- Unique Agent ID (ERC-721 NFT)
- Registrant address (owner/operator)
- Metadata URI (capabilities, version, docs)
- Registration timestamp (immutable)
- Trust tier (UNVERIFIED → CERTIFIED)

Trust Tiers
Attestation System
Third parties can attest to agent capabilities, audits, or certifications. Attestations are on-chain and queryable.
AUDIT | CAPABILITY | CERTIFICATION | ENDORSEMENT
Governor
Q2 2026AP2 Policy Engine
Runtime policy enforcement for AI agents. Define what agents can and cannot do, enforce boundaries, and create audit trails for every action. Think of it as firewall rules for agent behavior.
Policy Capabilities
- Action allowlists/blocklists
- Rate limiting and quotas
- Data access boundaries
- Human-in-the-loop triggers
- Cost and resource caps
- Geographic/jurisdictional rules
Policy Format
Policies are defined in AP2 (Agent Policy Protocol) - a declarative YAML/JSON format designed for AI agent governance.
Example Policy
policy:
name: "production-agent-v1"
agent_id: "0x1234...abcd"
rules:
- action: "external_api_call"
allow:
- "api.stripe.com"
- "api.openai.com"
deny:
- "*" # Default deny
- action: "data_access"
scope: "customer_pii"
require: "human_approval"
- action: "spend"
limit: "$100/day"
alert_threshold: "$50"Integration Points
Governor integrates with MCP servers, LangChain, CrewAI, and custom agent frameworks via middleware SDKs. Policy violations are logged on-chain for audit trails.
Underwriter
Q3 2026Risk Scoring & Insurance Bridge
Quantified risk assessment for AI agents. Combines on-chain history, policy compliance, attestations, and behavioral analysis into a risk score that insurance carriers can actually use.
Risk Factors
- Registration age and stability
- Policy violation history
- Attestation count and quality
- Operator reputation score
- Capability risk classification
- Incident/claim history

Insurance Integration
Underwriter provides an API for insurance carriers to query agent risk profiles, enabling automated underwriting for AI liability coverage.
Proof
REFERENCE IMPLEMENTATIONx3o.ai Command Center
The Trust Stack isn't theoretical—it's running in production. x3o.ai Command Center is our reference implementation, demonstrating how enterprises can deploy compliant AI agent fleets at scale.
What It Demonstrates
- Multi-agent orchestration with Trinity AI
- Real-time policy enforcement
- Live trust score monitoring
- Compliance dashboard for auditors
- Incident response workflows
- Insurance-ready documentation
Trinity AI Architecture
Three specialized agents working in concert, each registered on the Trust Stack:
Why a Reference Implementation?
Enterprises need to see Trust Stack in action before committing. x3o.ai proves the architecture works at scale and provides a template for enterprise deployments.
