Infrastructure

Built for zero-trust agent environments

01 / Core<br>Authorization Gateway

Every agent action passes through a deterministic gateway that issues Ed25519-signed authorization receipts. No LLM in the trust path. Each receipt is hash-chained to its predecessor, creating a tamper-evident audit trail.

02 / Compliance<br>Automated Compliance Reports

Generate audit-ready reports mapped to EU AI Act, DORA, HIPAA, SEC 17a-4, NIST, and OWASP. The auditor agent scans your receipt chain and produces compliance verdicts with evidence citations. LLM-sanitized output prevents prompt injection in audit artifacts.

03 / Identity<br>Verifiable Agent Identity

DPoP-bound agent registration with Ed25519 key pairs. Agents prove their identity via liveness challenges. Agent cards provide discoverable metadata. Compatible with SPIFFE workload identity standards.

04 / Integrity<br>Tamper-Proof Audit Trail

Receipts are organized into Merkle trees and anchored to Base L2. Anyone can independently verify the chain: recompute hashes, validate Ed25519 signatures, check Merkle proofs against on-chain roots. Full offline verification supported.

Compliance<br>Framework coverage

Automated mapping of your agent activity to six regulatory and security frameworks.

EU AI Act

DORA

HIPAA

SEC 17a-4

NIST AI RMF

OWASP LLM Top 10
