Xenith Seal

Proof-layer for autonomous AI - every decision cryptographically sealed.

Xenith Seal is developer-first middleware that wraps any AI agent or model with immutable audit recording, policy enforcement, and zero-knowledge compliance proofs. Invisible to end users. Essential to the enterprise deploying the AI - under 30ms overhead, thin SDK wrap. Built and deployed as an engagement, not a self-serve trial.

Shadow-mode pattern in under 1 day

Scoped engagement · enterprise roadmap

Arbitrum L2 anchoring · Groth16 ZK proofs · Policy smart contracts

Deployed as a scoped engagement for your stack - not a self-serve trial or live sandbox.

What a typical engagement delivers

SDK connected to one production AI workflow in shadow mode
First 1,000 decisions recorded with integrity monitoring live
One policy template deployed (fintech, healthcare, or custom draft)
Audit Console access with live decision feed

Shadow-mode pattern in under 1 day - built into your environment, handed over as a production system.

What's included

Typical engagement deliverables

Scoped to your stack and compliance needs. We deploy the working system into your environment and hand over runbooks - not a sandbox login.

SDK connected to one production AI workflow in shadow mode

First 1,000 decisions recorded with integrity monitoring live

One policy template deployed (fintech, healthcare, or custom draft)

Audit Console access with live decision feed

First anchored proof verifiable on a public L2 explorer

How it works

Two-line SDK (Node.js / Python) wraps existing OpenAI, Anthropic, LangChain, or LangGraph calls
Immutable decision hash chain: input + output + model ID + policy version, SHA-256 signed
Policy engine with fintech templates, data whitelist/blacklist, and human-in-the-loop escalation
Zero-knowledge proofs that compliance held - without exposing raw customer data
Merkle-batched anchoring to Arbitrum L2 for court-admissible, third-party verifiable records
Shadow mode: observe and score without blocking your production AI path
Fail-open by default so Seal never becomes a single point of failure
EU AI Act report templates auto-generated from your audit trail

Who this is for

Fintech: fair-lending and AML policies enforced on every credit decision an agent makes

Healthcare: prove an FDA-cleared model version produced a diagnostic without exposing PHI

Enterprise security: hard permission boundaries so agents physically cannot exceed policy

Regulators and auditors: verify any decision UUID via public API - no customer account required
