Private InfrastructureFor Autonomous Agents

Your agent can spend without showing the internet what it's doing.
Set limits, approve purchases, keep strategy private.

Get Started

How Veil402 Works

Three layers of private financial infrastructure

Deposit & Configure

Deposit stablecoin into a pooled vault. Create agent identities, assign spending policies with daily limits, per-request caps, and merchant allowlists.

Agent Pays Privately

Your agent hits a merchant's 402 paywall. Veil402 evaluates the policy, and the pooled settlement identity pays — not your wallet. The merchant has no idea who's behind it.

Encrypted Audit Trail

Every transaction is encrypted with AES-256-GCM. Only you can decrypt. Revoke agent credentials instantly. Full control, full privacy.

Data

Built for Serious Agents

Policy Engine

14-step deterministic evaluation. Daily limits, per-request caps, merchant allowlists, endpoint restrictions, rate limiting.

Pooled Settlement

Merchants see Veil402's identity, not yours. Reduced on-chain linkability between owner and agent purchases.

Instant Revocation

Credential propagation in under 100ms. One click to cut off any agent immediately.

Double-Entry Ledger

Every transaction balances to zero. Six account types. Atomic reservations with capture/release.

Human-in-the-Loop

Set approval thresholds. Purchases above your limit require manual approval from the dashboard.

x402 Standard

Works with ANY x402 merchant. No merchant integration needed. The merchant doesn't even know Veil402 exists.

Drop-In SDKs

Works exactly like fetch. Payments happen automatically.

import { Veil402 } from '@veil402/sdk';const agent = new Veil402({credential: process.env.VEIL402_CREDENTIAL,});const response = await agent.fetch('https://api.example.com/market-data');const data = await response.json();console.log(data); // { btcUsd: 67432.10 }

npm install @veil402/sdk

Honest Privacy

We tell you exactly what Veil402 protects and what it doesn't.

What Veil402 Protects

Privacy from public blockchain observers
Reduced linkability between owner and purchases
Private internal agent balances and policies
Encrypted receipts and audit trail
Instant credential revocation

What Veil402 Does NOT Protect

Absolute anonymity (we reduce linkability, not guarantee it)
Privacy from Veil402 infrastructure (MVP is partially custodial)
Privacy from the merchant receiving the request
Timing correlation attacks (mitigated by pooling, not eliminated)
Network-level observation (use a proxy for IP privacy)
